Kitchen sink plumbing question

[GSPHUNTER]

I think new codes require AAVs to be installed. It's new to me. They may allow air in for proper drainage while preventing sewer fumes to escape. Kind of like a back draft damper on an exhaust vent. Just a guess on my behalf.

 

[Ucsdryder]

so you mean to tell me that you don't get the stanky poop smell up under there?

Not that I’ve noticed in the 4 years I’ve been here.

Looking at online diagrams most are set up similar.

Studor vents can work in both directions. Make sure you use the right one

 

[GSPHUNTER]

If the vent cap is going to stay, then maybe don't bother with the p-trap.
Changed my mind, keep the p-trap.

Wise.

Or convince your wife that her old sink is just fine and no need to be like every othere basic white girl with their farm sinks.

The first thing I fixed when we moved into our current house 20 years ago was replace that useless expensive porcelainized cast iron double sink with a large stainless single basin sink. My wife couldn't have cared less, but I don't tolerate useless very well.

Ditch the garbage disposal. If your on septic it fills your tank with hard to digest solids. If on city sewer your just sending your problems to them. They are noisy, stinky, "convenience" relics from the past.

Strip it all out and start over - PVC fittings are cheap, and you will get everything to fit the way you want it, instead of having to rig around the existing install.

Normal double sink are complete POSs. I'd take a single large sink over a double any day of the week.

Any chance of changing sink with one that has off set drain connection.

Offset drain connection is so much nicer. I wish I had done it yeaaaaars ago.

I like a large stainless sink with offset drain. I don’t care how “basic white girl” it is. It’s just so much more convenient.

That will work, but I would redo the piping and clean things up personally, you might even be able to do that without buying anything new.

I'm the one who decided to replace the double sink with a work station stainless one. If I ever move, one of the first things will be replacing the sink if it doesn't already have a work station sink. Tight radius corners are a must though, none of the 90 degree crap that is hard to clean, and none of the traditional bowl sizes radius that takes up space.


I don't really care if that is basic white girl or not.


Calling it a farm sink is bloody stupid though as I don't live on a farm.

Agree.

No changing now. We replaced counter tops.

Ok does this look like my fix? I’ll have to replumb the riser but that’s in my arsenal, I think.

First picture shows current situation, not enough room.

Second picture shows fix. Cut, rotate, add sleeve.

Rotate the bottom part of the p-trap to toward the back, and then the horizontal part back toward the front, and cut some of that horizontal sch40 off.. you'll need a new p-trap adapter tho since you'll cut it off.

If its still too long, what you said with the cut and add sleeve will work too.

 

[GSPHUNTER]

I was going to suggest cutting into where you show. If you make the trap out of Street and regular 90 s you will be able to adjust to hit the cut in TEE.

I'm not a plumber, just a guy with an old house, so take it with a grain of salt! Your new trap layout looks fine to me and I think the slip joint ones are fine. Easier to snake if you need to. If theres room to tuck it back so the trap is 90 degrees to the cabinet front you might be less likely to knock it out of place when getting things in and out of the cabinet.

A couple things that you might want to look into...(or not since its been fine for 10 years...)

• If you're already going to re-plumb, don't forget to keep the AAV at least 4" above where the disposal drain enters. I try to get them as high as possible but still accessible if it should fail.
• The trap on the dishwasher drain is (again just my non-plumber eye) not up to code because the trap arm isn't long enough. It should be 2x the pipe diameter at a minimum so a siphon can't form and empty the trap.
• If the white drain is PVC (and not painted ABS or something) it should be joined to the ABS sections with transition cement which I've always seen green in color. The black is only for ABS to ABS. If I was redoing the drain I'd just use whatever material its connecting to

Mission accomplished. Thanks everyone.
