This is my first "real" post here.
I'm a new pool owner. We just bought this house a few weeks ago and I'm finally getting around to stabilizing the pool water.
The previous owner must have been a fan of Trichlor because the CYA levels were off-scale HIGH on my La Motte ColorQ tester. This is mostly verified by cutting my test water sample by 1/3 pool water and 2/3 tap water. After one partial drain and fill, I am down to 105 ppm CYA.
This is a vinyl in-ground pool, 30,000 gal. and I just added an Intellichlor IC40 SWG. I have a sand filter with the standard Hayward rotating lever valve. I have no diving well main drain, just one skimmer intake. I've drained the pool to about 8 inches below the skimmer line.
My question is, are there any settings I can configure such that I can leave the hose running into the pool overnight and not overflow the pool?
My property is easily 20-30 feet above the street and the waste line runs down to the storm drain underground.
If I open the waste line and leave pumps and SWG turned OFF, will gravity take care of overflow via pressure on the open waste line and discharge down the property to the storm drain?
Many thanks for your time and opinions!
