Thread: Washer Drain and Air Break

Installing Washer and utility sink in basement that is already plumbed with bathroom sink, water closet and tub. For water source Im tapping off existing lines to bath. For drains, Im adding a utility sink drain and a washer drain. So the existing sink, the new utility sink and the washer drain will all drain out the existing 2" drain (the tub has its own drain).

For the washer drain, do I need an air break. Fairfax 2009 Code says I do. I always assumed the distance from the end of the drain hose to the trap was the air break as long as the washer drain is not covered, taped etc? Is that right or do I need an air break added to the top of the washer drain? Also, is their a minimum distance from the top of the washer drain pipe and the weir of the trap?

In addition, I see no air vent for any of the basement bathroom plumbing... I assume its there in the slab somewhere or a wet vent? Do I need to vent the Washer Drain in between the P trap and 2" existing drain pipe?

Thanks.

Roscoe.

To many variables to answer your questions.
Would need to see what you have, drawing plans or photos might help.

But instead I think you should consult with a qualified LICENSED plumber.
and at the least get a book on basic home plumbing.
Always get the proper permits.
The inspection department are most often willing to offer you tips, sometimes even how to advice.

Thanks for the advice. I'm going down to the inspectors office tomorrow. I have a couple of plumbing books Im reading and have figured out a few things since posting. I have been looking for a Plumber who will be a consultant because I want to learn how to do this stuff. Its not rocket science. Any ideas how to find retired plumbers who will consult for a fee. The inspector may know.

Thanks'

City Inspectors can be a valuable source of information.

Not rocket science, but there is more to it than:
S#@! runs downhill, Hot on left, cold on right, and remember to clean under your fingernails.
