No Suction 2.0

[Nashvillejoe]

i have a similar issue with the previous "no Suction" posting.

my pump just stopped sucking water- in the middle of the day- its a 2HP Hayward Northstar.

here is what i have done....

1) removed the basked from the skimmer and used an auger 20' in to make sure there was no clog
2) cleaned the pump filter and attempted to clean impeller ( no visible debris)
3) disconnected the large filter and augered the lines around pump (all clean)
4) cleaned the pleated filters
5) i have opened the lines to and from pool.... water seems to flow easily in both directions- with the top off the filter and valves open, the filter will fill with water from both the skimmer side and the jet side- so i am ruling out a clog/backup
6) i believe the pump while it runs and mechanically sounds normal, is not pushing water with enough pressure to move through the system

it appears the seal on the pump filter is tight but i ordered a new on and will pop it on as soon as it arrives.

it appears the pump is just not pushing water but it sounds completely normal when i am running it- if i open the air release on the filter it is pushing very little air and the air coming out sounds a bit like a 8 sec saw tooth wave..... WHISsssssssssssssssssssssssssWHISHssssssssssssssssssssssWHISHsssssssssssssssssssssss

oh and the pressure gauge on the filter isn't reading any pressure

the pump itself is probably almost 9 years old......... is it worth troubleshooting or is it time to invest in an upgraded pump one of those multi speed guys that save money ???

thanks in advance for the help!!

It sounds like there could be a suction leak and the pump isn't priming. More here, Pool School - Suction Side Air Leaks

+1 what pooldv said........suction side leak. Do you have enough water in your pool? Is it sucking air down through the skimmer?

thanks- i actually did order one of the kits which include all O rings etc- so that was going to be my next move- also ordered a new impeller- i figured if we have to open up the pump- might as well go ahead and replace it.

no problem with the water level- its actually not pulling anything through the skimmer- soooooooo if the impeller is still intact- there must be a supply side leak!

thanks again!
