Just fired up the heater [Hayward H400ED2] for the first time this season and boy did it make a racket! Pipes were bouncing around and it sounded like an animal was stuck inside trying to get out. Poking around on the internet, it seems like it's likely the thermocouple valve. The heater is about 20 years old, so not entirely surprising. While I'm there, I'm also going to replace the bypass valve and would like to ream out the heat exchanger [we have very hard water and periodically have to de-scale the tile].
I see the Raypak Deliming Kit, but don't feel like spending $240 on a tool I'll use once or twice. I was thinking about a wire bush and extension. Would this work? Or, is there something better that people would recommend?
