My Sta-rite 2hp pump recently died and I have not been able to replace it due to recent hospitalizations and disappearing pool suppliers or suppliers who do not carry my preferred brands. My pool water has turned an ugly shade of green and is supporting some new form of life. I want to drain as much water as I can safely. During the building process some ten years ago, the City required the builder to use rebar 2.0. I wish now I would have taken a picture. So much rebar. So, after draining, I will need a new variable speed 2hp+pump, SWG system, and control equipment. What is the latest recommendation for the draining process? I like Pentair equipment. I have had two Taylor test kits and scores of reagents. The pool is around 27,500 gallons with a Pebble Sheen surface. Any opinions as to how I should drain and re-build are appreciated. BTW, I am headed back to the hospital again, and again. Looks like I will have to visit Leslie's...noooo.
