## Questions & Answers

**Q: Is this filter for low pressure ro system or hi pressure systems?**
A: Permeate production is pretty much linear with pressure. I run mine at 80 to 100 psi and get 2.5 gpm from a two stage system - a total of three membranes. So far I am very pleased with the Hydron BW 4040 s.

**Q: Is there a 2.5”X40” membrane?**
A: Yes

**Q: Is overnight shipping available**
A: Possibly

**Q: Can you town water through this ro?**
A: Yes
