Washing Machine Plumbing

The first step is to decide where to put your washer.
Think about where you'd like to put your new washing machine and make sure it's close to a water supply and is simple to get to. Here are a few things to remember as you decide where to put your new machine:

  • Ensure it will fit in the chosen location.
  • Place it on a flat, solid floor.
  • Do not install your washing machine near any heat-emitting device, such as a radiator, fireplace, boiler, etc.
  • Also, ensure it's somewhere warm enough to avoid freezing.
  • It's most practical if easy access to hot and cold water is nearby.

Preparatory Phase

Before installing your new washing machine, remove the packaging. In addition, make enough preparations for the location of your new appliance.

Tip: Your machine will last years if you regularly sweep and clean the surrounding area.


Make sure you know your way around electrical or plumbing repair, as this can be hazardous to you and your home. Also, a washing machine is big and heavy, so be careful and ask for help if you need to move it. The Easefix app offers multi-skilled plumbers near you for this task.

A Methodical Approach

Before you do anything more, check that the old washer is wholly detached and out of the way. If you're ready to get started, the following is a step-by-step process you need to know how to plumb a washing machine properly:

Step 1: Position the Washer

For your washing machine to work effectively, it should be on a level floor.
Adjust the height of the washer by twisting the feet counterclockwise, or turning them clockwise to raise it.

You can check the top of the washer for levelness with a spirit level (use the spirit level in both directions, front to back and side to side).
Once you get the machine positioned, secure it by tightening the nuts on the adjusted legs.

Step 2: Attach the Water Supply Hose

You can reuse an old washing machine water supply hose if it is in perfect condition, but new hoses are preferable in most cases.

Warning: if you tighten the hose too far, it is likely to leak.
Join the water supply hose (ensure it is long enough and never over-stretch it). It is best to refer to the manufacturer's instructions to make sure your hose is connected correctly.

Check for leaks and fix them before moving forward.

Step 3: Connect the Washing Machine Drain Hose.

One thing to keep in mind when connecting a machine to a sink waste or standpipe is that the standpipe must be larger than the drainage line.

Step 4: Plug the Washing Machine Into a Power Outlet

Plug the machine into an electrical outlet and you're ready to start using your washing machine.

How to Plumb a Washing Machine Waste Pipe

Discharging wastewater from your washing machine requires a connection to the sewer system. If you know how to plumb in a washing machine waste pipe, you can avoid paying a professional plumber to complete the job.

To dispose of trash, you must not use rainwater soak away but rather attach the waste pipe to the foul water sewer. An opening in the wall must be made for the waste pipe, with the width of the opening being equal to the pipe's diameter. The typical size is 4 centimeters but can be smaller.

You may dispose of your trash without lifting a finger if you use push-fit waste connectors and smooth off any burrs before joining them.

Reduce your compression waste by cutting and sanding the pipe before connecting it with a rubber washer and nut.

Discarded solvent weld pipe must be cut and sanded once more. The next step is to secure the line in the fitting with the help of solvent cement.

Plumbing In The Washer Under The Sink

If you haven't already done so, reading the instructions of your washing machine is an excellent first step. It will show you how to set up the washer correctly.

Are you confused about how to install a washing machine in the sink's base? The process is quite similar to that of a standard washing machine installation.
Turn off the water supply and look for the hose connections under the sink. Following the steps outlined in this article, connect the water supply, and drain lines and store the drain cap under the sink for future use.

The Right Way To Install A Washing Machine Drain Hose

Unfortunately, for a DIY novice, figuring out how to install a washing machine drain hose can be extremely perplexing. In most cases, a standpipe beneath the sink is where you'll be required to attach the drain hose.

Be that the standpipe's rim is 30 inches off the ground. Finally, it would help if you ran your drain line up and under your countertop or set up a non-return valve.

Installation Guidelines For A Combined Washing Machine And Dishwasher

If you do a lot of laundry or dishwashing, having a washing machine and dishwasher will save you a ton of time and effort. Curious about how to combine a washer and a dishwasher into one plumbing setup? These helpful tiny machines are easy to set up with the help of our best installation tips.

Find out if your washer needs to be run with hot water. A hot water connection is unnecessary for some types as they can run on a cold water source alone.
A dishwasher's water supply needs are typically limited to cold water.

Shut the main water supply if the hoses attached to your machines are too short to reach the plumbing as it is now. T-fittings and branch pipes provide for easy machine connection. Connect each machine's hose to its tiny stop valve. You won't need to turn off the water supply to separate the equipment.

Then, attach the washer's waste line to a P-trap-equipped standpipe. When finished, hook up the dishwasher's drain hose to the same standpipe.

Be sure there are no leaks after turning on the water, and check for that.
You will also need to plug in your new appliances to use them. So, go ahead and connec hem to an electrical outlet nearby.
