I have been thinking about draining my pool. It's concrete and made in the 1960's. From everything I've been reading, draining a concrete pool is bad because of the possible up heaving. My question is, can I drain it half way without worrying about this happening? It's 8ft at the deepest part, and 3ft in the shallow end. I would like to drain out the shallow end and pressure wash the sides.
I've already tried chemicals, brushes, nets, and needless to say, it has cost me hundreds already with no real results. It's been green for over a year now, and the frogs and water beetles call it home. I can't access the drain at the bottom cause I can no longer see it. And I'm sure with all the decaying junk at the bottom, it's blocked anyhow.
Only thing stopping me from just calling it quits with it completely and filling it in is, it will lower the value of my house by $6k.
