Watts 0372271 530C 3/4" Poppet Style Adjustable Relief Valve

I am using a jaccuzi pump for irrigation, and needed a blow off type of pressure regulator. I ran from the output back to the input, and set the pressure to 75 PSI. seems to be working. Mark.

Good quality product .

Nicely made but contains lead alloyed in the brass so risky?

Part as described easily installed.

A little over a year and it's still working fine

I used this on a cold water system where I had a very accurate built in brand new pressure gauge. This relief valve essentially failed at all pressure in the sense that it leaked regardless of the system pressure and regardless of the relief valve setting. Very annoying considering the cost. Also, the pressure markings are done in some type of black marker that comes off the first time you rub over it with your wet hand. Your hand is wet because the relief valve fails to hold. I assume either the rubber washer or the seat is defective. Product support was of no help.

This product contains lead. I don't see that in the product description. I can't use this in my household, it couldn't be safe.

Immediately after installing the piece, it started leaking. not from any of the threading but out of the relief port. I increased the pressure setting and it made no difference. It's a slow leak but i would expect something so expensive to be built better. I can't bring myself to uninstall it and go through the ordering and install process all over again.
