Draining pool

[svtcobra]

First off thanks so much for everyone that's helped me out so far.

The submersible pump I bought has worked like a charm.

now that I have the pool drained this far I plan on sweeping out as much leaves as possible and buying a leaf vacuum for the deeper end.

a pool company was supposed to drain the pool for me and they told me that they would put muriatic acid on the walls in power wash it.

Should I go ahead and apply muriatic acid? Then power wash? I plan on draining more water out of the pool how long can I leave the pool with minimal water while I do the cleaning of the walls? Also sorry last question are the tiles and anything else just cosmetic or do they need to be replaced in order to have a functioning pool?

Looks like you have a bit of a project on your hands. I'll open-up the discussion and let another expert like @bdavis466 give his 2-cents worth. Your pool appears to have a few years under its belt. You want to be very careful about power washing the aged plaster. In addition, with a while shell, I don't really see the need to apply acid to the shell as that could weaken or etch the already aged plaster. Perhaps just a good chlorine cleaning? As for the missing tile, while serving primarily a cosmetic function, it could also help to keep water from seeping behind. The gunite behind seems to be solid, but I doubt it should be exposed to water continuously. As for leaving the pool empty, that's always a risk. I don't know your area's typical water table, but if it's elevated the risk increases, so be careful. If you skip the power washing and acid stuff, you might just refill and do a SLAM Process to clear that green and just let chlorine do the rest. But enough from me, let's see what our plaster expert has to say.

This sounds great to me...one thing about me is I'm patient and persistent so looking forward to making this pool work.

Thanks for confirming it's plastered. I wasn't sure of the material.
