Sorry if not clear, this is for a clothes washing machine.

1) What would be the difference between a p trap and what I've got?

2) Why do I need a longer horizontal? I only have two stud bays to work in and I've already swept the washer box to the left as far as I could.

3) As for the 2" vent, it ties into a 3 above in the attic space. I've never had an issue with a 2' run in this manner. Out of a few homes and many washing machines, all have had a 2" vent at this point.

Thanks for your time!

Looks fine to me.....not sure what's up with the other posters....

Please ignore the AAV. It's a temporary measure to prevent gases until I can get the attic portion of the install done.

I think you need a longer stand pipe. Lower trap and up a little higher for the pump.

Let's see what the masters say.

Thanks very much, I couldn't find anything regarding minimum stand pipe, I found min 24" drain height for top load washer and 30" for front load but didn't find anything regarding stand pipe length.

I would drop that trap down....with today's modern washers the pumps really flood. You want lots of containment.

Alright guys, I raised the standpipe and tied the supply side up. Same with the vent, it will go into the attic once the run here is deemed good to go.

That should be better even though I might have dropped the trap some. Those minimums with how much force those new pumps, pump can be tricky. Also, why didn't you buy the valves with the built in arrestors?

Your arrestors need access panels I believe.

Anyhow, the work looks clean and organized.

I could only find this regarding the arrestors in the code manual I've been using online:



I didn't see anything regarding their accessibility. As for why I didn't purchase an integrated box, I couldn't find one at the three stores that I have access to.

Short supply on those to now....when will it end.
