Common Questions
- What pressure does this relieve at?
- This is a calibrated valve — you set it. It adjusts over 20-200 psi, so it has no factory set point. Set it below the working pressure rating of the equipment you are protecting, and re-check the setting after installation.
- Can I use this on potable water?
- Yes. It is certified lead-free to NSF/ANSI 372, which is what plumbing codes require for any device in a drinking-water line.
