Have 23inHg suction on my 1.5" line.
It seems like I've tried everything (ha ha), but have failed so far.
Have 1.5" PVC adapted up to 2" at pump inlet.
First, on pump inlet side I've tried:
Water hose with two sizes of "Drain Kings" run at least 20 minutes.
Water hose wrapped in towel run at least 20 minutes.
1/4" & 3/16" snakes - but couldn't get past bends to main line.
Never saw anything come out.
At skimmer side I then tried:
1/4 & 3/16 snake - but couldn't get to main line either because of bends or blockage.
3/16" got the furthest. Once, previously, like 2 feet in. Today only maybe a foot.
I'm pretty convinced the blockage is next to the skimmer as today's snaking has made the blockage significantly worse! Vacuum gage at pump now at 25inHG from 23 before today's snaking.
This was to be my final attempt at this, so of course, today's attempt is the first time it did anything and it made it worse!
So now I'm pretty screwed.
I'm aware there is "art" to driving a snake, but am apparently, artless.
Any suggestions on how I proceed?
