## Questions & Answers

**Q: How long do they last before replacement?**
A: I really cannot say. I installed one over a year ago and it is still working like new. I pulled it out about five months ago and it looked clean, so I put it right back. I estimate a lifetime of at least3 years before I might want to replace it.

**Q: Will this prevent water backup in an RV shower drain?**
A: Hi, This shower sink drain is suitable for standard 1.45”to 2.7" pipe, please reference to your RV shower drain.
Will prevent backflow of sewers, filter and prevent blocking.

**Q: How do you make it flush, not wobble?**
A: Trim the gasket.

### ⭐⭐⭐⭐⭐ Nose saver!
*by E***T on June 11, 2022*

This little gadget works like a charm. I'm not sure about durability, but if it cleans up as well as it stops shower drain odors, then it's a big winner. It came with no instructions; the product description video show how simple it is to assemble. It worked perfectly. Water drains as usual. I am so glad to have this.
