My skimmer has little to no suction on it. First time pool owner and just opened the pool up this weekend. Seemed like everything was working fine at first, I was able to vacuum the pool with no issues. After that first day I wanted to vacuum again after the pool party we had for my son the day before, lots of sand a on the floor. Hooked up the vac, and nothing. Checked the skimmer, there was very little suction. I remember the day before it had a little swirl and was slowly pulling things down into the basket. I turned off the pump and checked the basket there. Well it was very dirty. I cleaned it out popped it back in and started the pump back up and started to vacuum again. I was doing OK for a bit, but then it just stopped picking up again. Decided I was going to stop and try to figure out what was going on. Started to pull the vacuum hose out of the pool, and lost most of the sand that I sucked up, fell right back in the pool out of the vacuum hose! One thing I noticed is if I stop the pump and restart it, there seems to be a little suction at the skimmer, but it slowly fades to next to nothing. Any ideas?
