Low pressure in filter?

[Poolsean]

suction side restrictions will cause your filter pressure to decrease. Check your valve positions and make sure your skimmer and pump baskets are not clogged.

40 psi is pretty high for a clean filter pressure. Do you have infloor pop up cleaning system?

Low Amps on your SWG:
1) check your cell for scale
2) check your cell cord for damage of loose connection
3) verify your salt level is where it needs to be
4) how old is your cell? May be wearing out.

Well, it's always been that high on the filter so I don't know. Skimmer basket is fine (and good suction) but I'll check the pump basket (all valves seem to be operating correctly).

I think the problem with the cell was that it was clogged -- I cleaned it and I suspect it will be fine (only a year old). Salt level is fine (but zero Stabilizer so I'm having issues with it holding chlorine, natch -- will take care of all today).

Thanks as always for the help.

Oh, and yes we have an in-floor cleaning system, if that makes any difference (does that account for the higher pressure?)
