Hello and thanks in advance. Im at my end, I just bought a house with a pool and iv spent most of my time getting the pool/spa to operate at 100%. My latest problem is that the suction is too low to operate the new Hayward pool VAC I just spent $400 on .
Here is what I have and know:
-Pool is about 25k gallons
-Hayward filter with 24" grids
-vacuum hose operates from skimmer
-pressure is at 15 normal and gets to 19-22 before backwash.
-two inlet ports one from pool and other from spa drain (I cant tell where the pool main drain is as the is only two options for water to come in)
-two outlet ports one to pool (Which splits to two holes on pool wall where water returns) and the other to spa.
-1 HP pump
- 1 1/2" pipes
- all new grids in filter
-new backwash valve and assembly
-pressure is at 15 with filters completely removed (did this to check for filter problems)
Ok so heres my problem, I just bought a new Hayward pool vacuum and the suction is too low to operate it, it just sits there. It came with flow gauge and on the gauge it has "Max and Min" window to check flow and when i hook up the hose it reads below the min by far. The suction on my hose is comparable to a shop vac or less.
Heres what ive done so far, i got my shop vac and used it to suck out anything from the skimmer port where the vac hose attaches to and nothing came out. I completely took apart the filter, grids, manifold etc and cleaned it and inspected it. Iv verified that im using the correct amounts of D.E. and chemicals. And now I'm at a loss. My thoughts are that my pump is bad but I used a mirror to check the impeller and its fine, I think i might need a stronger pump and if im going to go that route then ill just go with a variable speed........Please Help!
