How do you vent a basement washing machine?
Some homeowners prefer to hook their washing machines with a convenient drain line. But the right way to vent the machine is installing a standpipe and connecting it to the P-trap, and finally, the drain. The upper part of the basement vent has to rise five feet above the overflow level.
Can you vent a washer through a wall?
In many jurisdictions you have the option of an AAV – Air Admittance Valve, readily installed in a wall box behind the washer. An AAV involves a gravity seal that opens just when needed to let fresh air into the plumbing pipe. Just makes sure what you get is a real AAV, not just a cheap $3 check valve.
What is the code for washing machine drain pipe?
According to the Universal Plumbing Code, the standard drain size for a washing machine is 2 inches. The absolute minimum should be about 1 1/2 inches. However, keep in mind that wash load capacities can vary by up to 400% or more depending on the model.
