Im baffled having small jet stream bubbles at the pool jet return. Very small bubbles like champagne sized also it sounds like gargling sound at the jet return. Is this a plunger problem. Things i have tested I have checked the skimmer pump basket o ring looks good no cracks or visible damage. Checked the drain caps no problems on them. No leaks all equipment is tight have took hoses apart at all sections into pool and drained water back into pool made sure hoses were fitted tight no cracks on o rings on pump in great shape. Have tried back washing to allow if air is trapped to come out. So far nothing has worked. Just wanted to no would these bubbles cause any problems as pump is working solid no issues with water pressure.Skimmer basket is full of water prime is working fine.
