## Questions & Answers

**Q: Will this fit over 3" cast iron to the bell/socket of 3" s40 backwater valve? Or is there another option that will work better?**
A: This fitting is made to fit over 3" sch 40 pipe and over bell end of 3" fitting. Inside measurements of fitting are 3.5" and 4 " . Most 3 " cast is just under 3.5" OD. This fitting should work

**Q: Will this work for 3" copper to 3" pvc?**
A: No it is made to go from 3" pipe to the socket of a 3" fitting.  A regular 3" in fernco will tighten down enough to join 3" copper to 3" pvc sch 40

**Q: This coupling looks to big a little bigger on 1 end(which is what I need).  What are the inner diameters on both ends please?**
A: The smaller end is 3.5 inch I.D. and the bigger end is 4 inch I.D. , the smaller end fits over 3 inch sch. 40 PVC pipe and the bigger end fits over the bell end of a 3 inch sch. 40 fitting

**Q: What is the id of this?  is it 3 inches? thanks**
A: The inside diameter fits over a 3" PVC pipe perfectly.
