I was just curious if most people go by the pressure gauge or by time. The PB said to backwash every month or if the pressure rises 10psi. Well, after 2 months the pressure hasn't risen 1psi. I've backwashed twice anyway, but just wondering if that is truly necessary.
Also, what about cleaning filter grids. Does that really need to be done twice a year like the PB said? It seems that if the pressure is staying in line, then what's the point of cleaning the grids? I like that sort of stuff, so no big deal either way....just curious more than anything. I don't see a reason to do more maintenance than necessary either.
