Hi...I am a new owner of a below ground pool.
It has a cover.
I turned down the heat and left the pool running all winter.
I discovered the pool level drops as much as 1.5 inches per week.
I put a large container of water in the pool on the step...the water in this container did NOT touch the pool cover on top as the pool water does. Of course, the container water isn't passing thru the pump system.
The container water dropped maybe 1/4 inch per week.
Now that it is warmer outside, the pool water is dropping by 1/2 inch more then the container water----less then during the winter but still something.
Do I likely have a leak or is the pool cover touching the water and the pumps causing the extra water loss? Inquiring minds what to know!!!
