Under the Kitchen Sink Help

[mglinka02]

I am in the process of remodeling the kitchen in my home. The house was built in the 60's in PA. There used to be a double sink and I am confused to why there are two separate drain pipes?

Also, what are the suggestions for when I install the new double sink?

If I had to guess I'd say it was likely set up to be vented like an island sink. Without seeing the drainage underneath, we don't know for sure

you can buy a 30 dollar camera google endoscope camera

it connects to your phone, usb cable. see what/where the pipes go/do

Regardless, the resultant plumbing will take the form of S-TRAPS won't they, unless as you said they were part of a Chicago Loop vent system?

I went into the basement and I see that both of those pipes lead to the same pipe. I am not anywhere close to a plumber so forgive me for my lack of terminology. Could it just be that they both do the same function?

The old set up had a garbage disposal and it drained to the right pipe and the other pipe was the drain for the other side of the sink.

Does this make sense?

 

[frodo]

it makes a difference which pipe is the vent, which is the drain

3 different piping scenero, witch one is it?

frodo,

If the original plumbing was as the OP described, they would have S-TRAPS, correct?

I understand why the cleanouts but why was the trap arm lowered?

He can now plumb either drain (dual sink) into one or either (both) loop(s) and be legal?

 

[frodo]

drain was lowered to put the co above it.

if the co is below it, it would serve no purpose.


no, only one pipe is the drain pipe, the other is the vent

the vent is always the pipe in the middle
so the base of the vent can be washed

Frodo,

It's picture number 2 that you drew

The pipe on the right was hooked up to the garbage disposal. The pipe on the left was hooked up to the other side of the sink. Both were S traps

 

[frodo]

do this....
