Good product

Received this product within 4-7 days. I didnt have to make an account to order but I would make one next time i need something. Good price, local stores were like 30 dollars more for the thermostat it was fairly easy to install. Replace the old one because it wouldnt ignite when twisted but new one did the job right. If Ihave problems i'll post back here! :) go coogs!

Missing Key Safety Parts

This valve was supposed to be the replacement for another Bradford White valve that's no longer made. The old one had leads to connect to a thermal switch, in line, with the thermocouple. Well, for some reason the "replacement" part does not include these leads anymore, so you either forego the safety of a thermal switch on your hot water heater (NOT A GOOD IDEA), or you McGyver/solder leads on yourself and risk ruining the part. Not a fun predicament when you're hoping to just swap in a new valve!!

I would buy this product again for sure.

It worked out great and my customer was so happy with having her hot water tank producing hot water again and she gave me a five star rating and a great review for a job well done.

Perfect Replacement for discontinued part

The gas control valve was delivered overnight, so there was very little down time for the hot water, Supply House to the rescue again.

Great delivery, great price, great product. Highly recommend

Ordered and price was okay as we really needed a great quality part that was made for our older gas water heater. It arrived as a box in a box, well packaged and we installed and it worked perfectly. No problems, no worries. We found cheaper prices online but QC, reputable dealer and lowest frustration was our priority, worked great. Thank you Supply House. Highly recommended.

Fixed my problem of water not getting hot

I had an issue of my water not getting very hot. I turned the heat up but showers didn't last very long and bath tub water would cool off before it was full. I examined the bottom of my tank and there was no sediment. The only significant part left was the gas valve control. I followed online videos on how to replace this safely and was able to fix safely in around an hour or so. This solved the problem and now my water heats as it should. Saved me from spending 10-20x as much on a new water heater.

Easy Replacement

Although this part is listed a a direct replacement for my original part number, visually, there are differences. Supply House answered the one question I put to them. Replacement was easy and it has been servicing me very well. It has resolved the initial issue of temperature lag from mineral corrosion. I will order from Supply House in the future.

We are not familiar with that setting. You may want to look through the Installation Guide (see link below) to see whether or not it is discussed. http://s3.pexsupply.com/manuals/1314894213432/62046_PROD_FILE.pdf
