Hi all, I have a very old Laars mini-therm JVS-125 powering the baseboard heating in my home. Recently the bypass valve has been leaking. I couldn't find the part number, wondering if someone can help me identify it, and what are the compatible parts to replace it. Thanks!

    A low mass boiler and low mass distribution? What is the purpose of the valve?  Those systems should rev up quickly
