How To Change Your Washer's Supply Hoses

Blog

The hoses that supply the hot and cold water to your clothes washer may have been quietly doing their jobs for many years without any issues. Why should they be replaced if they show no obvious signs of wear or leaking?

Unfortunately, supply hoses may not show bulges or minor leaks before bursting and spilling their contents into the room in which the washer is located. Because supply hoses are pressurized, water will continue to flow from a burst hose until the supply valve that controls the flow of water to the hose is shut off. 

Washers are usually housed in a basement or storage area that may be infrequently visited, which could lead to a room being completely flooded before the burst hose is discovered and the water supply shut off.

It is very easy for an amateur plumber to replace the supply hoses to a washer. All you need is a few simple tools and a willingness to possibly get a little bit wet and dirty.

What do you need to change the supply hoses to your washer?

The hoses

Measure the length of your hoses to ensure that the new hoses reach your washer from the hose bibs (the metal hose connections). If the washer is located far from the hose connections and you can't find hoses that are long enough, you can buy two sets of smaller hoses and two male-to-male hose adapters to join them together.

Locking pliers 

These type of pliers adjust at the pivot point to match the circumference of the object to be grasped. They also have longer handles than regular pliers and supply greater leverage and a stronger grip. They are also referred to as channel locks.

Teflon tape

This thin plastic ribbon is used to seal threaded pipe or hose connections.

Bucket and rags or towels

The hoses will be filled with water, and when you disconnect them, you'll need to contain it and/or clean it up.

Removing the old hoses

Unplug the washer or turn off the breaker that supplied power to the washer to be safe from possible electric shock, then turn off the hot and cold water supply valves at the hose connections.

Use your locking pliers to gently (gripping too tightly may bend and distort the thin hose connector) grasp each hose connector and turn it counterclockwise until the hose is detached. Hold each hose upright when it is disconnected, then place the end of the hose into the bucket so the water will drain from the hose.

You will then disconnect the hoses from the washer in the same manner. Place rags or paper towels under the hoses, because there will still be some water in the hoses.

Connecting the new hoses

You will begin wrapping a few layers of teflon tape around the threaded male hose connections on the washer and at the supply valves. Wrap the tape around the threads in a clockwise direction, so when you attach the hose connectors, the tape will not be removed or disturbed.

Attach the hose connectors to the washer connections and turn them in a clockwise direction until they are hand tightened, then use the locking pliers to tighten them fully. Don't be surprised if you find dirt, cobwebs, and other unpleasant things behind your washer. Keep rags or paper towels handy.

Attach the hose connectors on the other ends of the hoses to the threaded connections at the supply valves in the same manner. If you need to join two hoses together with a male-to-male adapter, remember to use the teflon tape on all threaded connections, and connect the hoses to the adapter in the same manner as the other connections.

Turn on the supply valves, plug in the washer, and you're finished. For assistance, contact a plumbing company like Marcum Plumbing Services, Inc.
