I received this pressure relief valve quickly & most importantly, it was easy to install & a perfect fit. It's Saturday afternoon & the occasional drip from my at least 25 year old valve suddenly became a spray. I couldn't find one locally. No one had any idea what I was talking about. Both H.D. & the big L were clueless. One of the employees at H.D. suggested that I try "a real hardware store". Nothing locally was open, so I jumped on Amazon. There it is, exactly what I needed & I could get it on Monday. I didn't want to take a chance that I would run around half the day Monday & still not be able to find a valve. Order placed. Monday comes, there's my package & 15 minutes later, no more leak. Now my sump pump isn't running every 30 minuter, yea!!! 5 Star product & service. If you need a 3/4" blow off valve for your boiler, this is the one to get. Just don't be like me & wait too long. When the trickle became a flood, I knew that I had done it again. DOH! GG - arbez

Needed a direct replacement for an existing valve that was starting to fail. Purchased this one based on specs and price. Installation took approx. 30 minutes. No problems.

This relief valve is the best you can buy. It is best price around. I checked Home depot, Valu and Ace, this one is best and cheapest.

Replaced the leaking Pressure valve on my boiler. Furnace has been running all winter now without any leaks.

Fast shipping and reasonable price. It is installed and works as expected.

Prefect. However, be warned, once it blows, it is next to impossible to ever reset. Buy 2 at a time because your local pluming stores will only carry the one with the blue tag which requires a nipple to change the gender if you require a male end like this one.

I've installed quite a few of these and they last as long as the more expensive ones.

Works as advertised, easy installation, no more water leaks.

Replacement of original part. My 12 year old Valve was leaking at lower pressure then valve rated for. Changed valve no more leaks. 15 min job. Just remember to bleed the pressure and make sure water is not hot. Otherwise, you will get sprayed w hot water when you remove the valve!

Works perfect. Was direct replacement to original boiler valve.
