Follow up layout- Disposal


I've decided to do some measurements. Then I mapped the layout with dimensions of sink and insinkerator compact. I want to keep the baffle tee as close as possible to the disposal to gain as much open area to the left and under the master sink as possible.

I attached the layout as pdf.

Please take a look at the layout and ask any clarifying questions you may have. Also I will need some code direction. For instance.

Is there supposed to be any elevation change on any horizontalx sections?

Thx for any help or direction in advance.

P.S. I live in San Diego CA

I would use the disposal 90 instead of the baffle tee. You would need to lengthen the tailpiece on the left some and loose a little height but the system will be less problematic.

E,

I take it you are not a big fan of the center baffle? So unless I am mistaken you are suggesting single baffle. So we will lose about 4 inches height correct? But better drainage from the disposal.

Is that correct? I will redo drawing based on your suggestion.

That's correct- you'll loose a little height but your disposal waste will flow past a vertical tee.
Caution- Verify the stub out elevation in the wall at the back of the cabinet. It can limit your options for the continuous waste configuration.

I agree a much better way of doing it.

Very helpful from you both.

Stub out is 12 " from floor. 7" above cabinet floor. Disposal outlet is 6 inch down from sink trap. Cabinet is 35" high. Right hand sink is 8 " deep.

So elevation from disposal out to stub should be in the neighborhood of about 12" minimum.

Will that meet code? Main sink will of course tee in lower. Is there a minimum rise required?

Do I use a sanitary tee or a baffle tee?

Use a end outlet waste and a flanged tail piece off the big sink.

Ghostmaker,

If I make the connection to the P trap from the large sink, then I lose all kinds of room in the sink area. Why can't I plumb to the P trap from the disposal and connect the large sink?

Right now that is the way my sink is plumbed. I will make a drawing of the current setup.

I think this way is what you want.
This is a kitchen faucet call I went on today.
When I saw this set up I thought of you

E,

Exactly what I need to do. I attached a picture of the orig setup here.

Now if I can find the heavier duty ABS schedule 40 stuff the original plumbing was done with. Funny thing though. It is all glued together. No cleanout or removable connections.

I am thinking maybe I should put a cleanout fitting at the stub just to make any drain problems easier to deal with.

Regardless I think I have what I need now.

Thx to all that responded. I feel confident now I will end up with a good and efficient draining solution.

It's just a matter of terminology....
Don't forget that you were chating with 3 j-man plumbers. It's easy to use terminology and expect others to follow along.

Now don't start with RC stuff or you'll be drawing pictures for me

My dad taught me to always place knowledge first.

I would rather acknowledge my ignorance then allow stupid pride to keep me from gaining the best advice available.

I am the jack of all trades type.
