Winterizing Procedure for In Ground Swimming Pools

Winterizing Procedure for In Ground Swimming Pools

Chemicals Required:

  • Dry Acid/Alkali
  • Shock Chlorine granules
  • Long Life Winteriser
  • Liquid Chlorine
  • Ensure pool is clean and clear.
  • Bring pH to 7.4 to 7.6 using Dry Acid or Dry Alkali as necessary.
  • Super chlorinate the water to 10ppm using Shock Granules or Liquid Chlorine.
  • Add 1st Direct’s Longlife Algeacide. (2ltrs will treat 11,000 gallons).
  • Keep pump running for 8 hours to disperse chemicals thoroughly.
  • Periodically through the winter, check the pool, ensure the pH is between 7.4 and 7.6 and the chlorine level is above 5ppm.
  • If chlorine level is low add Liquid Chlorine and stir pool to ensure even distribution, as concentrated areas of chlorine can cause bleaching of the liner. The pool should especially be checked after Christmas and around March as most pools go green when the ambient temperature starts to rise

1st direct Winterizing Program

  1. Never empty pools for the winter.
  2. Thoroughly backwash filter and lower the water level to below the skimmer weir; the only exception to the rule being pools installed in high water table areas, where lowering the water level could cause problems. In these circumstances, consult the original builder of the pool.
  3. Store summer covers clean and dry during the winter and fit winter cover.
  4. Store vacuum equipment and automatic cleaners indoors.
  5. Remove skimmer weir and basket and store in filter shed. Half fill plastic bottle with anti freeze mixture or small stones and place in skimmer barrel to prevent ice damaging the skimmer.
  6. Add winterising chemicals and allow to circulate.
  7. Make sure the filter, pump and heater are drained down for the winter and all exposed pipework holding water. If the filter is positioned below water level, seek further advice from the experts by simply clicking on ‘contact 1st Direct’.
  8. Spray the electric motor and any electrical equipment with a moisture repellent spray or preferably remove pump and store in warm dry conditions. Switch off electrical equipment.
  9. If heat pump is fitted flush with clean water.
  10. If auto chemical feeder is fitted, remove chemical and flush with clean water and leave drained.
  11. Remove all stainless steel steps, rollers etc and wipe clean and store in dry store.

If we experience a particularly hard winter, 1st Direct suggest the following especially for concrete pools: tie a row of half filled plastic containers (fill with an anti-freeze solution or sand) along the middle of the pool. This is to form a frost break to relieve pressure of ice on the sides. Formed ice should not be broken, as sharp edges may damage the pool lining.
