How much is the output flow at over-pressure? I'm sure it changes with amount of over-pressure, but I mean, is it just a trickle, or can it flow well?

Rated 4 out of 5 by from Great product for replacing the water main relief vale to the house. Old unit was a fixed 75PSI ... Great product for replacing the water main relief vale to the house. Old unit was a fixed 75PSI and started leaking after about 3-4 years. The leak progressively got worse so I had the incoming supply checked. Our nity water ran at 78-85PSI so I decided to get this unit to also increase internal pressure a bit. not that the extra 5PSI or so is a big deal but this was easy to install and easy to use.

This valve did not work for my home due to the fact that the lowest pressure it would regulate was 75 pounds and my water system is at 30 pounds....returned it and went to a plumbing supply store and bought a Zurin that had 25 pounds as the low scale.
