## Questions & Answers

**Q: Just making absolutely sure - my cleanout hole diameter is 3.5" with no threads. This will fit and tighten up?**
A: yes, this should work for a cleanout hole that is exactly 3.5" in diameter. it holds max head pressure of 50 ft.

**Q: Will this fit a 3 1/4 opening?**
A: Probably yes.  The measurements of cleanouts can be deceptive.  Mine also measured 3-1/4 and yet a 3-1/2 metal fit-all plug worked just fine.  So give it a try.

**Q: Is this safe for drinking water applications?**
A: Item was used for sewar pipe cleanout. I dont think its intended for drinking water applications.

**Q: Is the seal waterproof?**
A: Yes it is waterproof. Essentially it is a pvc part and a rubber part. Tightening it will seal any liquids or smells from escaping from opening. Also because of the materials, in future will make for easy removal and/or replacement.
