Here we are going to show you how to plumb in a dishwasher, but you can also use a similar technique to install most washing machines
Bear in mind that some designs may have specific requirements and fittings, so be sure to check the manufacturer’s instructions
Modern appliances are easy to fit, so as long as plumbing does not need to be rerouted, plumbing in a kitchen appliance is a straightforward task
If any plumbing does need to be rerouted, then it’s best to call in a qualified plumber
If you are fitting a new product, carefully inspect it for any damage prior to installation
If you don’t have an accessible socket to plug your kitchen appliance into, have an isolation switch fitted by a qualified electrician
Install the appliance onto a firm, level surface
Turn off the water supply at the mains before carrying out any plumbing work
Do it right
When removing your existing kitchen appliance, have a bucket and cloth to hand in case you need to empty any water from a pipe
Bear in mind that the appearance of some fittings may vary from those shown here
Once you’ve removed the old appliance, use tape to secure any loose pipes so that they are pointing upwards. This will stop water from dripping onto the floor as you dispose of the appliance
Consider buying an energy efficient appliance in order to reduce the amount of power you use
Always follow manufacturer’s advice for the appliance you are installing
Some kitchen appliances can be heavy so ask a friend for help to lift and move them
Step by step
Locate the stopcock and turn it clockwise to turn off the water supply.
Carefully slide your old dishwasher out and unplug it from the wall.
Disconnect the drainage waste hose from the drainage pipe and catch any water in a bucket.
Turn off the valve on the cold water pipe by turning it 90 degrees.
Twist the nut on the cold water pipe to disconnect it from the hose. Place a small bucket or bowl beneath the valve to catch any water that spills out.
Move your new dishwasher into position with the back facing the space where it is to be fitted.
Connect the cold water hose to the cold water supply. If necessary, hold onto the cold water supply pipe so that it doesn’t move as you tighten the house. Tighten by hand or with an adjustable spanner.
Open the cold water valve but don’t turn the mains water back on at this stage.
Connect the waste water hose to the drainage pipe which is usually located under the sink.
Use a screwdriver to tighten the hose clip and secure the pipe.
Plug the dishwasher in and turn the water back on at the mains supply. Check for any immediate leaks.
Before pushing the machine into position, run a rinse cycle to double check for leaks in the pipes.
If a leak does occur, check the connection between the supply and the cold water pipe and check the waste outlet connections. Call in a plumber if you can’t stop the leak.
If all is well, carefully slide the dishwasher into position, taking care not to squash or twist the pipes behind it.
If your appliance is an integrated model, fit a cabinet door as per manufacturer’s instructions.
