We've recently started doing our own maintenance & the local pool supply says we are very high on cyanuric acid. Their recommendation was to add water for 8-12hrs. Rather than have that much water draining down our street from the overflow, I'd rather drain some water & then add fresh.
Problem is I don't see how to do that. I'm not even sure we have a drain other than the overflow. We have a septic system so unless it drains to the storm sewers, we may not. Can you tell from these pics how the pool is supposed to be drained? Maybe by hooking up a hose to the faucet that's above the pump?
