Customer Questions & Answers

Is the ceramic rod supposed to be loose?

I'm assuming that as the temperature rises, the rod extends to open the valve?

Will this work for a Bradford White Model # 1503LN10? 50 gallon

Asked by: Issa
Hi Issa, Each model of water heater is different. The same model number could vary depending on when it was manufactured. If possible, the best method would be to remove the T&P, take it any Home Depot store and compare with the three models in stock to match to the correct shank length. Thanks,

3/4 in. Bronze NCLX Temperature and Pressure Relief Valve with 1-1/4 in. Shank MNPT Inlet x FNPT Outlet is rated 4.4 out of 5 by 27.
Rated 3 out of 5 by from 1st one bad The first one I installed leaked would not seal on the inside poor seal,The second one is working so far

Rated 5 out of 5 by from easy retrofit, buy yourself a good wrench for install, its worth it. simple install as long as you are aware what you need to do to drain the tank to the pressure relief level. Depending on your install and drainage, you might get some practice working on your PVC skills as well. A few install videos on the web were great to make this an easy install.

Rated 5 out of 5 by from T & P Valve TNP valve work perfectly for my hot water tank as my old TNP valve was leaking and was able to stop it from leaking with anything else but a replacement
Date published: 2016-07-05
Rated 3 out of 5 by from Works, but... I replaced my original, apparently leaking, 6 yr old relief valve with this unit. Easy enough to install. Unfortunately, the new one continued to dribble water. After further diagnosis, I determined that the expansion tank was shot. The PRV was merely doing its job of relieving pressure because the faulty expansion tank (ruptured diaphragm) was allowing pressure to build up in the water heater. I wish the plumbing guy at HD had mentioned to check the expansion tank first. He only suggested opening the relief valve a few times to see if it would re-seat itself. Once I replaced the expansion tank the 'dribbling' stopped for good.

Rated 5 out of 5 by from Seemed to fix the problem I tested our original relief valve (about 5 yrs old) and it continually dripped after that. Purchased this replacement and it no longer leaks. Easy to install.

Rated 5 out of 5 by from The pressure is gone Easy to install..just make sure to use a pipe wrench. It just makes the job super easy. This product didn't fix my problem, but at least I know it's not the pressure relief valve.

Rated 5 out of 5 by from 3/4 in. Bronze NCLX Temperature and Pressure Relief Valve the valve is what you need to keep you from replacing your whole hot water heater when it starts leaking and that is all that is wrong with the heater
