Whether you plan to keep your pool running over winter or close it down, a few careful steps now will save time, money and repairs in spring.

Quick checklist

• Deep clean & remove leaves/debris
• Test & balance pH, alkalinity and sanitiser
• Shock the pool and add a winter algaecide
• Lower water level (if closing) and drain plant equipment
• Fit a quality winter or safety cover and tension it

Step 1 — Clean the pool thoroughly

Remove leaves, twigs and any surface debris. Brush walls and floor to dislodge dirt and algae spores, then vacuum and backwash or clean your filter until water is clear. A clean pool is the simplest way to avoid winter problems.

Step 2 — Test & balance the water

1. Adjust pH to the ideal range (generally 7.2–7.6) and set total alkalinity to manufacturer guidance.
2. Shock the water with a full chlorine dose (PoolStore recommends raising free chlorine to a high level for distribution before winter products).
3. Add a long-life winter algaecide/winterising product to prevent algae growth while the pool is less active.

Distributing chemicals with the pump running for several hours helps them reach the whole pool volume before you reduce filtering or close down.

Step 3 — Decide: active winter management or full winterise

Two common approaches:

• Active winter management — keep the water in the pool, run filtration on a reduced timer (for example short, regular cycles) and perform occasional checks. This avoids refilling and is often eco-friendly and cost-effective in milder climates.
• Full winterise / close down — lower the water level (typically ~4–6″ / 100–150mm below the skimmer), drain pumps, filters and heaters, blow out pipework and fit a secure winter cover. This is usually chosen in locations where freezing and heavy snow are expected.

Step 4 — Protect plant room, pumps & filters

• Isolate and drain pumps, filters, heaters and chlorinators — use the drain plugs provided. Let the equipment dry before storing small removable parts indoors. :contentReference[oaicite:4]{index=4}
• Backwash sand/DE filters or clean cartridge filters; replace cartridges if worn.
• If you can’t remove all water from pipes, use a pool-safe antifreeze only in lines (never automotive antifreeze).

Step 5 — Fit & maintain a winter cover

Put on a winter debris or safety cover and tension it correctly — loose covers collect debris and allow water to pool. Check cover tension after the first few days and clear snow off regularly to avoid collapse or damage. Safety covers add protection against accidental access; standard winter covers do not. :contentReference[oaicite:5]{index=5}

Step 6 — Monitor through winter

Visit your pool every 2–6 weeks while it’s closed or on reduced servicing: skim debris off the cover, remove standing water from cover depressions, and check equipment and water level. If you keep the pool running, run filtration periodically (modern guidance suggests short cycles regularly rather than long continuous runs) to prevent stagnation and freezing risk.

Common winter issues & what to do

Green or cloudy water when you open the pool

Shock and treat with algaecide, clean or replace filters, and run filtration continuously until clarity returns. Test and rebalance chemicals before swimming.

Frozen equipment or cracked pipes

If freezing has damaged equipment, turn off power and call a qualified pool technician — avoid rapid heating attempts that can worsen cracks. Prevent by fully draining and blowing mains where severe frost is expected. :contentReference[oaicite:8]{index=8}

Recommended products & tools

• Multi-parameter test kit or digital tester
• Pool shock (unstabilised chlorine) and winter algaecide
• Filter cleaner / backwash equipment; replacement cartridges or media
• Quality winter or safety cover and cover pumps to remove standing water
• Air compressor or shop-vac (blow mode) for clearing pipework if winterising

Winter can be tough on hot tubs — but with a little preparation you can keep yours safe, energy-efficient and ready to use. Follow the checklist below whether you plan to use the tub through winter or put it into short-term winter care.

Quick Winter-Ready Checklist

• Test & balance water chemistry (pH, alkalinity, sanitiser)
• Shock the water and clean/replace filters
• Inspect the cover & clean it; add a cover lifter if needed
• Insulate lines and protect the cabinet
• Decide: keep heated & maintained, or winterise fully

Step 1 — Decide how you’ll use the tub this winter

There are two sensible approaches:

• Keep using it: Maintain normal water temperature, check chemistry weekly, and ensure circulation runs to prevent freezing.
• Winterise and shut down: Drain the tub, blow out water from pipes, remove filters and store them, and protect equipment from frost.

If you use the hot tub periodically during winter, keeping it running on a low but steady schedule is often safer than draining — it reduces the chance of pipes freezing and avoids re-filling and re-balancing later.

Step 2 — Water care before cold weather

1. Test and balance: Use test strips or a digital kit to check pH (7.2–7.6) and total alkalinity (80–120 ppm). Correct imbalances before temperatures drop.
2. Shock the water: Apply a spa shock to remove organics and help the sanitiser work well.
3. Sanitiser level: Ensure sanitiser (chlorine, bromine, or alternative) is in the correct range. Low sanitiser + cold = algae risk.
4. Filter clean: Remove filters, rinse thoroughly and soak if needed — replace at least annually or sooner if worn.

Step 3 — Keep circulation and heat working (if you plan to use)

Circulation prevents standing water in pipes that can freeze. Recommendations:

• Set circulation to run a minimum of 2–4 hours per day (more when temps fall below freezing).
• Set the heater to a conservative temperature (e.g. 37–39°C) if you’re using regularly; lower if you rarely use it but still want to avoid freezing.
• Use a programmable timer so the pump runs automatically during the coldest parts of the day/night.

Step 4 — Winterise fully (if you plan to shut down)

If you choose to winterise, do this carefully — mistakes can lead to frozen pipes and expensive repairs.

1. Turn off power at the RCD / isolator before draining and working on the equipment.
2. Drain the shell: Use the built-in drain or a submersible pump to empty the tub completely.
3. Blow out plumbing: Use an air compressor or a shop-vac on blow mode to push water out of jets and lines. Remove inline filters and drains where applicable.
4. Add pool-grade antifreeze (optional): If you can’t remove all water from lines, use an appropriate non-toxic antifreeze made for pools/spas following manufacturer guidance. Do not use automotive antifreeze (ethylene glycol).
5. Remove and store filters & electronics: Keep them dry indoors.
6. Cover and secure: Clean the top of the shell and cover then put the cover on and strap it down. Add extra insulation (a thermal blanket under the cover) if you expect prolonged freezing.

Step 5 — Protect the cover, cabinet & equipment

• Inspect the cover for rips, wet insulation, or sagging; repair or replace if necessary.
• Clear snow off the cover regularly — heavy, wet snow can deform it.
• Consider an insulating skirt for the cabinet or a windbreak to reduce heat loss.

Step 6 — Regular winter checks

Even if you’ve winterised or kept the tub running, visit once a week to:

• Check water level and top up if needed.
• Inspect the cover and clear snow/ice.
• Listen for unusual pump noises and check for leaks.

Common winter problems & solutions

My pipes froze — what now?

If you suspect frozen pipes, turn off power, call a qualified hot tub technician and avoid pouring hot water on pipes — rapid temperature changes can crack equipment.

There’s cloudy water after re-opening

Shock the water, clean/replace filters and run the pump continuously until clear. Test and adjust chemicals after 24–48 hours.

Cover has water logged and become heavy

Replace the cover — waterlogged foam loses insulation and invites mould. We can advise on replacement options at Hot Tubs Staffordshire.

Tools & products we recommend

• Quality multi-parameter test kit or digital tester
• Spa shock and appropriate sanitiser
• Filter cleaning solution and replacement filters
• Non-toxic pool/spa antifreeze (for lines only)
• Insulating thermal blanket and sturdy hot tub cover
