Background to Legionella

Lots of people know about waterborne Legionella and how dangerous it can be, but few realise how prevalent it is. The bacteria responsible for Legionnaires’ disease multiply between 20-45°c when nutrients are available, offering a large window of opportunity for proliferation if systems are not managed correctly.

What is Legionella and Legionnaires’ disease?

Legionella is a pathogenic group of bacteria that cause pneumonia-type illnesses, with the most serious being Legionnaires’ disease.  You usually get it by breathing in mist from water that contains Legionella. The mist may come from hot tubs, showers, or taps in large buildings.

While most of those who are exposed to Legionella will not become ill, it’s still vital to ensure water systems and their constituent parts are properly maintained. To remain compliant, businesses need to assess risks in their networks, manage any identified issues, and then prevent the possibility of an outbreak. All of this work requires documentation to remain on the right side of the law.

How is it controlled?

To control Legionella, the temperature of a plumbing system can be maintained so as to prevent growth. The ideal temperature for Legionella is between 25-42°C, but when water is heated above 50°C, 90% of strains die. It is therefore imperative to keep the temperature above this threshold.

A heating loop is used to circulate hot water around a building and keep the temperature constant, however there are “legs” which must branch off in order to supply mixers to taps and showers. When these outlets have not been used for a while, the water in these legs converges to ambient temperature where Legionella thrives.

The potentially fatal consequences of serious contamination mean routine monitoring and inspection of at-risk areas is critical for those in charge of buildings. In no other environment is this more important than public washrooms, where complex circulating hot water systems are commonplace.

For some time, it has been recognised that failings in these environments often result from sub-standard risk assessments that overlook the different parts of a plumbing network. In response, Health and Safety Executive (HSE) has revised its own technical guidance document (HSG274 Part 2) to combat avoidable failings in Legionella control. Keeping compliant and free from bacteria will keep staff and customers safe from contaminated water. Legionella outbreaks can never be fully eliminated but they can be mitigated with the right procedures in place.

The Solution

To restrict Legionella growth, we should monitor the temperature of each leg 24/7 and automatically purge the outlet when the temperature drops below the temperature threshold. The leg most at risk is just downstream from the mixer (where the orange arrow is in the diagram).

We also install sub meters on each tap (indicated by “SM” in the diagram) so we can document the time and amount of water consumed on each purge.

Remote Purging

The ability to remotely purge each outlet, either manually or automatically based on pre-set rules and alerts, requires controlling a solenoid valve. These purging valves can be installed fresh on a separate branch specially routed for flushing a system of outlets to waste, or in parallel with tap/shower sensor valves which may already in use, to act as a bypass.

However, this requires significant plumbing and additional costs for fittings. Alternatively, if sensor valves are being used, we can retrofit our system onto these and use an “electronic bypass” instead.

By connecting an electronic bypass, we can allow the system to act normally for the majority of the time, but also have the ability to control the valve whenever we like. This could be done remotely by the click of a mouse, or dictated by rules such as time since last use and/or temperature level.

Typical Results

The chart for a typical configuration on a tap using 3 temperature sensors to monitor the hot, cold and warm water and a flow sensor is shown below. The graphs show the hot, cold and warm temperatures converging to ambient temperature each night when not used, highlighting the increased risk of Legionella growth.

Frequently Asked Questions

General Questions

All our terms and conditions for our service and website can be found here.

There are 3 stages: plumbing, electrics, WiFi connection.

When plumbing the device in, the water supply may be turned off for a short amount of time. We recommend informing affected personnel at least 15 minutes beforehand that the water supply will be shut off, and at what times (normally less than an hour). Remind them to fill kettles, and that toilets will have 1 flush capacity during the period.

The electrics are much less intrusive, and in most cases, an existing plug socket can be used. If a new socket has to be installed, a qualified electrician will turn the circuit off for the area and spur off an existing socket nearby.

Once the device is plugged in, connection to WiFi is very simple. Please make sure you have the WiFi ID and password to hand, and have permission from the network manager, then head over to your dashboard to register the LeakNet device.

You can set customisable thresholds for time and volume of water expected, at any time within the online app. If LeakNet finds your water consumption has exceeded any of the threshold levels, you will get a warning. If the consumption persists without intervention, then a second threshold exists which will automatically turn the valve off. You can adjust the thresholds as often as you’d like until they suit your individual needs.
A learning mode can be used after one month of normal usage, which can assist in setting more detailed thresholds.

The power cable is 160 centimetres long, but can be extended up to an extra 10 metres with the optional extension cable. The cable diameter is just 3mm and comes in black and white, so it can easily be fitted under carpet or to a skirting board whilst not looking out of place.

You will only need to provide your email, in order to log in and receive any alerts from LeakNet. You may also add your mobile number in order to receive text alerts.

LeakNet will alert you twice after a large amount of water has be used, either via email or text.

In the first alert, you are able to respond and confirm normal usage to prevent the water supply from being shut off for that event.

If you do not respond, the second alert (some time later) will notify you that the water supply has been turned off to prevent water damage.

You can also disable the valve completely under “settings”.

The LeakNet base and its power supply are not waterproof. It should be installed in a safe place above any pipes, with the plug socket accessible after installation, in case of an emergency.

Anyone can use LeakNet! The user interface is intuitive and very easy to use.

The amount saved on water will depend on consumption, so large water users such as Universities, Schools, Hospitals, Care Homes, Supermarkets, Warehouses, Offices will have the most return on investment.

The time it takes to spot a leak depends on your learned settings, which will depend on your property type, historic consumption, location of LeakNet, time of the day, and day of the week.

For example, in a typical 3 bedroom house, the owners may have the alert time set to 40 minutes in the evenings. However, this time might be reduced to just 10 minutes when everyone is at work in the daytimes.

After a few weeks of normal consumption, you and LeakNet will have a firm understanding of the normal behaviour in your household, and will be able to automatically set these thresholds based on your unique habits.

LeakNet is modular and able to fit onto almost any pipe, which makes it suitable for both small houses and large buildings.

LeakNet is usually installed just past the mains supply stopcock. This is located where the water enters the property.

If more accuracy/resolution is needed, we recommend installing more sensors where the pipes branch off to different areas of the building.

LeakNet can be bought directly from our online store, or contact us if you are unsure which product to get.

A subscription fee for using the online service will be charged in the future, but all purchases before December 2017 automatically receive 6 months free service.

Technical questions

We can monitor and control the water flowing through pipe sizes anywhere up 108mm (copper). However, the smaller the pipe size, the more accurate the leak detection will work.

For the plumbers out there, we have 3 standard size fittings, which are 3/4″, 1″, and 2″ (all BSPP). In special cases, we can also support 4″ too.

Yes, all our fittings are WRAS approved. You can find out more about WRAS approval here.

We recommend installation to be carried out by a professional plumber, but we provide an excellent installation guide for DIY enthusiasts. Installation is straightforward for pipe sizes of 22mm and under.

LeakNet uses WiFi to connect to the internet. The WiFi ID and password are input on installation.

If ever your WiFi credentials change, the setup can be done by the owner again to correct the WiFi settings, without affecting your data.

No special software is needed. Only a web browser is required to access the online application via computer, tablet, or mobile device.

User documentation

The LED next to “Set” on the LeakNet base will flash red if there is a problem with LeakNet. If this happens, please contact us immediately.

The installation manual can be found in this PDF.

There are 3 lights (LEDs) on a LeakNet base:

  • Set (multicoloured)
  • Open (blue)
  • Close (red)

The “Open” and “Close” lights indicate the valve status.

The “Set” light indicates the status of the internet connection:

  • Breathing light blue: Normal operation – connected to the internet
  • Flashing dark blue: Waiting for Wi-Fi credentials
  • Flashing green: Connecting to Wi-Fi
  • Flashing light blue: Connecting to the internet
  • Flashing purple: Updating to new software
  • Flashing red: Error (please contact us if you get this)

For the ability to detect leaks, yes, the device needs to be connected to WiFi. However, data recording can continue for a few hours with no connection (then uploads this data the next time it connects).

Yes, LeakNet has to be plugged in at all times. However, it is possible to use a 12V battery as backup.

The user (aka the owner) who first configures the device will be able to use LeakNet remotely, however, they may also share access with other users. They may limit other user’s permissions such as setting the valve or adding more users under “settings”.

For the purposes of providing this information, you authorise Quensus to log all the data entering and leaving your Services. The collection of such data enables Quensus to identify the types of consumption but does not allow it to identify you in any manner whatsoever, unless you explicitly ask us to identify you.
    12. When you delete data from your Services, the deletion takes place in a manner similar to emptying the recycle bin on a computer. However, you accept that removed content may persist in backup copies for a reasonable period of time. Quensus bears no responsibility for the loss of data resulting from the deletion of content.
    13. You agree to notify Quensus immediately of any unauthorised use of the Services and any other breach of security.

    1. In order to use our Services, you need to create a Services Account and validate your email.
    2. At the moment of validation, Quensus may require you to pay for its Services and/or the purchase of additional services and other features, the services for which Quensus requires a payment are collectively referred to as the “Paid Services”.
    3. Information on validation and pricing is available at [link]
    4. When Quensus requires a payment for the provision of its Services, the following rules apply:
      1. The initial term for the provision of the Paid Services begins on the date that Quensus makes such services available to you and continues for the period selected by the User at the moment of purchase. If you do not choose a period, the initial term will be 30 days. Regardless of whether you choose the duration of the term or not, the term will automatically renew upon expiration, unless you provide Quensus with notice of non-renewal.
      2. Unless agreed otherwise, Quensus will charge your payment instrument monthly beginning on the date Quensus first provides the Paid Services to you. Quensus has the right to suspend the provision of the Paid Services in case of rejection of the charges to your payment instrument.
      3. You can provide Quensus with notice of non-renewal anytime through the procedure available in your Services Account. After receiving your notice of non-renewal, Quensus will continue to provide you with the Paid Services that you had purchased until the date of expiration of the term. Quensus will suspend the provision of the Paid Services that you decided not to renew on the Date of Effective Termination of the Paid Services. When you provide Quensus with notice of non-renewal, Quensus will not charge to your payment instrument any amount in relation to the Paid Services due to events occurring on or after the Date of Effective Termination of the Paid Services. These Terms will continue to apply following your notice of non-renewal until the Date of Effective Termination of the Paid Services,
      4. Unless otherwise expressly stated in the Terms or the invoices for the Paid Services, all amounts due to Quensus under this Article do not include any tax on value added, goods, services, sales, use, property, excise and any other tax, import or export duty or levy imposed on or in connection with the Paid Services (collectively, “Tax”). When required by the law to collect a Tax, Quensus will include such Tax in your invoice and you must either pay such Tax or provide evidence of your exemption from the Tax.
      5. Any obligation to pay any Tax that you, as a User, may be required to pay under any applicable law shall be borne exclusively by you. You agree to cooperate with Quensus by providing accurate and adequate information, as determined by Quensus, to determine whether any Tax is due.
      6. All payments to Quensus for the provision of the Paid Services shall be made without any withholding or deduction for any Tax, unless you are legally required to make a withholding or deduction.
      7. Quensus has the right to change the fees for its Paid Services. However, Quensus will notify you before making any changes to the fees.

    1. Quensus occasionally releases services that are still in the testing or evaluation phase (“Test Services”). Test Services are marked as ‘beta’, ‘preview’, ‘early access’, ‘evaluation’ or similar terms.
    2. You acknowledge that the Test Services may not be as reliable as other services or features provided by Quensus and subject to these Terms.
    3. You acknowledge that your use of the Test Services may expose you to risks of operational failures.
    4. Quensus may terminate the Test Services at any time, without any notice.
    5. You agree to provide prompt feedback regarding your experience with the Test Services in a form reasonably requested by Quensus. You agree that Quensus may use your feedback for any purpose, including product development purposes.
    6. You agree not to disclose any information regarding the Test Services to third parties and not to use such information for any purpose other than providing feedback to Quensus.

    1. When using our Services, you retain any right, title or interest in your trade secrets, inventions, trademarks, copyright and other intellectual property.
    2. The Services are protected by intellectual property rights in accordance with English and foreign laws. These Terms do not grant you any right, title or interest in any of our Services, in Quensus’ trademarks, logos and other intellectual property rights and in the content of other users of the Services.
    3. Quensus respects intellectual property rights. To this end, Quensus allows anyone to file notices of alleged copyright infringements in relation to the use of the Services. When Quensus considers a copyright infringement claim to be founded, it reserves the right to delete or disable content alleged to be infringing and suspend or terminate the Services Accounts of the infringers.

    1. Quensus may suspend the provision of its Services to you at any time without incurring any liability if:
      1. Quensus reasonably believes that you acted or are acting in breach of the Terms, including the Acceptable Use Policy;
      2. Quensus reasonably believes that you acted or are acting in breach of any applicable law;
      3. you fail to cooperate with Quensus’ investigations of suspected breaches or technical faults;
      4. Quensus reasonably believes that a User’s Services Account has been accessed by an unauthorised third party or its security has been compromised in any other manner;
      5. Quensus considers the suspension to be reasonably necessary to protect its network, its customers, its commercial interests or any other essential interest;
      6. Quensus is required by law or by a governmental authority to suspend its Services;
      7. you fail to validate your email within 3 days of registration;
    2. Quensus will give you reasonable advance notice of a suspension and will offer you the opportunity to cure the grounds underlying the suspension, when this appears to be possible in Quensus’ judgment.

    1. You have the right to terminate this agreement at any time by deleting your Services Account. The deletion of your account takes place in a manner similar to emptying the recycle bin on a computer. However, you accept that removed content may persist in backup copies for a reasonable period of time. Quensus bears no responsibility for the loss of data resulting from the deletion of your account. If you have purchased Paid Services your deletion of the Services Account will constitute notice of non-renewal in accordance with Article 8.5.c.
    2. Quensus may terminate this agreement without notice at any time for any reason.

    While Quensus strives to provide Services of the highest attainable quality, it cannot guarantee that it will always be able to do so. To the fullest extent permitted by the law, Quensus and its affiliates, suppliers and distributors make no warranties, either express or implied, about the Services. The Services are provided on an “AS IS” basis. Quensus also disclaim any warranties of merchantability, fitness for a particular purpose and non-infringement.


      1. To the fullest extent permitted by law, except for any liability for Quensus’ or its affiliates’ fraud, fraudulent misrepresentation or gross negligence, Quensus, its affiliates, suppliers or distributors shall not be liable for:
        1. any indirect, special, incidental, exemplary, or consequential loss or damages of any kind;
        2. any loss of profit or income;
        3. any loss of business or business opportunity;
        4. any loss or corruption of data;
        5. any anticipated savings or revenue;
        6. any punitive damages;
        7. any loss of goodwill or reputation; or
        8. any other loss that could have been avoided by the damaged party’s use of reasonable diligence.
      2. This will be regardless of whether or not Quensus or any of its affiliates has been warned of the possibility of such damages, and even if a remedy fails of its essential purpose.
      3. Quensus will not be in breach of the Terms if the failure to perform any of its obligations is due to an event beyond its control, such as significant failure of a part of the power grid, significant failure of the Internet, natural disaster, war, riot, insurrection, epidemic, strikes or other organised labour action, terrorism, or other events of a magnitude or type for which precautions are not generally taken in the industry.
      4. The maximum aggregate liability of Quensus, its affiliates, suppliers and distributors shall not exceed £ 20.

    You declare that Quensus is not legally prohibited to provide you the Services and that you are not subject to any embargo or restriction under applicable export laws. You agree that you will not use, import or export the Services in any manner which would cause Quensus or its affiliates to breach any applicable export control law, rule, or regulation. You agree that you will not allow access to or use of the Services by any persons or organisation that is subject to any embargo or restriction under applicable export laws.


    1. If Quensus, its affiliates, suppliers and distributors or any of their employees, agents, or suppliers (the “Indemnitees”) face a legal claim by a third party arising out of your negligence, breach of Terms or any applicable law, breach of your agreement with your customers, you will bear the costs associated with the claim and any damages award, fine, or any other amount that is imposed on the Indemnitees in relation to the claim.
    2. The obligation included in the previous paragraphs includes claims arising out of the acts or omissions of your employees or agents, any other person that you authorised to access the Services, and any person who gains unauthorised access to the Services due to your failure to use reasonable security measures.
    3. Quensus will choose legal counsel to defend the claim and will inform you on the choice. You agree to cooperate with Quensus’ in the defence of the claim. We may settle the claim only with your consent. However, you cannot unreasonably withhold, delay, condition or withdraw such consent.

    These Terms are governed by English law except for its conflicts of laws principles, unless otherwise required by a mandatory law of any other jurisdiction.


    1. Quensus wants to address your concerns without needing a formal legal case. If a dispute arises out of the Terms, before filing a claim against Quensus, you agree to attempt to resolve the dispute informally by contacting us at info@Quensus.com. Quensus will make any effort to achieve an amicable solution to the dispute. If the dispute is not resolved informally within 15 days from the date of the first email concerning such a dispute, you and Quensus are entitled to start legal proceedings.
    2. Any dispute arising out of the Terms, which is not resolved amicably in accordance with the preceding paragraph, is subject to the exclusive jurisdiction of the competent English court.
    3. You may only resolve disputes with us on an individual basis and may not bring a claim as a plaintiff or a class member in a class, consolidated or representative action. Class arbitrations, class actions, and consolidation with other arbitrations are not allowed.

    Quensus’ failure to enforce a provision of the Terms is not a waiver of its right to do so later. If a provision is found unenforceable, the remaining provisions of the Terms will remain in full effect and an enforceable term will be substituted reflecting our intent as closely as possible. You may not assign any of your rights under these Terms, and any such attempt will be void. Quensus may assign its rights to any of its affiliates or subsidiaries, or to any successor in interest of any business associated with the Services.


    Quensus may revise these Terms from time to time, and will always post the most current version on its website. If a revision meaningfully reduces your rights, we will notify you (by, for example, sending a message to the email address associated with your account, posting on our blog or on this page). By continuing to use or access the Services after the revisions come into effect, you agree to be bound by the revised Terms.


    These Terms constitute the entire agreement between you and Quensus with respect to the subject matter of these Terms, and supersede and replace any other prior or contemporaneous agreements, or terms and conditions applicable to the subject matter of these Terms. These Terms create no third-party beneficiary rights.


    We may increase the Fees without notice if any of the providers of HPP Third-party Services, such as AWS, raises the fees it charges to Quensus.


    In case of suspension of your Services Account or termination of the Terms, you will no longer have access to Your Data. You agree to keep a copy of Your Data on a platform different from ours. Quensus bears no responsibility for the partial or total loss of Your Data and has no obligation to assist you in recovering data that you stored with us.


    1. Quensus’ liability for any Third-party Service’s downtime shall not exceed an amount equal to the fees charged by the provider of such Third-party Service for the billing period during which the downtime occurred.
    2. If the provider of a Third-party Service does not charge any fee, Quensus shall not be liable for such Third-party Service’s downtime.

Security precautions in place to protect the loss, misuse or alteration of your information

When you give us personal information, we take steps to ensure that it’s treated securely.

Non-sensitive details (your email address etc.) are stored as standard practice on a server connected to the Internet, and this can never be guaranteed to be 100% secure.
