INLINE LAKE FILTER
My sprinkler sytem is fed from the lake. I have a filter at the lake side which appears to be very dirty. I can't get the filter casing to turn so I can clean or replace the filter. Is there a special tool? Also, I started up my system and one zone seem to have a valve stuck and runs until I turn off the pump. Does this mean I might have debris in the valve?
Thank you for your help.
