melanieg Posted May 26, 2009 Report Share Posted May 26, 2009 Do you guys backflush on a schedule or situationally? If the latter, in what situations? Thanks for all your info! - Melanie g. Quote Link to comment Share on other sites More sharing options...
PaulR Posted May 26, 2009 Report Share Posted May 26, 2009 I backwash when the PSI has gone up "enough." How much that is depends on your filter. I expect the manual provides some info on this. --paulr Quote Link to comment Share on other sites More sharing options...

We are thankful the pool was closed properly & seems to be working well. The hot tub that was here originally disappeared at some point; was actually yanked away from the power lines & the LIVE line left laying on the ground. Good times!

Pool-newb Posted May 26, 2009 Report Share Posted May 26, 2009 Usually a 10 psi rise in filter pressure indicates the need to backflush. It is almost always demand dependent; when opening a swamp you may need to do it several times an hour whereas if you have an indoor pool with no bathers and a good cl level it may last much much longer.

Ah, thank you. That explains why when we opened 'the swamp' we had to backflush every 2 hours or so 'cause . . . EwW. Quote Link to comment Share on other sites More sharing options...
PaulR Posted May 27, 2009 Report Share Posted May 27, 2009 Definitely on-demand... in CA there's no real reason to close for the winter, and that whole season I backwashed exactly once. --paulr Quote Link to comment Share on other sites More sharing options...
