Moved from this old 2018 thread.. Hayward Pump VS900 not filling basket
EDIT: Sorry for posting on such an old thread... just seemed like all the steps I've already tried were listed on that thread so it seemed reasonable and didn't want to waste anybody's time. Here's the link to the old OP's video which basically shows the same issue I'm having:
Well, this is an old but interesting thread... for me. I've got the same exact issue with my Hayward Tristar pump (my water thrashes a little harder than the OP's in his posted videos) and I've tried just about everything to fix it without any success. I actually just bought a new pump lid, with new o ring (and lubed it)... but nada.
Pump doesn't drain when not running, it actually fills up a tad bit higher than when running and just stays there until I run the pump again. Can't be an underground plumbing leak causing this as I have 3 different intakes I've tried separately (skimmer, separate vacuum line, spa). I even removed the guts from the check valve pictured in case this was causing any king of a flow issue.
I've had my own thread discussing this last year, and have since replaced the filter which I know shouldn't have any effect on this anyways... but yeah, was actually considering to replace these 2 45's with a 90 sweep and new pump union on the intake side.
Anyone think there's a chance of that improving the flow enough to fill the basket? Cause after that I'm completely out of ideas.
