Any ideas? It's off a gravity HW system we pulled out in December. Thrush pressure reducing valve and relief valve,can't vouch for the relief but the feeder was still good after what must be at least 70 years!

    That thrush is

    about 50-60 years old. I have something for you that I will post a pic of here tomorrow. Might be older?

    Yours looks older than mine!

    This Thrush  valve set was installed in 1955 and still works perfectly. That would make this one 55 years old and it certainly looks more modern than what you have.



     What's even more surprising is that the relief valve still does not

    leak, even after operating the testing lever. They certainly knew how to

    make a quality product back then!
