    Persistent Pressure Increase and Need to Backwash

    Hello All! I'm new to the forum and any help is greatly appreciated. I have a 30' above ground pool with a Jacuzzi filter and 1hp pump. I'm having trouble with the filter building pressure every 4-5 days requiring me to backwash far more often than I expected or had to last season. When I backwash the water seems to flow clean. We have a very clean pool.. it sits out in the open and rarely gets dirty. Can anyone shed any insight as to why I'm having to backwash as often as I am? Thanks in advance..

    Welcome to the forum.

    Everything about Pool water chemistry begins with a set of test results so we can determine the condition of your water.....can you post those?

    Welcome to TFP!!!

    If the pressure is rising, then the filter must be catching something. Even if the water looks clear, you could have a low level algae bloom that is clogging things up. Thus, the reason Dave is requesting test results.
