Hey Group, I ran a search on this and came up empty so sorry in advance if this has been addressed. My Flowtec 1hp pump has a significant amount of air in the top. I have changed the o-ring once on it and tried to lube the o-ring before tightening but no luck. My old Wayne pump that this replaced did not have any leakage/bubble issues. I'm just wondering if this is common with the Flowtec pumps? It also "burps" about a 1/2 a cup of water when the pump is turned off.
Thanks in advance for any suggestions.
