Re: Head Backfill
I hit the system with the muratic acid cleanse twice a year so it shouldn't be the joker valve. I don't know anything about it but it's not funny.
I hear that a lot--but it doesn't quite work that way. Unless you disassymbled the head, you don't know if all areas are clean. They also lose elasticity. There are chemicals that folks use that cause damage (PG, baby oil, Lysol, certain holding tank treatments including those with formaldahyde). If it is over 1 year old and you have these symptoms, it is very likely the problem or at least is dismissed as a cause at your peril. If the valves were all closed, where could water come from but the large diameter hose to the tank?
Conventional wisdom holds that "joker" is a bastardization of "choker," but who knows.
