First post here--have learned a lot from this site, and appreciate all the generous advice I've been reading. Did a search but couldn't find this exact topic.
I should preface this by saying I'm currently in the middle of a bacquacrap to chlorine conversion, in case that makes a difference. I'm having a problem with my pumping system that developed at the end of last season and still remains.
I'm getting poor water velocity from my return line. It's probably about 30% of what it is when the pump is working well. Here's what I've tried, and the results.
--"Bypass to pool" produces slightly better return rate out of the return line, but still, at best, half of what is should be if the system were working well.
--Backwashing and rinsing send very little water out of the waste line. The water velocity is so poor that it's barely enough to push water through the length of the waste hose.
--Filter is not running well enough to get the vacumn to work for more than a minute or so at a time, and then very poorly.
--Bypass to waste works much better, as far as water velocity from the waste line (I'm still not convinced it's 100%, but it's much better than "backwash"), but for some reason I can't get the vacumn to work at all when using this option.
Sand is brand new. Installed along with clean laterals two days ago. When I emptied out last season's sand, it had green algae in it, and the old laterals (I've got two sets--long story) were plenty clogged with green gook. But I'm having the exact same problems with these clean laterals.
Think my pressure gauge is busted, but it reads 40 when filter is off, and 45 when running.
Any ideas of what I might be dealing with here? Thanks in advance for whatever wisdom you can offer.
