How Do You Drain a Swimming Pool?

To drain a swimming pool, connect a pump and a hose to the pool and drain the water into a sanitary sewer system. Alternately, dechlorinate the water before draining it into a storm sewer.

Due to the chlorine content of pool water, it is important to drain swimming pools properly. Some cities, such as Washington, D.C., even have laws against draining pool water improperly. To safely drain a swimming pool, run through the following steps.

  1. Source a pump
  2. Some companies rent sump pumps out to homeowners who wish to do pool maintenance. It is important to choose a pump that can work underwater.

  3. Attach a hose to the pump
  4. Attach a hose to the pump.

  5. Find a safe drainage source
  6. Sanitary or combined sewer systems are appropriate places to drain pools as these systems are designed to treat wastewater. Private septic systems and storm drains are not appropriate places to drain pools. If there is no alternative to storm drains, dechlorinate the water before draining the pool.

  7. Submerge the pump
  8. Once the drainage system is connected, plug the pump into an electrical source, submerge it under the water in the deepest section of the pool, and turn it on.

  9. Monitor the pump
