Washing machines use a pair of hoses for the hot and cold water connections to the main plumbing lines in the laundry room. The hoses are equipped with a threaded coupler on each end, typically made of brass, that attaches to the pipes in the laundry room and the intake pipes on the back of the washing machine. Hooking up two washing machine hoses to create a longer hose connection requires a coupler available at appliance repair stores and gardening centers.
Twist the water valve knob on the laundry room wall clockwise to shut off the flow of water to the washing machine.

Unscrew the brass ring on the hose end from the wall pipe, using the pliers.
Insert one end of the coupler into the end of the hose and tighten.
Connect one end of a second hose to the other side of the coupler and tighten. Hook up the opposite end of the second hose to the wall pipe and tighten.
Turn on the water valve knob at the wall slowly to check for leaks in the connections. Tighten the coupler and hoses with pliers to eliminate leaking water.
