Winter Evaporation with mesh cover

JohnT,

All the valves and equipment are above the water level of the pool.
I guess I'll have to hire the pool guy again to do some leak detection work.

Thanks for your advice.

John,
Some questions for now. Do you know if the water level stabilized at 2" at the shallow end? All your plumbing should be above that level unless you have a main drain. If you don't have a MD then it's a liner leak or....how about stairs into the pool. A common leak area is the pinch of the liner around the stair opening. In my opinion the first step in your case would be to fill a few inches and see what happens. Measure the depth accurately at some known point to be able to estimate a loss rate. Depth change x surface area to yield cubic feet per time then gallons per time. Then we can go from there. 'Typically' the greater the depth to the leak, the faster the water will leak. Eventually stopping at the depth of the leak. Last year I developed some techniques on finding and repairing leaks for my own problem.

Al,

I'll give that a try. Yes, I think we're stable at 2" in the shallow end. I do have a Main Drain, but I have to agree - The area around the steps deserves a second look.

Thanks for your help.

your problem is completely different than my concern but i thought this wasn't a bad location to add a question ...

this was our first winter with a similar safety cover. when the cover was removed the water level was "right on" -- almost zero water needed to be added or removed

sounds great but this spooked me ...

what if the water level got to that level during the winter, froze and had cracked my lines? is this a concern that anyone else has with these covers? do you check water levels at regular intervals during the winter?
