Marlig Fix-A-Leak
The Marlig Fix-A-Leak Pool and Spa Leak Sealer is a 32 oz bottle that promises to fix leaks in your swimming pool or hot tub. According to the manufacturer, the product will fix 80% of leaks. However, customer reviews have mixed results on the effectiveness of this product.
One customer, Kirby J Kraft, used the product on their hot tub and found that the leak was temporarily fixed during treatment, but re-appeared after draining the hot tub and allowing for a 7-day cure. They did follow the instructions on the Fix a Leak website (www.fixaleak.com) and believe that this product is good, but did not work for them. Ultimately, their leaking tub was fixed by a spa dealer.
Another customer, John, used the product on their Jacuzzi 480 gallon hot tub and found that it worked for about a week and a half, but the slow leak came back. They then used the remaining 2/3 of the bottle and the leak has held for about two weeks. The instructions did not guide them on how to help a hot tub leak.
On the other hand, another customer, John, had a different experience and found that the product actually worked for their 5 year old hot tub. They had been losing more water each week without any use and had noticed water pooling in two locations on the outside of the tub. They were quoted $5,000 by a hot tub company to fix the leak, but decided to try this product and it worked for them.
The instructions for use are as follows:
- Remove all cartridge filters.
- Pour the entire contents of the bottle into the filter intake or directly into the spa.
- On day 1 run the spa for 4-6 hours, alternating between the low and high-speed jets.
- Since the jets usually run on a 15-minute cycle, you must be present to restart once cycle kicks off.
- After the 4-6 hours you can shut off your spa or just allow the recirculating pump to periodically run its cycle.**
- On day two, if the leak has slowed but not stopped, broom the bottom of your hot tub/spa before restarting the process as you did on day one of alternating between high and low speed jets for 4-6 hours.
- After day two leave the spa off for 48 hours. During this time frame check to see if the water level is stable and if the hot tub/spa pad remains dry.
Pros:
- The product promises to fix 80% of leaks.
- It is a cost-effective alternative to hiring a hot tub company to fix the leak.
Cons:
- The product may not work for all types of leaks.
- The instructions may not be clear for hot tub leaks.
- The product may not provide a permanent solution for the leak.
