Our main product for Hot Tub and Spa Leaks.

Fix A Leak is a blended-concentrated material designed to seal minor leaks in the plumbing. One 8 oz. bottle is effective for hot tubs and spas ranging from 250-1000 gallons (950-3785 liters).

When fixing a hot tub or spa the water temperature should be no less than 70°F or 21°C.

Hot tub and spa leaks can be detected by notable water loss not caused by evaporation, a wet spot on the ground, or possibly a slow drip coming out of the foam insulation. If the foam insulation surrounding the tub or spa is saturated with water the hot tub or spa has been leaking for a prolonged period of time.

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 a 24-hour period 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.

Hot Tub and Spa Leaks

1. Determine water loss in a 24-hour period. Fill spa to the original water level.

2. Immerse bottle in hot water for 15 minutes. Shake well before use.

3. Remove all the cartridge filters.

4. Pour the entirety of the 8 oz bottle into the filter intake or directly into the spa.

5. 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.

6. Day Two: Brush the bottom of the spa before following the same steps as Day One.

7. Once comfortable the leak has stopped 48 hours with the spa off is required to confirm no further water loss or dripping.

8. Drain the spa after 48 hours as long as night temperatures remain above 40°F or 4°C. 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.

9. Reinstall filters, refill spa and resume normal operation. 

Cold weather precautions

Do not use more than 16 oz of Fix A Leak if the outdoor temperature is near or below freezing. The draining method is not suitable for this scenario and the remainder of the product will have to be filtered out. Follow the instructions above, but instead of draining reinstall the filters and run all of the jets for 2-4 hours. Remove the filters and clean thoroughly with warm water while still wet to remove the product. The cleaning process can be repeated if necessary. The filters can then be reinstalled and normal operation resumed. This application should get the spa through the winter season. Another application may be required once the outdoor temperatures are above freezing.
