Hello - have a 36x18 liner pool with attached spill over spa. I am trying to figure out if my water loss is due to a leak or normal evaporation. I did a bucket test and over a 36 hour period my pool lost just about a 1/2 inch and my bucket lost 1/4 inch. I have a spill over spa and was told that i will lose more water due to the spill over but doubling my bucket loss seems high to me. If anyone has any insight it would be greatly appreciated. I love in New England. Pool company is coming over today to check things out but wanted to get some additional information before they arrive. thanks in advance for any input!!
