Whether you live in the sunbelt or the snowbelt, closing your pool correctly is an important and easy process that will elongate the life of your swimming pool.
- Adjust pH to 7.2-7.8 to prevent stains, scaling and algae growth. Shock the pool using label directions.
- Run the filter for 24-48 hours.
- Remove floating debris and vacuum thoroughly.
- Add an algaecide to prevent algae from forming before water freezes.
- Follow your swimming pool manufacturer’s directions for lowering your water level. Only a few pools need to be completely drained during the winter. Many pools fare cold temperatures better when partially filled with water as a buffer. A drained pool can also crack or pop out of the ground because of pressure from ground water.
- Shut off filter pump and drain pump, filter heater and all other equipment. Store to prevent freezing. Follow manufacturer’s directions for lubrication and proper covering(s).
- Turn off all power to the support equipment, then remove fuses or turn the circuit breakers to off.
- If you have a slide or diving board, take it off and store it.
- Cover pool securely and fill water bags halfway (the edge of the cover should be sealed so that wind does not get under it). A quality pool cover resists water, weather and pool chemicals and keeps out leaves and airborne dust.
Your weather permits a longer swimming season. However, if there will be many weeks when your swimming pool is not in use, continue routine maintenance on a reduced schedule.
- Begin by reducing filter running time in half. Keep pH between 7.2-7.8 and free available chlorine between 1.0 and 3.0 parts per million (use tester). Follow pool equipment manufacturer’s instructions for proper care of equipment during this time.
- If you do not cover your pool, clean your skimmer every week, maintain filter according to manufacturer’s instructions and vacuum as needed.
- Covering your pool will keep out leaves and dirt and reduces the number of needed chlorination. Before covering, shock treat according to manufacturer’s directions.
