Most Liked Positive Review

Replaced a leaky valve. This one works good.

The original pressure relief valve for my boiler was mounted on its side (contrary to instructions) and eventually developed a slow leak. I have had no problems with this valve since I mounted it (correctly). It looks like a heavy-duty product and is about 10% cheaper than the price for similar valves elsewhere.

Most Liked Negative Review

The valve seat leaks on new install

Can I exchange this valve for a new one? Or a better product.

Would definitely purchase again.

Just what I needed for a commercial boiler I was working on. Best price, beat my regular supply house by over $200 and I had it the next day.

This particular relief valve is not as common as some, but Supply House had it in stock and shipped it out quickly.

Did the job

Our pipe system is over 40 years old. This valve did the job and it is continuing to do the job well! Excellent Service and quick delivery.
