Marlig Fix-A-Leak Pool and Spa Leak Sealer - 8 oz

My Hot Springs spa is 30 years old and I have performed several repairs over the last 7 years that I have owned it. It still works fine and it meets my therapeutic needs. I recently moved 700 miles and loaded it on a trailer. At my new place I set it up it and it had developed a small very slow leak. I tried finding the leak but it was obviously coming from inside the styrofoam insulation. No way could I find it. While searching for a new hot tub and being shocked by the cost of a new one, I came across Marlig Fix A Leak. At first I thought, no way could this work. But the reviews made me want to take a chance Once I received the bottle I followed the instructions removing the filters and poured in the bottle. By the very next day there was no more leak. The instructions say to drain the spa and let it sit for a few days to cure if the air temperature is not going to be too cold. Well it is very cold, below freezing at night here, so I opted to not drain the tank. I did replace the water (330 gallons). It has now been 25 days since I used the Fix A Leak and the patio is still completely dry. I am truly amazed and very happy! This stuff actually works!!! Update: one week after the above review and singing, its praises, the leak returned. I’m going to order another bottle and try it again. Update. So I ordered another bottle. This time I waited for Spring and warmer weather. I followed the directions once again and let the hot tub run on high all day. Then i I drained the tub and let it sit empty for an entire week in the warmer weather. I refilled the hot tub and no more leak. That has been six month that I did the second treatment. I think the key was to let it sit empty for a few days. I use t hot tub almost daily and in six months not a drop leaked out. This stuff really works but do empty the spa after treatment and let it sit for a few days. I am very happy that my now 31 year old hot tub still works great and doesn’t leak! I upgraded my review to five stars!!!

I had a leak coming from the hardest fitting to get to - the drain in the bottom well of the spa. I removed the front and side panel to find the leak and my friend saw it under the middle of the tub, right where the drain elbow is. We added one full bottle since my spa is 450 gallons and I ran the main 2 pumps for 20 minutes, 6 times per day for 3 days. I only have a very small drip now that as far as i am concerned is acceptable. There is no way to really get to this fitting other than draining the spa and then tilting the whole thing up to access the drain. Follow the instructions exactly. I also agitated the water in the tub with a broom to stir up the material as it is heavier than water. I did this stirring every time I ran the 2 main pumps. I did have to do this for almost three days to get it to the point of the one drip per hour that I have. I also left a small pie pan under the elbow to capture and evaporate any water. We did contact the company and they suggested that we drain the spa and do another application. We had a thought that the leak could be in one of three spots: flange to tub, cracked elbow or leak from the tube that is glued to the elbow. I applied a marine-grade silicon caulk to the drain flange/spa surface to try to minimize any further leaks. We added some die penetrant and could not tell where the leak was but did confirm that it was the drain. We emptied the drain line and added 1 oz of stop leak material to a gallon of water and poured this right into the drain line. We then filled the tub again and the company CS team member said to get a piece of tubing and apply the rest of the bottle right over the drain and then let it sit for two days before turning on the pumps. Guess what, no leaks! Amazing. I have checked several times over the last two days after the second application and no leaks. I turned the heater and pumps on to filter any residue left in the tub and we should be good to go once the chemicals are added. Overall, this product is amazing and if my friend had not told me to try this I would have had to lift the spa and replace the fitting. I would try this on any spa leaf first and see what happens. GREAT PRODUCT!

Worked perfectly but only lasted a year but what can you expect for a seal in a bottle

Used product per instruction and it didn’t fix the seam leak.

Amazing product. All leaks are fixed!

Helped but didn’t completely fix the leak

This is the 2nd bottle I bought and treated my hot tub. The first bottle didn’t work. The leak returned. Losing about 2” of water a week. This time I followed the directions exactly. (However, it says to run the jets for 20-30 minutes every hour for 4-6 hours or until leak stops. But we don’t know where the leak was coming from so we didn’t know if the leak had stopped…) Set the temp to *85. Removed the filter and poured directly into the filter area. Ran jets as directed for a day. Then let sit and cure for 48 hours. It’s been 2 weeks and I believe the leak has mostly stopped. Have had very minimal loss of water in 2 weeks! I would certainly buy this again as it’s cheaper than the alternative!

This sealer worked well in my old fiber glass Coleman tub.
