Review: A Standard 1-1/2” White P-Trap - This is a standard P-trap and worked quite well with other 1-1/2” components. The J part is a standard 3-1/2” on center. What makes it work for either 1-1/2” or 1-1/4” is the inclusion of two different washers (which is also fairly typical). We needed it because we installed a new vanity with a slightly different sink drain location. The horizontal arm of the existing P-trap was glued into the drain pipe at the wall and cut too short to reach the new sink drain. We really didn’t want to try to remove it and then have to glue the new one in its place. Instead, we cut the old one, leaving a little over an inch for the nut and washer; cut the new one to size; and used a 2-sided slip joint connector in between the two cut pieces. This way, future vanity replacements will be easier. We also needed an extension piece for the upper part of the J section of the P-trap in order to reach the new sink drain (taller vanity). This project was definitely a learning experience for us. Everything was pretty easy to install. We used the 1-1/2” washers everywhere except where the extension meets the sink drain. This P-trap worked well with the two pieces we bought locally. No glue or plumbers tape or putty or anything else was needed. The nuts and washers create a good seal. We checked everything several times and couldn’t find any leaks. The quality / durability seems to match that of the many other white plastic plumbing parts. No surprises. The price seems good considering it’s delivered. Of course, we ended up needing to visit the store for the other pieces we needed… but that’s on us.

## Questions & Answers

**Q: I have an 1-1/4 stem coming off my sink going into an 1-1/2 pipe in the wall this looks like what I need is that correct?**
A: The pipe coming out of your wall is 1 1/2". The stem from your sink drain pop up is 1 1/4". This trap comes with a reducing hut which will adapt from the 1 1/2" size of the trap to the 1 1/4" of the tail piece. So yes, it will work. FYI typical tailpiece for kitchen sink is 1 1/2" and bathroom sink is 1 1/4". Most homes have 1 1/2" pipes as rough in waste.

**Q: Can this be used for bathtub drainline?**
A: No. Bath tub drains are usually inaccessible so there would be no way to check for leaks. Thus you would need a sch 40 solvent weld P-trap. I would actually recommend getting a 2"x1-1/2"x1-1/2" reducing sanitary tee to attach the tub shoe & overflow to a 2" P-trap for better drainage.

**Q: do i need to go from a utility sink w/ 1-1/2 inch drainpipe to a p-trap (or not) into a garden hose?**
A: use the p-trap. it will hold a small amount of water to prevent smells from coming from the drain.

**Q: Where can I buy the convertor 1-1/4" of the sink tail pipe to 1-1/2" trap inlet.**
A: Lowe’s

### ⭐⭐⭐⭐⭐ Old house? Order an extra
*by M***A on May 20, 2024*

I ordered two kits, and I'm glad I did. Our 44 year old house required a longer segment, so I used the second kit to create an extension (the loop was unchanged, just the straight run was too short). After assembly, not a drop of leakage; those angled washers work very well.
