I had a Pentair DE Quad filter recently installed for my salt water pool. I am stumped because I can not get the pressure to drop to a "normal" number. Here are the details:
Here is what I have tested:
What am I missing? What else could be causing this issue? Any thoughts or suggestions would be greatly appreciated as I am out of things to try.
Thank you
- After cleaning the pressure is 25lbs
- Within a month the pressure climbs to 30 lbs - at which the chlorinator no longer functions because of low flow rate
- I am currently cleaning the filter cartridges every 30 days
- I have replaced the pressure gauge - no change
- Even if I remove all filter elements (so it is just an empty tank), the pressure is still 25lbs
- If I remove the chlorinator, the pressure drops a few pounds (~2lbs)
- I have bypassed the heater with no impact
- The pressure is unchanged if I change the output from Pool to SPA (trying to see if there was a blockage downstream)
- I have taken out all values and ensure everything is clean, no blockage and working properly.
