: Contact the manufacturer. Ask them. PT valves aren't cheap. : : Actually, I would just replace a 20 year old heater. You are on borrowed : time. I have one that is 23 years old, but only use it a few months a year. : : I would contact them if I could find them . No one around here has either not heard of them OR remember t hem from "way back". Apparently it's a good product, and a very expensive one also from what I've been told, but the closest I've come to finding them is they might be a Canadian outfit. One plumbing supply warned me to be careful if I replace the valve - the threads might not match. I do have to admit it's super-efficient, fast and works like no other heater I've ever seen. It heats faster than you can use the hot water; we've never run out.
