## Questions & Answers

**Q: Does these work with a standard garden hose? Thank you!!**
A: If you bought the 91250 Superior pump, it came with 1-1/4-inch NPT discharge with 3/4-inch garden hose adapter that will fit onto the check valve. to the garden hose can be attached.

**Q: What exactly are the sizes of the adapters?**
A: Just as the description lists the sizes. 1 1/4 and 1 1/2 female pipe thread and 1 1/4 and 1 1/2 male pipe thread.

**Q: is this a swing flipper or ball style or center spring check valve?**
A: It is a hinged piece of plastic that is forced closed by the back pressure so it has to be installed per the instructions to keep from leaking.  I believe the hinge had to be up when the valve is in the horizontal positon.

**Q: Can you connect 2 of these together? We need 100ft to get to our drain**
A: Hi there,I am not sure why you would want to connect two check valves together. Doing this could cause issues with air locking and blocking the flow of water. One check valve mounted onto or within 24" of the pump is all you needThanks
