How to Find a Hot Tub Puncture – Step-by-Step Guide
If your inflatable hot tub is slowly losing air, this guide explains how to locate small punctures, slow leaks and hidden air holes quickly and safely — before the problem gets worse.
Whether you own a Lay-Z-Spa, Intex, Bestway, MSpa or similar inflatable spa, these proven methods will help you track down the leak.
Why Inflatable Hot Tubs Lose Air
Before assuming you have a puncture, check:
Has the temperature dropped? (Cold air contracts.)
Has the tub been over-inflated in warm weather?
Has it been moved recently?
Has it been rubbing against brick, decking or fencing?
If your spa deflates within 12–24 hours, you likely have a small puncture or slow air leak.
Step 1: Visually Inspect High-Risk Areas
Start with a full visual inspection.
Look closely at:
Around the base where it sits on the ground
Seams and joins
Around pump connection points
Underneath the liner
Areas touching walls or rough surfaces
The top ring (especially if pets jump on it)
You’re looking for:
Small scratches
Tiny splits
Changes in shape
Stretch marks in the material
Many punctures are smaller than you think.
Step 2: Listen for Escaping Air
Inflate your hot tub fully.
Then:
Move it to a quiet area.
Stand it gently on its side if safe to do so.
Position yourself near seams and corners.
Listen carefully for a faint hissing sound.
If your tub loses air slowly over 24+ hours, the puncture will likely be very small — but in a quiet space, you may hear it.
Step 3: Use the Soapy Water Method (Most Effective)
This is the most reliable method for finding small air leaks.
You will need:
A bucket of warm water
Washing-up liquid
A sponge or spray bottle
Mix the solution and slowly apply it over sections of the inflated liner.
Watch carefully for bubbles forming.
Bubbles = escaping air.
Move methodically around the tub so you don’t miss any areas.
This method works especially well on:
Seams
Valve areas
Bottom edges
Step 4: The “Wet Hand” Sensory Method
Common Leak Locations
From years of experience repairing inflatable hot tubs, common puncture areas include:
Base corners
Around the heater connection ports
Areas rubbing against brick walls
Underneath, where stones may be trapped
Pet claw marks on the top rings
What If You Still Can’t Find the Leak?
If you’ve tried all methods and your spa still deflates:
The leak may be underneath.
It may be hidden within a seam.
It could be multiple small punctures.
