Our Leak Detection Process

We use a combination of the most up-to-date water leak detection equipment to accurately locate leaks internal and external leaks.

Accoustic Leak Detection

A digital ground microphone is a sensitive listening device that can be used to hear the sound of water escaping from a pipe.

 

By listening for the lowest, consistent noise detectable by the microphone, The noise is amplified so the leak noise can be heard more clearly.

 

The digital ground microphone is placed on the ground above the suspected leaking pipe, and readings are taken while moving along the pipe route until the leak position is detected.

Tracer Gas Leak Detection

To detect leaks in water pipes, a mixture of hydrogen (5%) and nitrogen (95%), called tracer gas, is injected into the pipe from a gas cylinder.

 

This gas is safe to use in drinking water supplies as it is non-toxic and non-corrosive. The hydrogen in the tracer gas, the lightest and smallest molecule in the atmosphere, exits at the leak point and rises to the surface.

 

The sensitive equipment detects the gas, helping pinpoint the leak’s location.

Before making your request, there are some steps to be taken before submission:

Step 1 - Confirm your water supplier

If you are a household customer and unsure who your water supplier is, you can check who provides your water and sewerage services by entering your postcode through the following link: find your supplier

Step 2- Confirm whether you have lead pipework

If you live in a home built post-1960 then it’s unlikely that your home has lead pipework. The use of lead was gradually phased out until change in building regulations prohibited its use in any newly constructed buildings from 1970.

Step 3 - Check your electrical earthing

If your building was constructed before 1966, the underground supply pipe we need to replace may provide the main earthing for your electrical system. This is a critical safety feature. If your electrical system has had any significant work carried out by a qualified electrician since 1966, then it’s likely that the main earthing is now provided by other means. 

 

You may also need to seek the advice of a qualified electrician to check your earthing arrangements before we start work.

Step 4 - Get us in to survey and provide a quote.

If you need help with how to complete any of the steps above, please call us on 0800 037 1247 to arrange for an approved plumber to visit your property.

 

During the visit, we will look to establish the most direct, least disruptive route for installing the replacement pipework.

 

To minimise disruption and reinstatement costs, we will always assess the feasibility of carrying out the external replacement works using Impact Moling

 

We will then be happy to provide you with a free, no-obligation quote for the work required and answer any other questions you have about the process.

Step 5 - Submit your request to the Thames Water Lead Replacement Scheme

If you’ve decided that it’s time to replace your lead supply pipe and plan to carry the work in within three months, you’ll need to complete the online application form requesting Thames Water replace the communication pipe on completion.

Ensuring your household is safe and free from potential health risks should always be a top priority. Affinity Water does provide its customers with a free lead replacement scheme similar to Thames Water’s and SES Water’s but with limitations. 

 

Affinity Water will replace any lead communication pipes for free. Still, in shared supply pipes, the offer is conditional that any other properties connected to the shared supply must also replace any lead pipework within their property for the request to stand.

 

If you live in an eligible property and want to learn more about this scheme and how to apply, visit the Affinity Water website.

Step 6 - Getting the work done.

We’ll make sure an exposed tail of the pipe is left at the boundary with enough length for the new pipe to be connected directly into the outside stopvalve and return on the scheduled day of connection to make the final connection of the new supply pipe to your internal plumbing.

 

Once we have completed the installation of the new pipe, we then issue a Certificate of Works Completed to confirm our new pipework satisfies both the lead pipe replacement scheme and the Water Supply (Water Fittings) Regulations. Issuing this certificate bypasses the need for the homeowner to arrange with Thames Water to carry out a regulation inspection.

 

Once Thames Water receives a copy of our Certificate of Works Completed, your job will be passed for connection. Thames Water’s fulfilment team will then arrange to replace the communication pipe from the water main to the boundary.

 

Thames Water can take up to three months to arrange and complete the connection from the date we submit our certificate. This time frame is dependent on any traffic management arrangements and Thames Water receiving the required permissions to complete their side of the replacement.

 

The new communication pipe Thames Water will be a minimum of 25mm MDPE. 25mm MDPE will be an increase in internal diameter over most lead supply pipes, which typically have an inner diameter of 3/8th of an inch.

 

If you would like to install a pipe size above 25mm, you won’t be able to do so under the free lead pipe replacement scheme. Instead, you’ll need to apply through the Thames Water Developer Services team to provide a formal quotation for the replacement connection.

SES Water Lead Pipe Replacement Scheme

For SES Water, a top priority is providing safe and clean water to all its customers. They recognise from hazards of lead in drinking water and have taken steps to address this issue.

 

They offer a free lead pipe replacement programme similar to that of Thames Water.

 

This programme involves the free replacement of the communication pipe after the lead pipework within its customer’s property boundary has been replaced. Both households and businesses with either a single or shared supply pipe can apply for this scheme.

 

To learn more from SES Water about lead in drinking water,  if you would like to replace your lead pipewapply for the Free Lead Pipe Replacement Scheme by submitting the required information

Affinity Water Lead Pipe Replacement Scheme

Ensuring that your household is safe and free from any potential health risks should always be a top priority. Affinity Water does provide its customers a free lead replacement scheme similar to Thames Water’s and SES Water but with limitations. 

 

Affinity Water will replace any lead communication pipes for free, but in cases of shared supply pipes, the offer is conditional that any other properties connected to the shared supply must also replace any lead pipework within their property for the offer to stand.
