So my pool was running fine for several months until last week, had sudden loss of pressure at the filter and rattling noises in the pump basket/ motor area.
Previously running 22-24mmHG, now it dropped to 5-7/
OUtput has been less than half of its usual.
I tried flushing the skimmer suction line with a towel wrapped hose, at the pump end, and water seems to be running fine back to the pool,
Opened up the motor to check the impeller and its not clogged.
No breaks in any baskets.
Also does not have enough backpressure to run the vacuum cleaner line, unless I divert all the output to that extension,
I tried putting some shock in the skimmer line overnight to see if I could expel any organic material this morning and that was no go.
I called a pool troubleshooter over to check my lines and he said he couldnt do much more for me after looking at my system, suggested to keep the vacuum running to decrase back pressure and extend motor life.
I never use the vacuum as I run a pool robot.
I have a small dribble coming from underneath the pump basket area, but see no obvious cracks otherwise and cant tell exactly where its from.
Just short of calling roto rooter to scope my intake anything else Im missing.
