Mine is propane, so I opted for buying a small 6 gallon that plugs into a regular wall plug and am going I can figure out how to hook it to my shower. That way I don't have to have the old one messed with because I can't afford to hire someone to mess with propane and I'm not going there. This one cost less then $200 on amazon and I sure couldn't fix or replace the other anywhere near that. Hoping it will work out.
