## Questions & Answers

**Q: Whats size it this?**
A: They are about 4" / 102mm and fit standard 4" clay / plastic exterior waste pipes. I don't know if they do different sizes as this was all I was looking for. A word of warning: if you are buying this product as pictured for a concrete pipe it is the wrong model. This style is designed for plastic pipes only as it fits exactly using O rings. The other model has a rubber seal - take another look and you'll see the difference. By the way, it is an excellent product if a little expensive in my opinion.

**Q: Does this Item come in two parts? There is normally an extension piece**
A: Mine came in one part. V snug fit! stopped our problem. Cant recommend enough!! I do check it roughly every two weeks to ensure its working correctly and check for nibbles.. Nothing so far!!!
