How to Connect Multiple Washing Machines to Water

Wrap plumbing tape around the threads of two T-splitters, which are T-shaped plumbing fixtures designed to supply water to more than one appliance. Screw the T-splitters into the hot and cold water supplies. Tighten the T-splitters with an adjustable plumbing wrench.

Screw the cap of a water supply hose to each end of the T-splitter connected to the cold water supply. Screw the cap on the opposite end of one supply line on the threads of one washing machine's intake. Screw the cap on the other supply line onto the other washing machine's intake. Tighten both caps with an adjustable plumbing wrench.

Screw the caps of two water supply lines onto the threads of the T-splitter connected to the hot water supply. Screw the caps on the opposite supply line ends onto the hot water intake of each washing machine and tighten the caps with an adjustable plumbing wrench.

Turn on the hot and cold water supply by rotating the shutoff valves until you hear water begin to flow. Check the connections for leaks. If you notice a leak, tighten the caps again.
