So the house I bought has a wonderful pool, but since it sat idle for three months between when the sellers left and we bought it, the pool water looks like it needs to be changed out. CYA over 100, PH over 8, that sort of thing.
Good news is the hayward vari flo valve has both a backflow ( so I can clean the DE filter which probably needs it ) and a Waste setting which is piped to sewage. YAY!
Bad news is it looks like the main drain was disconnected as the 1 skimmer I have features a return to the pump and a second port on the bottom which I would expect to go to the main drain.
But there is no suction whatever on the main drain line, so I figure it was disconnected as the pool might be as much as 30 years old ( relatively recently remodeled pebble tech at least )
My plan would be to use a vacuum hose to extend the skimmer suction to the bottom of the pool and 'waste' away.
Given that I am in Phoenix and up on North Mountain a bit, I dont figure a high water table will be an issue ( although we did just have 3 " of rain last weekend so I will be waiting till next weekend to do this drain )
Still. Once I figure out an actual CYA reading, and a reading on the unfortunately hard water that I will be adding in to the pool from the tap
I should have a much better understanding of how much of the water will actually need to be removed before I can start filling it again.
My question is : aside from ensuring that I maintain a good seal at the vacuum/skimmer attachment (probably by leaving a garden hose running a little water into the skimmer, is there anything that I am forgetting?
Thanks in Advance,
