Just joined the forums, I have been reading them for advice since I became a pool owner a few weeks ago and they have been extremely helpful. I am currently a noob when it comes to pool knowledge, but I hope to slowly correct that : ) So there was a lot flow/bubbles going on in my pump basket looked like a rapid river in there basically and from everything I have read.. it should be pretty still looking air tight water. So I figured there might be air trapped somewhere so I turned the pump and pool off, opened up the pump basket and added some lube to the o-ring. I also, while the pump basket was open, opened the air valve on top of the filter to bleed the air out of the system. It is a Pentair DE Salt Water Pool system, 15,000 gallon pool and I think the filter is a 60sqft. Anyways, when I opened up the air to bleed it out, water started coming up out of the pump basket and overflowing for as long as I bled the air. Is this normal? Any ideas what is going on? Maybe its simple, but like I said, I have a lot to learn! Thanks for any and all help everyone.
