Washing machine drain vent line?

Question

I am moving my washing machine from one wall to an adjoining wall in the same room. The total move distance is 10ft. I plan to tie the new drain line for the washing machine into the existing drain line with a Y connector. This means that the existing vent pipe will be upstream of the point where I tie in the new drain line to the existing drain line. Will the existing vent line work for the new drain configuration or do I need to add a new vent pipe at the new washing maching location?

Answer 1

codes usually call for less than 6 ft but it should work fine.

Answer 2

It should work ok as is. Try it with a small load first then move up in size; If the machine drains ok then the setup is fine.

Answer 3

Under UPC, the max length a 2" arm can be is 5 foot. That's center of vent to weir of trap.

Your wye connection description doesn't tell us much.

The opening of the vent is required to be higher than the trap.

An improperly installed system is harder for us plumbers to fix, cable out, or troubleshoot when the time comes.

Have you got a friend in plumbing you could ask some advice from?
