How often should you drain an inground swimming pool if it is kept running year round?
The only risk is if you drain or try to drain a pool after prolong rains or is you are aware of how high the “water table” is in your area. In order to get that info you may have to call your water district and ask them. “high water tables” make draining a pool a dicy situation. The result of an empty pool during these conditions is usually a pool that will float out of the ground. It will act like a bath tub or a boat …even if it is made out of steal reinforced cement.
