washing machine in my basement venting
Posted by sal on May 15, 2002 at 10:49:26:
I am putting a washing machine in my basement. It will need to pump up about 6 feet (the pump can handle it) and then into the stack via an old drum trap.

I assume that the old drum trap (that accommodated the old washing machine) should go.

Can I discharge the washing machine discharge directly into the stack, or should I put in a P-Trap and also an in-line vent to make sure it doesn't siphon (as the connection between the washer and the piping will be tight)?

Thanks in advance for any words of wisdom.
