Review: Fits perfectly
Review: 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.

## 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
