What is your preferred sink p-trap?

[Temp945]

Hi all,

I'm installing two new sinks. I ran new PVC pipe to both sink locations.

Now I'm deciding on which p-traps to install and am surprised at the wide variety that exist.

I know I could just pick one and it would be fine - but I'm curious what those with experience prefer.

Chromed brass vs. PVC? Cleanout vs. no cleanout? Compression fitting vs. glued fitting? School me!

Thanks for reading!

If it is exposed I like a 17ga chrome tubular trap w/ brass nuts connected to a trap adapter at the wall, often it requires a deep flange to hide the adapter. 20ga traps are almost acceptable, 22ga are not. If you can't see it, a plastic tubular trap to a trap adapter is best. The heavier plastic glue traps have less tolerance, are harder to install and replace and have no real upside. If you need to run a snake and can't do it without pulling the trap it is much easier with a chrome or plastic tubular trap.

In a cabinet? Polypropylene (usually white plastic, but sometimes black). Slip -- not glued. Trap adapter at the wall. Functional. Easy to clean or re-position. I am not a pro.

No cleanout.

Well I'm glad I asked! My traps are going behind drawers in a cabinet and will not be visible.

I was considering either a sch-40 glued trap or a 17ga chrome with cleanout, just because these seemed like the most "deluxe" options.

I'm surprised to hear that you both prefer a regular plastic (polypropylene) trap, but your rationale does make sense.

I'm guessing just a cheapie polypropylene trap, like the one linked below is what you suggest?

PS: Reach - you are so much more of a pro than any of the local "pros" I have dealt with!

If the trap adapter is to glue onto the end of a 1-1/2 inch PVC pipe at the wall, that would be something like this:

If it goes into a hub (socket) of a PVC santee, then something like this:

I think the sch40 plastic glue traps w threaded union no cleanout. are better, more rugged perhaps hold up better against all the junk people pile up under sinks.
When I first started plumbing that was the only traps I used at the company I worked for . I seldom use them anymore , nobody seems to care its quicker going tubular, not that big a deal, but no question in my mind tubular cheaper and easier and a step below in quality but good enough.

As often as I'm pulling traps to get hair out of them, I prefer tubular. I've never understood why someone would glue a trap on a kitchen waste either. It makes more work for a plumber I guess, but then I'm a plumber and I don't want to bother with the extra work on my home every time I pull a trap.
