This procedure covers the main processes, however every pool is different so please consider the pool you're closing and the associated equipment.
- Clean solar cover and roll up. It is advisable to protect the cover from UV by either storing in a dry barn/garage or wrapping it in a solar protective sheet.
- Vac out all leaves and debris - left in the pool will rot down and stain the liner/grout or plaster finish. If the pool has a designated Vacuum point then we would recommend vaccing the pool too waste rather than filtration as this will reduce the pool levels at the same time.
- Backwash filter thoroughly to remove dirt which should not be allowed to overwinter in the filter
- Lower water level to 6-10" below the skimmer - ensure skimmer and vac valves are closed when reducing the levels.
- Shock dose with Calcium Hypochlorite or Sodium Hypochlorite - seeking <10ppm
- Adjust pH to 7.2-7.4 to maximise efficiency of shock chlorine
- Add winterising algicide
- Float weighted plastic drums/bottles in middle of pool. These act as a buffer should thick ice foams.
- Remove steps and skimmer baskets
- Fit winter debris cover (WDC). These are essential in reducing wind brown debris getting into the pool and reducing UV light breaking down the winterising chemicals.
Cris cross debris cover correctly installed - Drain down filtration, heating and pipework systems. A number of customers are now protecting their heaters by insulating or wrapping them in a protective sheet
- Grease all exposed metal surfaces with petroleum jelly to prevent rusting
- Drain pump and spray with water repellent or store in dry location
- Open all valves above water level and close those below
- Switch off auto top up (if present)
- Switch off main electrical supply to pool equipment
We hope this procedure is of help. It is common for customers to ask their local pool business to complete this procedure for them.
