To avoid expensive future problems, it’s important to connect your washing-machine water-supply lines correctly. Find a step-by-step guide on how to properly complete this project below.
Step 1 – Shutting off the Power
First, shut of the power of the washing machine to ensure your safety. Then, turn off the main water valve to prevent any water from entering the hose that you will install, as well as preventing the machine from turning on while working on it.
Step 2 – Measuring the Fill Hoses
Before you connect the water-supply hose to the plumbing, you should measure the distance from the tip of the washing machine’s hose to the plumbing to ensure the existing fill hose will reach. Now is also the time to repair any leaks in the water-supply line before continuing.
Step 3 – Extending the Hose, if Necessary
Washing machines often come with their own fill hoses. However, most fill hoses are just long enough to connect to the plumbing right next to the washing machine. If the location of the washing machine is slightly too far from the plumbing, you will have to exchange the hose with a longer one or extend the existing fill hose.
Extending the Hose
To extend the length of the hose, purchase a hose that has the same diameter as the existing hose, but is longer, and then connect it using a connector.
Replacing the Hose
To entirely change the existing hose, unscrew the gasket from the washing machine and then replace the existing hose with the new hose. Screw the gasket back in place.
Step 4 – Spreading Plumber’s Grease
Next, you should begin prepping the hoses by spreading plumber's grease.
Spreading Grease on the Threads
After you’ve lengthened the hose if necessary, spread some plumber’s grease on the threads of the connectors so that the hose will slip into your plumbing easily. Also, spread some of the grease onto the threads on the wall plumbing and the connections on the washing machine.
Spreading Grease on the Gaskets
Then, take out the gaskets. Use waterproof grease to coat all sides of the ring gasket. After you are done, put the gaskets back properly.
Step 5 – Identifying the Valves for Water Supply
Most washing machines have hot- and cold-water valves. It’s important to clearly identify these. They will be marked, so this should be easy.
For your water supply, the water connector for hot water will often be labeled with “H” or a red mark. It is also often located on the left side of the water supply wall. The other one is for cold water.
Step 6 – Connecting the Hoses
Once you have clearly identified the cold- and hot-water valves, carefully connect the hoses to the water supply. The water hose for hot water should be connected to the hot-water valve and the cold connector should be connected to the valve for cold water on the water supply wall.
Twisting the Thread Connection
Twist the thread connection to the threads at the water valve, and then tighten the hose connectors. Use adjustable pliers to make sure the connectors are tight.
Connecting to the Intake Valves
Connect the other end to the intake valve for hot water on the washing machine by using the same method. Repeat the procedure for the connectors, and hose and valves for cold water. Be sure to replace your washing-machine supply lines every few years.
