Swimming pools are designed to hold water at all times. The only time to empty a pool is for the purpose of renovating.
In the cooler months of the fall and the cold months of winter it is important to maintain the proper water level in the pool. If your pool is operating throughout the year or has been winterize it is always important to check the water level often.
If it appears to be leaking contact Chris Tally at NPS Leak Detection to have your pool tested for leaks.
