Customer Reviews for Watts 1/2 in. Lead Free Brass Pressure Relief Valve

Good item, works very well

I've had 3 other Watts relief valves with the fixed 150 PSI and lever but those never lasted more than 2 years. I decided to try this model and it started leaking in 9 months. I call Watts to get it replaced under warranty but the Support rep gave me the run around and said I had to get my water pressure tested. After a dozen calls, I got a plummer out and he measured 94 PSI at the water meter in the home which is well below the 150 PSI set point. I called watts back and they still would not replace it. I'm now trying to find an alternate manufacturer. What a piece of junk!

Relief valve came a little slower than expected but it was exactly what I needed and the install is easy and adjusting is easy HD was very good on informing me when it was coming and when to come pick it up. Also when I showed up to pick it up they had it right there on the shelf so no waiting for employee to come and then go back to look for it. That is a huge plus!! Very happy with product and process of getting it. Would purchase again w/o hesitation.

What most do not know about these is almost always if it starts dripping, it is probably doing what you want. This valve is intended for relieving excess water pressure from heat expansion that is caused when your water heater is heating up your water, and the more cold water it has to heat the more heat expansion you will have and the excess water pressure needs to go somewhere, and one way or another something is going to give, the relief vale releasing it or a bust water connector under a sink, and I have seen this it will for sure happen while you are gone over the weekend. My suggestion is if you don't like the dripping water coming from this valve then change it up a little and add a expansion tank above the water heater. this should fix your problem and shouldn't even need the relief valve here. But on another note .-- DO not remove or plug off the T&P valve ( temperature and pressure relief valve) this valve is a must and is set at a much higher setting then the other. If you are having one of these dripping, then you are having the same problem most likely and need to add a expansion tank at the water heater, and if you already have one and still having the problem it is probably still the same tank to do with as these do go bad or sometimes just need to add air pressure to the expansion tank. Always make sure it is sired right . up to a 50 gallon will use a small 2 gallon tank and above that you should use a 4.8 gal. Also if and when you install or change out a water heater you need to install a new expansion tank and I would recommend new water flexes.Gas water heaters do not do well with the braided supply lines, either use stainless steel non braided type or copper, and cannot hard pipe these anymore in a place that requires earth quake strapping U.P.C. codes call for flexible connections to allow a little movement. If you take my advise on these things you should have no issues. HOWMAN 69. plumbing contractor, in the trade for 31 years

This is the third valve I am installing in a year. The previous ones (don't remember the brand, bought them in store) started dripping after a month or so, and once it starts leaking it just keeps increasing. This online product seems different. I have set it between 75 and 100 psi. I noticed it had leaked on several occasions, but then it stopped and dried out. This tells me the spring is doing its job, and the valve is responding normally to pressure spikes. So far, I am very satisfied with the purchase.

the valve was real easy to install it was needed to maintain good standings with the maker of the water heater
