Appliance Water Supply Installation

Appliance water supply installation provides a safe, correctly fitted water connection for a washing machine or dishwasher. It’s ideal when you’re fitting a new appliance, replacing old pipework, or want a proper isolation valve and leak-tested connection for peace of mind.

More information

What appliance water supply installation covers

A planned installation or replacement of the water feed to your washing machine or dishwasher, completed neatly and tested before we leave.

  • Isolating the supply and confirming safe working conditions
  • Installing or replacing the correct tap, valve, and fittings for the appliance feed
  • Connecting the appliance hose securely with suitable seals
  • Checking pipework alignment and support to reduce strain and future leaks
  • Leak testing and functional checks once re-pressurised
  • Clear handover on how to isolate the appliance supply

When this service is most useful

  • You’re installing a new washing machine or dishwasher.
  • The existing appliance tap is seized, leaking, or difficult to access.
  • You’ve had drips from the hose connection or pipework.
  • You’re changing the kitchen or utility layout and need a feed moved or rerouted.
  • You want a tidy, reliable setup for a rental property or commercial kitchenette.

How the installation is carried out

First, the water supply is isolated and the existing connection is assessed. The correct valve and fittings are installed, then the appliance hose is connected and secured. Finally, the system is brought back up to pressure, checked for leaks, and tested to confirm normal operation.

After the job

You’ll be shown the isolation point for the appliance and what to look out for during the first few cycles. If pipework is ageing or access is tight, you’ll get practical options for improving reliability without unnecessary work.

Frequently Asked Questions

Can you install a dedicated isolation valve for the appliance?
Yes. A dedicated isolation valve makes it easier to disconnect the appliance for replacement or servicing, and helps limit damage if a hose fails. We’ll fit the correct type for the pipework and location.
Do washing machines and dishwashers need hot and cold feeds?
Most modern washing machines and dishwashers are cold-fill only, but some models may require different connections. If you can share the model details in advance, we can confirm what is needed before attending.
Will you check for leaks after connecting the appliance?
Yes. Connections are leak tested after re-pressurising, and we’ll confirm the feed is operating properly. If anything looks worn or unsuitable, we’ll explain your options before proceeding.
Can you move the water supply to a new location in the kitchen or utility room?
Often, yes. It depends on access, existing pipe routes, and what needs to be altered to keep the installation compliant and reliable. We’ll advise on the simplest safe route and what disruption to expect.
Do I need to turn the water off before you arrive?
No. We can isolate the supply as part of the work. If you already know where your main stop tap is, it can be helpful, but it’s not required.
