Spa Liner Leaks (Air Loss or Punctures)

What you might notice

• Spa losing air faster than usual

• Soft or deflated walls

• Hissing sound coming from the liner

• Spa not holding pressure overnight

• Visible damage, scuffs, or puncture marks on the liner surface

Common causes of liner leaks

Understanding what causes liner leaks can help you prevent them in future. The most common causes include:

• Sharp objects: Jewellery, pet claws, or debris in or around the spa can puncture the liner.

• Valve issues: The inflation valve or drain valve can develop small leaks over time, especially if not fully tightened.

• Seam stress: Repeated inflation and deflation, or overfilling, can put stress on the liner seams.

• UV and weather exposure: Prolonged exposure to direct sunlight or freezing temperatures can degrade the liner material.

• Chemical imbalance: Incorrect water chemistry (particularly high chlorine levels) can weaken the liner over time.

Step-by-step: Finding the leak

1. Drain the spa completely.

2. Inflate the liner fully using the pump.

3. Listen carefully for any hissing sounds — move slowly around the entire spa.

4. Mix a solution of washing-up liquid and water in a spray bottle.

5. Spray the soapy water generously over all seams, valves, and surfaces.

6. Look for bubbles forming — this marks the location of the leak.

7. Mark the spot with a pen or piece of tape so you don't lose it.

Tip: Check the inflation valve and drain valve first — these are the most common leak points and are easy to overlook.

How to fix

Check your warranty first. If your liner is still under warranty, please don't patch it yourself — send us photos so we can assess it.

• Under warranty: within 12 months of receipt for spas with an integrated heater, or 6 months for spas with an external heater (see our warranty page)

  • Take clear photos or a short video showing the leak location and the bubbles forming.

  • Please use the chat widget at the bottom of the page to contact our support team — we'll assess whether a replacement liner is needed.

• Out of warranty: use the repair patches supplied with your spa

  • Make sure the area to be repaired is completely clean and dry.

  • Cut the patch to a size slightly larger than the hole or tear.

  • Apply a strong adhesive to the repair patch, then cover the damaged area.

  • Smooth the surface to remove any air bubbles.

  • Leave to dry for 12 hours before using your spa.

  • Replacement patch kits are also available to purchase if you need additional patches.

Fixing a leaking valve

If the leak is coming from the inflation or drain valve rather than the liner itself, try the following:

• Ensure the valve cap is fully tightened and seated correctly.

• Check that the valve seal or O-ring is not damaged or missing.

• If the valve is damaged, contact us via the chat widget at the bottom of the page — we may be able to supply a replacement valve.

Preventing future leaks

• Ask bathers to remove sharp jewellery before entering the spa.

• Keep pets away from the spa to avoid claw punctures.

• Avoid overfilling — inflate only to the recommended pressure level.

• Store the spa indoors or use a cover when not in use to protect from UV and frost.

• Maintain correct water chemistry to avoid chemical degradation of the liner.

• Inspect the liner regularly for early signs of wear, especially around seams and valves.
