Deep sink p trap with garbage disposal issue

[Slav Pakhnyuk]

Hi everyone,

Remodeling my home and I had new countertops installed as well as a deep center drain under mount sink.

The existing drain in the wall is in the center of the cabinet as well as is the sink drain.

I did a p trap mock up (didn’t cement anything down yet) and wanted to check with you guys to make sure everything seems ok before I permanently install the threaded adapter and the 45 degree elbow.

My only concern is the tail pipe going to the sanitary tee in the wall is slightly sloped down away from the wall towards the p trap. It’s only a tiny bit but thought I’d mention it.

I’m trying to avoid opening up the wall to lower the drain. Any advice would be greatly appreciated!

When you lay a level from B to A, what does the bubble do?

I will check and let you know! I believe the B is slightly higher than A.

C and D are the shortest connection it can be. So there’s no way to raise the p trap at this point since the nut is pressed up against the pipe at the 90

I looked for a trap with a shorter rise on the input, without going to a full reversible, but I did not find one.

Maybe a trap with a reversable J-bend would solve that problem. https://terrylove.com/forums/index....be-installed-backwards-j-bend-lo-inlet.30064/

You can build your own trap but their still may be the problem of water sitting in the bottom of the disposal.

I have a clean out. Can I just use that and convert the top drain to a clean out?

You can use the clean out as the drain and cap off the top part. Google search "low profile traps". This on is a glued fit. I don't know if they are available with slip nuts.

I need a glued fit for the low profile trap? Or you’re saying I need a low profile trap to use the original drain?

#1 YOU CAN CUT THAT G/D 90 DOWN A COUPLE OF INCH'S AND THEN YOUR TRAP WILL FIT,
#2 BE AWARE THAT WITH YOUR TRAP THAT WATER WILL SET IN THE BOTTOM OF THE G/D
WHICH WILL CAUSE EARLY RUST OUT OF THE GRIND CHAMBER

Guys check this out. This is a mock-up of using the lower clean out for the p trap. Also I routed it to the other side to conserve more space. It fits nicely with the insta hot tank on the right side anyway.


Is it a problem that the clean out doesn’t have a sanitary tee? It’s just a sharp drop.

You disposer drains at 6.6" below the sink.
The Insinkerator 3/4 hp Evolution series drains at 6.0" below the sink. That might help.

It's just an option if a regular trap won't fit.

So swapping the g/d is an option.

What about draining to the clean out like I posted?

Changing the disposer picks up 0.6" or you could go with the cleanout if it's based on a santee fitting. There are cleanout tees (no bend) and santees with a bend to them.

 

[Slav Pakhnyuk]

Doesn't seem like there is a santee but just a regular tee. Can I still use the cleanout as the drain?

Sure, why not. It's going to be better than standing water in the disposer.

What are the implications of using the clean out with a non-santee? More likely to clog?

They like the waste to bend a bit to allow the snake to drop downward. You do have the cleanout above though.
