Connecting a washing machine doesn't require a plumber. This is a job that even a first time DIYer can handle. These machines work by spinning your dirty clothes around in a tub full of soapy water, which removes dirt and odors, and then spins them dry. To perform all those tasks, a washing machine requires four connections: hot water, cold water, sewer and electricity. Making these connections is relatively simple and requires no special tools.

Things You'll Need

  • Teflon tape
  • Pliers
  • Scissors

Position the washing machine in front of the two water connections (one for hot, one for cold) and drain pipe where it will be installed. Do not push it back into place yet, as you need room to work behind it as you make the connections.

Wrap the threads on the water-outlet faucets with Teflon plumber's tape. Make at least two turns around the threads. Trim off any remaining tape with the scissors. Do this for each faucet.

Wrap the threads on the washing machine inlets with the Teflon tape in a similar fashion. The inlets for the washing machine are generally located either at the top or in the middle of the back of the machine.

Connect a hose from the hot water outlet (usually colored red) to the hot water inlet onto the back of the machine. Thread the couplings at either end over the threads, then tighten with pliers. Do the same for the cold water hose as well.

Insert the gooseneck end of the drain hose from the back of the washing machine into the drain pipe. Secure the gooseneck in place with a plastic cable tie or piece of wire. Some washing machines come with fastening straps for the drain hose. Use these if available.

Plug the washing machine into an AC socket.

Open the valves for the water supply by turning them counterclockwise. Run a test load in the washing machine and check for proper operation, including filling and draining. Tighten any couplings if necessary. When satisfied, push the machine back to its final position.

Tips & Warnings

  • Always plug the washing machine into a GFCI (Ground Fault Circuit Interrupt) socket. This automatically cuts off the power to the appliance if a voltage leak is detected.
