First Post. I recently purchased a house (45 days ago) that has a pool. I have had pools before but only when I was younger and lived with my parents. Alot of this stuff is coming back to me but..... slowly. I got a couple questions and hope someone could help me out. #1 I have a main drain but there is no flow or suction in it. Iwas under the assumption that is how most stuff gets sucked into the sand filter. Question #2 I lose pressure and prime EVERYTIME I vacuum the pool. It takes me about 3 hours to vacuum since I have to disconnect from the skimmer, wait for the pump to catch up, start vacuuming again. I wish I would have found this site a month ago its got great information!
