Plumbing in an appliance
The work usually means connecting the appliance’s fill hose to a cold water supply valve and its waste hose to a standpipe or a spigot on the sink trap. If you’re replacing an old machine in the same place, the valve and waste are usually already there and it’s a fairly quick job. The main risk is an old valve that’s seized or weeping.
Putting an appliance somewhere new takes more work. The plumber may need to run a new supply pipe and waste, sometimes through a cupboard or out through a wall, and that depends on how close you are to the sink and the existing drain.
On the electrical side, most appliances simply plug in. If there’s no socket where the appliance is going, adding one is electrical work. In a kitchen, adding a socket to an existing circuit usually isn’t notifiable under Building Regulations, but it should still be done by someone competent. A new circuit is notifiable.
Integrated appliances also need their doors fitted to the kitchen units, which some plumbers do and some leave to a kitchen fitter or carpenter.
Say where the appliance is going and add a photo of the space and the pipes behind it.
What to include when you post
A photo of the space usually tells a plumber most of what they need.
- Which appliance: washing machine, dishwasher, or both
- Whether it’s replacing an old one in the same place, or going somewhere new
- A photo of the space, and the pipes and valves behind it
- Whether it’s freestanding or integrated, and who’s fitting the door
- Whether there’s a socket in the right place
- Whether the old appliance needs taking away
- When the new one is being delivered
- How far the new position is from the sink, if it’s moving
If the appliance is already delivered and waiting, say so, as it helps the plumber plan the visit.
What to ask
Ask whether the price covers:
- disconnecting and removing the old appliance, and whether they’ll take it away
- new valves or waste fittings if the old ones are worn
- any new pipework if the appliance is moving
- fitting the door on an integrated model
- a test run to check for leaks
If you need a new socket, ask whether they’ll arrange an electrician or whether you need to find one.
Some retailers offer installation with delivery. Check what that covers, as some only do a straight swap and won’t fit new pipework. It’s also worth asking whether fitting by someone other than the retailer affects the appliance’s guarantee.

Questions
What people tend to ask before booking this job. For anything specific to your home, ask the tradesperson who takes it on when they get in touch.
Tell us in the job. Swapping like for like is usually quick; a new position may need new pipework and a new waste.
Usually not for a swap, as appliances plug in. A new socket in a new position is electrical work, and a new circuit is notifiable under Building Regulations.
Usually, yes. Mention it in your job so the plumber brings a replacement. Worn washing machine valves are a common cause of slow leaks behind the machine.
Often, yes. Many sink traps have a spigot for an appliance waste, or the plumber can fit one. They'll check it drains properly without backing up into the sink.
That's up to the plumber who takes your job. Ask when they quote, and check whether there's a charge for it.
