Common Questions

What pressure is it set to out of the box?

The adjustable reduced-pressure range of 152A 30-15 is 3 to 15 psi. Verify the outlet setting with a gauge after installation and adjust to your target pressure.

Does it include a strainer?

No - 152A 30-15 does not have an integral strainer. On dirty or older supply lines, install a separate inline strainer upstream to keep debris off the seat.

Does it come with a gauge?

No - 152A 30-15 has no gauge and no gauge tapping. Set the outlet pressure using a gauge elsewhere on the downstream piping.
