I just bought a house with a pool about a month ago. All seems well. I had some challenges vacuuming the bottom of the pool. Skimmer adapter plate was missing so I was just pulling the basket and sticking the hose down in the hole. I bought a skimmer adapter plate and the vacuum wouldn't work. After reading a few posts here and brainstorming while staring at the plate I realized that I had cavitation. The hole in the plate was about one inch. is I drilled out the plate to match the hole in the skimmer and it works good now.
That's why I came here.
Now, why I am here now.
I've been taking samples to the pool store and buying whatever they tell me to buy. 💰💰💰💰💰 I'm spending about $50 a week. Sometimes more and sometimes less.
