    Default Low Pressure

    I've noticed my filter pressure is running lower than normal. Typically the min, pressure I would see is about 12PSI. Currently it's running at about 8PSI. I know a dirty filters causes higher pressure, what causes lower pressure?

    I've been trying to track down the source of bubbles in my return lines as well. Could these be related ?

    Could be as simple as something gummed up BEFORE it gets to the filter. Your pump may be partly clogged.

    Sir, you are GOOD.

    I pulled the strainer before the pump and stuck my fingers down the pipe and sure enough there was leaves and stuff all over the blade.. Pulled them out and now it is back to typical PSI...


    Thanks for the assist!!!


    Has anyone ever figured out what happened to Ben ?

    You are very welcome. I'm just glad it was that simple--and cost-free.
