## Questions & Answers

**Q: What is the opening force required for these valves**
A: It isn't very much. I used one to replace the check valve in my door drain in my walk-in tub which would only have at worst a 3 -4 inches of standing water in the tube and It allowed the water to pass.

**Q: Will this work if tubing is laid sideways?**
A: Yes it will work in any position.

**Q: Where do I put this on a portable a/c condensation line. Close to the unit or down the line further. It will be on a 10 ft clear flexible tubing?**
A: If you using a condensate pump put it as close to the pump as you can. If you not using a pump and using gravity draining you don't need it.

**Q: Can this be used on a submersible 600gph water pump for the basement?**
A: Check valves of this size are meant for use in smaller capacity pumps such as condensate pumps for air conditioners or dehumidifiers.  Not for basement  pumps.
