Disposal installation

Oct 16, 2007 5 Replies

Hello, I've got a double sink. The garbage disposer going on the right. Do guys have any preference on using a straight discharge pipe on the disposal, or should I use two s-traps...one for the disposal and one for the left hand sink.



Thanks for your time.

Here's a good descripton of your options:

The end-outlet tee is what I always find. I suppose because it's cheaper. I've never seen an implementation of the double p-trap design. Of course, I'm always called for problems, and maybe a double p-trap is better.

FYI...That URL seems to be incorrect...takes me to a Survey Completion page.

Just bought this house last August. Redid the whole sink and added a disposal. My disposal is under the left sink. But, I went to HD and got a kit for this. Its plastic piping and has a straight pipe coming from the disposal into a T pipe at the other drain. Of course, my discharge is in the wall instead of the floor so it runs over to that.

I think the kit was about 25 bucks.

Hope that helps,

Oh, I want to add, I was not very happy with the gromit they supplied for the pipe where it fits into the disposal side wall. Its kinda flaky. They showed me a much beefyier (sp?) one that did the job at HD. Might get one of those too.

Sorry about that, Chief.
