My pool has an older cl460 filter, I never saw the gauge go much off zero, once in a while I would see 2 lbs, even when priming. I've replaced the filter gauge and it now shows about 12 -14 ish lbs when at priming speed. At 1800 rpm it shows about3 or 4 lbs.
At 2500 rpm it goes to about 10 lbs
which I think is normal -I cleaned the 4 filter cartridges this week.
What do you think
is the low pressure normal at low rpm ?
im still working out what rpm I need to run for how many hours to get a couple water changes per day
thanks in advance
