Is Your Hot Tub Ready for Summer? A Pre-Season Checklist

As the weather gets warmer and evenings become lighter, many hot tub owners start using their spa more often. Whether you are planning garden parties, relaxing weekends, family time or regular evening dips, summer is one of the busiest times of year for hot tubs.

Before you lift the cover and jump straight in, it is worth making sure your spa is clean, safe and working as it should. A hot tub that has been used less over winter or spring may need a little attention before peak season. Filters can become clogged, water can become harder to balance, covers can deteriorate, and small faults can quickly become bigger problems once the spa is being used more regularly.

To help you get ready, we have put together a simple pre-summer hot tub checklist.

1. Check the Condition of Your Water

Your hot tub water should be clear, clean and balanced before regular use. If the water looks cloudy, smells unusual, feels foamy or is difficult to balance, it may be time for a fresh start.

Before summer use increases, check:

• Sanitiser levels
• pH balance
• Alkalinity
• Water clarity
• Any signs of foam, scale or discolouration

Warmer weather, sun cream, body oils and more frequent use can all put extra pressure on your water quality. Starting the season with properly balanced water makes ongoing care much easier.

If your water is already difficult to manage, a professional drain down and clean may be the best option.

2. Clean or Replace Your Filters

Your hot tub filters play a key role in keeping your water clean. Over time, they collect oils, dirt, debris and residue from chemicals and bathers. If they are not cleaned properly, your spa has to work harder and your water quality can quickly decline.

Before summer, remove your filters and check their condition.

Look out for:

• Discolouration
• Cracked or damaged pleats
• A greasy feel
• Poor water flow
• Filters that no longer clean properly

Filters should be rinsed regularly and deep cleaned as part of your maintenance routine. If they are worn, damaged or overused, replacing them can make a noticeable difference to your hot tub’s performance.

3. Inspect Your Cover

Your hot tub cover does more than simply keep leaves and debris out. It helps retain heat, protects the water and supports energy efficiency.

Before summer use, check your cover for:

• Splits or cracks
• Waterlogging
• Sagging
• Broken straps or clips
• Damage around the hinge
• A poor seal around the edge of the spa

A damaged or waterlogged cover can allow heat to escape, making your hot tub more expensive to run. It can also let rainwater, dirt and debris enter the spa.

If your cover feels unusually heavy or no longer fits properly, it may be time to replace it.

4. Check for Leaks or Water Loss

A small amount of water loss can happen naturally through evaporation and regular use; however, if you are topping up your spa more often than usual, there may be a leak. Before summer, take a moment to check around the spa and inside the cabinet if accessible.

Look for:

• Damp patches around the base
• Water pooling near the equipment area
• Drips around pipework or unions
• A sudden drop in water level
• Signs of damp inside the cabinet

Leaks are often easier to repair when they are found early. Ignoring water loss can lead to further damage, especially if components inside the cabinet become affected. If you are unsure where the leak is coming from, it is best to book a professional inspection.

5. Listen to Your Pumps and Jets

When your hot tub is running, listen carefully to how it sounds. Pumps and jets should run smoothly, without unusual grinding, humming, rattling or surging noises.

Check whether:

• All jets are working correctly
• Water pressure feels normal
• The pump sounds healthy
• Air controls and diverters are working
• There are no unusual vibrations or noises

If the jets feel weak or the pump sounds different from normal, this could point to a flow issue, blocked filter, airlock, pump fault or another developing problem. Catching these issues before summer can help prevent breakdowns when you want to use your spa most.

6. Test the Heating

Your hot tub should heat efficiently and maintain its set temperature. If it is taking much longer than usual to heat up, struggling to hold temperature, or not heating at all, there may be an issue with the heater, sensors, circulation system, cover or settings.

Before peak use, check:

• The spa reaches the set temperature
• The temperature remains stable
• There are no error messages
• The cover is sealing properly
• The filters are clean and allowing good flow

A hot tub that is slow to heat can be frustrating, especially if you are planning to use it regularly. It can also be a sign that the system is working harder than it should.

7. Check Your Chemicals and Accessories

Before summer, it is worth checking that you have everything you need for regular water care.

Make sure you have:

• Sanitiser
• pH increaser and reducer
• Alkalinity products
• Test strips or testing kit
• Filter cleaner
• Foam reducer if needed
• Spa shock
• A clean filter or spare filter

It is also a good time to check whether your steps, cover lifter, pillows, headrests, drinks holders and other accessories are still in good condition. Small upgrades or replacements can make your hot tub feel much fresher for the new season.

8. Give the Cabinet and Shell Some Attention

Your hot tub shell and cabinet can collect dirt, residue, dust and weather-related marks over time. Before summer, wipe down the visible surfaces and check for any signs of wear.

Pay attention to:

• Cabinet panels
• Shell surface
• Jets and controls
• Headrests
• Waterline marks
• Steps and surrounding area

Avoid using harsh household cleaning products inside the spa, as these can affect the water, and only use suitable hot tub cleaning products where needed. A clean spa is not only nicer to use, but it also helps you spot any small issues more easily.

9. Think About Energy Efficiency

Summer is a good time to check whether your hot tub is running as efficiently as possible. Even in warmer weather, an inefficient spa can still cost more than it needs to.

Energy efficiency can be affected by:

• A damaged or waterlogged cover
• Poor insulation
• Dirty filters
• Incorrect settings
• Heating issues
• Older components
• Lack of regular servicing

If you are concerned about running costs, we can advise on practical ways to improve efficiency, including servicing, cover replacements, settings advice and heat pump options where suitable.

10. Book a Professional Service Before Peak Season

While regular water care and cleaning can be managed at home, a professional service gives your hot tub a more detailed check before heavier use.

A professional hot tub service can help identify:

• Early signs of wear
• Pump or heater issues
• Electrical concerns
• Leaks
• Flow problems
• Damaged components
• General performance issues

Booking a service before summer can help reduce the risk of unexpected breakdowns and gives you peace of mind that your spa is ready to enjoy.

If you use your hot tub regularly, have an older spa, or simply want less to manage yourself, a maintenance contract may also be worth considering. Spafix maintenance plans are designed to help keep your hot tub in good condition throughout the year, with support available when you need it.
