I have a 15 x 18 concrete pool that is about 25 years old. We are going to give it a much needed paint job this spring.
As a few weeks ago we noticed the pool lost about 1/2 of its water and we had absolutely no issues over last winter with water loss.
For the life of us we cannot locate our hydrostatic valve when it comes time to empty and paint the pool. Is it possible that the pool does not have one and if not, what are our other options?
Thank you for any information you can give.
