Is the top ring of your Fast Set pool deflating?  

Inflate the air chamber and securely close the valve. Wipe around the valve with soapy water to determine whether there is an air leakage. If you discover there is an air leakage, follow these simple steps:

Step 1: Deflate the top ring by opening the valve.

Step 2: Prepare some hot water over 80ºC (176ºF) and place the valve inside the water for approximately 1 minute (we suggest wearing kitchen gloves during this part of the process to protect your hands from the heat of the water).

Step 3: Wait until the valve has cooled. Once cooled, it should have recovered to its original shape. Repeat the test to ensure the valve is no longer leaking air.
