How to use Fix A Leak correctly in hot tubs and spas
When fixing a hot tub or a spa, the water temperature should be no less than 70°F or 21°C.
The 32 oz. pool size bottle can be used for hot tub and spa repair if the 8 oz. bottle cannot be acquired. By using 1/3 of the 32 oz. bottle or less, follow the same directions for a hot tub or spa leak. If water loss exceeds 1 inch in 24 hours, it may be beneficial to purchase the 32-oz bottle for multiple applications if needed.
Most repairs in hot tubs and spas will last between 1-2 years.
- Determine water loss in 24 hours. Fill the spa to the original water level.
- Immerse the bottle in hot water for 15 minutes. Shake well before use.
- Remove all the cartridge filters.
- Pour the entirety of the 8 oz bottle into the filter intake or directly into the spa.
Day One: Run the spa for 4-6 hours, alternating between the low- and high-speed jets. This step requires supervision. If the spa has only one speed, run the jets in 15-minute on/off increments for a total of 4-6 hours.
Day Two: Brush the bottom of the spa, then follow the same steps as Day One. Adding more product is not necessary at this time.
Once comfortable the leak has stopped, allow 48 hours with the spa off to confirm no further water loss.

Drain the spa after 48 hours as long as night temperatures remain above 40°F or 4°C. While emptying the tub, rinse and wipe down the sides with a warm, soft cloth to remove any residue that may be present on the spa surface. If not done properly a white residue will remain. Allow the spa to sit empty for 4-7 days. The draining process allows air to get to the inside of the plumbing, helping the product to cure and creating a longer-lasting seal.
