Swimming Pool Chemicals
Cold weather causes water to freeze and expand, adding the risk of damage to any materials that house or come into contact with water. The piping, filter and pump of a swimming pool all share the risk of freezing damage during the winter months in any area that experiences freezing temperatures even just once a season. Draining the water held in a pool removes it from the majority of the pool’s plumbing, eliminating the risk of pipe breaks or freeze damage to the pool casing.
A. Turn the pool equipment off. Rotate the large handle located on the filter’s dial valve to either the “Waste” or “Backwash” setting. Both settings cause water to exit the pool via the waste or backwash line.
B. Turn the equipment on. Run the pool until the water level drops to a point just above the bottom of the skimmer. The filter pulls water through the skimmer and “maindrain”; when the water level reaches the skimmer’s lower lip, the pump sucks air due to the fact that water is no longer draining through the skimmer.
C. Lower a sump pump partially into the pool water if further draining is required. Place the pump’s drainage hose at a suitable drainage area, preferably downhill from any working areas or neighbors’ developed property.
D. Run the sump pump until the pool drains to the level you desire. Use multiple sump pumps if the pool’s volume of water is large. If the pool requires complete draining, periodically lower the sump pump further into the pool water as the level drops.
