Easiest way to get rid of this S trap? (Kitchen sink)

[Corman2000]

Hi guys,

Bought a house that came with what is effectively a S-trap on the kitchen sink. Kitchen is going to be redone next summer, but I'd like to get rid of the smell the sink makes in the meantime if all it takes is some ABS and an hour of work. I was thinking lower the P-traps as far as possible, and cut the drop part as short as possible? The vent is pretty far away.

Thanks for any help.

There may be enough length in that horizontal section out of the trap where you could cut it, put in a T, run the vertical part of the T up as high as you can, and add an AAV. That would let you leave the rest intact.

The vent must be made before the drain line turns down after the trap. So, if that horizontal section isn't long enough, you could reconfigure the bits towards the wall to create enough length to insert the T.

I didn't know AAVs were a thing.

Yeah that should work nicely. It's going to be tight to get a fitting in that piece of pipe, but I can probably replace the P-trap and right-hand sink drain to get the needed length.

Thanks for the help!

If you cut off what is there and come out straight from the wall that would fix it. Then the p-trap isn't raised up with 45's.

terry fix is best avoid aav when possible, especially when its easy
