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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Prevent backflow in 3/8" tubing.... *by N***1 on July 8, 2025* Perfect for preventing backflow into the bucket of bleach from the backstream injector I use with my power washer.
