Perfect fit replacement

This was a replacement for a failed relief valve. The new unit was exactly the size and rating of the failed unit. It is good quality, installed without issues and has been working perfect for several weeks.

Perfect fit!

The T&P valve was used to replace an old one on a domestic hot water boiler. Price was great, shipped quickly and was installed easily. It doesn't get any better!
