Is this P trap acceptable?

[kevin przybocki]

I'm concerned it has too much rise after the dip.

That’s not correct but from the pic angle I can’t tell exactly the best way to correct it

I was thinking I could raise the P trap higher onto the down pipe that comes out of the disposal which would also reduce the vertical height after the P trap, hopefully to ~4". Maybe getting rid of that little vertical extension of pipe after the P trap.

You have a mess. You need to cut it out and start over.

Post another pic showing the piping near the back of the cabinet.

That is not a P-trap, it is a S-trap.


And no, that is not acceptable.

Here are two more photos with slightly different angles. One of them was while I was fixing a leak (which is how I noticed this unusual configuration) and has section of pipe is missing which I then replaced.

The P-trap must be vented before the drain line turns down.

 

[kevin przybocki]

I see. Can I use one of these?

 

[MicEd69]

Some local codes do not allow them. But yes, an AAV will physically work in your situation.

Thanks! in addition to the venting, should I also be concerned about the rise distance after the P? I think I read somewhere that it was supposed to be no more than 4" from the bottom of the P to the bottom of the horizontal section after the P.

 

[MicEd69]

The maximum recommended sealing depth of the P-trap is 4".

You've been hugely helpful! Thanks.
