How to Find a Plumbing Cross Connection

A cross connection is the type of plumbing fixture that connects two pipes in a home. Using a cross connection means that the drinking water pipe is connected to a non-potable part of the plumbing system. A cross connection could be anything from lawn irrigation to air conditioning. Even a laundry tub could have a cross connection. To locate a plumbing cross connection, shut off the service valve on your washing machine and check the water supply line to your washing machine. If you can’t locate the cross connection, try shutting off the mixing valve on your washing machine. how to find a plumbing cross connection

Plumbing crossover is an unpleasant experience, especially during hand washing, face washing, and dishwashing. Not only is it unsanitary but it poses a health risk. While locating the cross connection, you might be able to locate it with a little help from a plumber.

Cross connections may also be caused by appliances like water softeners, washing machines, dishwashers, and water powered backup sump pump systems.

But there is another way to prevent a cross connection: installing an air gap at the cross connection points.
