Can You Shock a Swimming Pool When the Pump Is Not Running?

Shocking a swimming pool requires no special skills, other than the ability to read the instructions on the chemical you have purchased for shocking the pool. Often, over the winter, the water in unused pools drops below the level of the skimmers and becomes fouled with algae and dirt. The system's pumps won't be running either, but you can't shock the pool without the pumps circulating water.

Preparation

Remove any pool covers and begin adding water with a hose to bring the pool's water level back up to normal levels.

Treatment

Add shock chemicals per label directions as the water level rises. The hose will cause the water to circulate within the pool.

Maintenance

Use the net to remove leaves and trash and the pool hook to remove larger objects. Empty the skimmers.

Circulation

Turn on the pump using regular startup procedures as soon as the water fills the skimmers.

Completion

Complete the shocking process as explained in the chemical instructions. The water should clear in a few hours.

Warning

When mixing shock solution always add the solution to water. Do not pour water onto the chemical. Always wear gloves and eye protection when handling pool chemicals.
