How to maintain a swimming pool over winter

  1. 1. How to maintain a swimming pool over winter A quick no-nonsense guide http://www.aspectspools.co.uk
  2. 2. 1. Chemical Balance • Balance the water pH between 7.2 – 7.6 – Use testing strips (cheap and easy) • “Shock” treat the water – Raise chlorine/sanitiser to higher levels for a short period – 20 parts per million – N.B. this is NOT a safe level for swimming – Remove the nitrates and organic residue this will leave (usually at the pool bottom)
  3. 3. 2. Clean, clean, clean! • Brush the walls – Remove any residue or build-up on the pool walls • Vacuum the pool – Pool “robots” make life easier! Time spent in cleaning the pool will pay off when it comes to re-opening it in spring.
  4. 4. 3. Algaecide • Add an algaecide – Acts differently to Chlorine to effectively kill algae – Reduces and inhibits algae growth – Makes chlorination work more efficiently – saving you money and using less chemicals No algaecide = green pool in the spring!
  5. 5. 4. Mechanical Drainage • Drain down the pool – Reduce water levels to 6 inches below the skimmer – this reduces water freezing risks Backwashing the sand filter to “waste” is a hassle-free way of doing this. Do not drop levels lower than this – you can risk damaging the pool liner or shifting the surround.
  6. 6. 5. Decommission • Turn off electrical equipment – Switch off or isolate electrical sources • Drain the pipework – Protects against frost – Drain the pump, filter, heater and all exposed pipework – Useful tip: Keep the “O-rings” in a jar or zip-lock bag to prevent perishing.
  7. 7. 6. Lastly . . . • Remove any equipment – Keep ladders, boards, slides safely stored and out of the way of the weather • Cover the pool – Check the cover isn’t damaged – Make sure it’s fixed on securely (stormy winds and child safety)
  8. 8. Pool covers – Reduce leaf litter and biological debris: less growth media for bacteria and algae – Cuts down light for algae build-up – Reduce evaporation and mineral build-up: maintains water balance – Long-lasting if looked after well: consider using a reel to look after large covers Check for damage! They do wear out
  9. 9. Measuring a pool cover: – Depends on pool shape: measure largest “rectangle” and add in additional areas
  10. 10. Choose material and fixings – A cover is only as good as how it’s secured . . . The UK has experienced sever winter storms recently – Anti-chafing straps will stop damage – Ensure nothing (or no-one) can crawl underneath Safety first! Even safety covers are not designed to be walked on. Always ensure children and animals are supervised, even near a covered pool.
