## Questions & Answers

**Q: This is a type of check valve correct? The ability to take the lid off serves what purpose? Could you run a snake down the line with the top off?**
A: Taking the lid off allows you to clear debris out of the valve. Yes--you get full access to the line from the top of the valve. I use it to drain a yard that floods during high tide. Works well.

**Q: Can this valve be used under ground?**
A: Yes, our Backwater valves can be used underground.  You can also install an access sleeve (straight piece of pipe) in order to service the valve at the surface.

**Q: I received this valve and it came with a seal for the flapper. However, the seal will not stay in the grove on the flapper. Any suggestions?**
A: Hi. It comes with 2 O rings,  one is for the flapper, add some syllicon glue, like the used on motor engines,  this backwater works really good,

**Q: Does this fit 3" schedule 40?**
A: Yes, 3" schedule 40 PVC
