So, this is my first post, but I've been reading this site since I bought a house with a pool last summer and it's been absolutely invaluable. Can't believe the amount of money I wasted and bad advice I received at the pool store before finding TFP.
Anyway, I'm wondering if the following is normal- when I shut off the pump and remove the cover from the basket filter to clean the basket, the water in the basket starts to drain and I hear loud gurgling noises. I assume at this point air is entering the sand filter. The noise stops after a few minutes.
After cleaning, I put the basket back in, fill with water, put the cover back on making sure it has a good seal. I turn the pump back on (filter mode) and everything works except one of my return jets spits out a good amount of air bubbles for 2 to 3 minutes.
After that 2 or 3 minutes, everything settles down, no more air bubbles and everything seems to be running clean. Just wondering if this is something to be concerned about, or if all systems work this way.
