so your saying you can take the guts out of the pipe and replace that with guts from a similar part?
I've never had one apart, but there's a little stainless steel rod that goes into the pipe and it must have a seal of some kind around it. Not worried about my heater not working, just if that probable seal blew and steamed my foot off.
