## Questions & Answers

**Q: Why does water remain at the bottom of the drain core?**
A: The drain keeps a bit of water at the bottom to stop bad smells and water from flowing back. This water barrier is like a mini-pond that gets refreshed every time you use the drain.

**Q: How should I choose between the 2.4‘’ and 3.3‘’ depth specifications?**
A: The deeper the specification, the more water it holds. If you're going to be away on a trip or business for an extended period without draining, the deeper specification will maintain the odor control for a longer time.(2.4''-20days ; 3.3''- 40days )

*by S***D on 15 December 2025*

I’m pretty sure one of our showers was built without a p-trap. I purchased this product because it functions like a p-trap in that it keeps some water in it to prevent fumes from coming through the drain pipe into our condo. It installed easily and simply. It’s made of quality materials. No more odor coming from the drain, and the sounds of water flowing down a shared drain pipe have been dramatically reduced. I like this product so much, I purchased a second to have as a backup if ever needed. Highly recommend!
