Reasons for low pressure/low flow?
I have a newish pool with all Pentair equipment including a 4x160 pump, intellichlor salt cell and a cartridge filter.
The pressure gauge on the filter has 20psi marked as "Start" and 25 or 30psi (don't remember) marked as "Clean".
When I run the pump at 2500rpm in pool mode, the reading is only around 12psi and it has been like that for some time although we believe it was higher when the pool first started up. In addition, even though my Intellichlor is producing chlorine just fine (all green lights), the diagnostics on the EasyTouch say "Check Flow/PCB".
If the pool is clean, the water features working as expected and the chlorine level acceptable, is there any need to worry about the PSI?
