Hi Folks - I had a new above ground pool installed about a week ago (see signature for pool/pump/filter specs). Since day one, I have had large bubble(s) in the pump basket in the lid. I run the pump on the low speed setting about 10 hours a day and the pool is crystal clear. Running the pump on high speed for about 15 minutes seems to reduce the number of air bubbles to the point where if I turn off the pump, one large bubble will form under the lid about 4" in diameter, but that bubble remains regardless of how long I run the pump.
The pump has held prime over night.
All my plumbing is hard piped 1.5" PVC and I checked every valve, union, etc. from skimmer to pump inlet with no visible signs of a leak. Each connection was sprayed with a soap solution in an attempt to see if any air was finding its way into the line on the suction side; nothing was detected. The pump basket lid is not cracked and the O ring has been lubed and I have also checked pump drain plug (O ring is fine and lubed). I tried the plastic wrap method around the pump inlet union and shaving cream trick, no discernible water or air leaks.
The Hayward 2 speed 1HP pump is brand new (model SP15922S)
The Hayward Sand filter (300# Model S244T) I purchased used off of Craigslist.
Last night at around 9pm, I switched the pump from filter mode to recirculate and ran the pump on high for about 5 minutes. BINGO - all bubbles in pump basket went away within 5 minutes. I turned the pump off, went to bed, and this morning at 7am returned to pump with the basket completely full with no air bubbles.
So, why cant' my pump get rid of the air bubbles in filter mode? Is there a "rebuild kit" available for the multi-port valve where I can replace O rings, etc. if that is the problem? Is the multiport valve the problem?
FYI - on low speed, I get a sand filter pressure reading of 4 psi; on high it reads 18 psi. All of the sand in filter is brand new and I ran the filter to waste, and then rinsed before running and filter mode (wanted to get any PVC shaving out of of the lines b4 running in filter mode). The pool was filled with "city water" (i.e. same water that supplies my house),
Any insight into the above issue would be greatly appreciated.
Thanks,
Greg
