Historically, it was quite common for properties to be on a joint/shared supply pipe where one pipe from the main serves multiple properties.
Separating a supply involves the existing supply pipe being disconnected, and a new supply laid with a new connection to the mains. Please note, if you separate your supply, unless everyone on the shared supply also gets new supplies, the original shared supply will still be in use and your neighbours will still require rights to the pipework even if it runs under your property.
You might need to separate the water supply when:
- You’re experiencing lack of water pressure or flow which could be due to leakage
- You're renovating an old property, building or adding something new
- Existing pipes need an upgrade, especially if they're made of copper, lead, or galvanised metal
- You're dividing a single property into multiple properties
- Your current set up has been deemed unsuitable for metering and you want to be billed based on usage
- Your property currently shares a water supply with others, and you'd like your very own
Joint Supply Leakage Responsibility
Joint supplies can be complicated as they can serve multiple properties. The diagram below should help you understand your responsibilities should you experience a leak. Find out more about leakage.
Responsibility by Leak Location
Getting your own supply
If you’ve decided you want a separate supply take a look at the diagram below to understand where you will need to disconnect your supply. If all joint supplies are applying for separate supplies, then Affinity Water will disconnect at “All” on the water main. Please note that if you are in a similar scenario as property number 5 you will need to ask your neighbours’ permission to disconnect on their land.
