I've had air in my pump basket since I bought the house with the inground pool 2 summers ago. It's a livable problem right now but it does have it's draw backs. Firstly, I have to blackwash the filter about every 1.5 weeks to remove the excess air built up in my sand filter (otherwise the air pressure in the filter blows off the skimmer lid when pump is shut off). This is not a long term solution as it can sometimes jam the floating weir and potentially cut off water supply to the pump when it does come back on. I've changed o rings and flooded the pump and fitting areas with water without a change to the amount of bubbles in the pump basket. Note: This is an older balck poly and barb fitting pool system. My strong feeling is it's the connection to the skimmer port in the ground as it's likely a barbed fitting too. Fortunately the area around the skimmer is interlock brick, gravel and dirt so I don't have to break up the concrete.
Has anyone been in this similar situation? I've checked the skimmer and there does not appear to be any cracks. I want to do this myself as digging isn't a problem or repairing the piping.....and I would like to save some money.
Thanks for the help!!
