Hi,
I want to raise the water level of my pool to where the calcium line in the first picture is. However, I was adjusting the autofill valve and noticed a hole just behind it that's half filled with water. Is that an overflow drain?
I'm worried if I raise the water level it might just drain away through that hole. It's strange that the hole already has water in it, even tho the pool's water level is currently about 3 inches below the pool main overflow drain, shouldn't they be level?
Thanks,
Roger
