This stuff is a savior if done correctly and patiently
I shut down and drained my Hot Tub approximately 3 years ago. Recently I decided to reopen it and it was a mess. When I drained it apparently I did not get all the water out of the low spots and dead ends. I had to fix a 12 port manifold and gaskets on both sides of the heater. I still had about 15 leaks that I could not get to without removing just about everything. But none were parts like manifolds or cracked elbows. I poured 6 oz of this stuff right into water. I removed the filter and kept running all jets for 4 hours continuously. I let it set overnight and then drained it for 72 hours figuring the sealant would cure better. Incredible, it is bone dry underneath and did not lose any water at all. I would imagine my spa company would have been here at least 2 days and the cost would guaranteed have been at least 1500.00 easy. The spa is at least 10 years old so I feel I’m good for quite awhile as the glue they use will apparently compromise over time. 10 stars!

Didn't work. Possibly made it worse.
The media could not be loaded. I have what seems like a small leak, it was just a little puddle of water on the back side of my pool and I'd have to add more water every week or so. Since I used this product the leak is definitely worse. The water is now soaking my yard and I've had to fill up my pool a few times already. Now I don't know if that's a coincidence or not but either way this didn't work.

It worked!!
Hard to believe… this product actually stopped the leak in my spa!! Very very satisfied. It took two treatments and it’s held up for a couple of months now. What a break… I was at the end of the line with my spa. Very Happy

Appears to have worked - Level Has Stayed
September 2025 EDITIt has worked... I used to add water every other day and now only a bit every week. The dropping level may be evaporation... I am pleased, and so is my water bill (ha,ha,ha).Looks like it has worked well enough... Time will tell. At least the water level does not go down as fast, that's very positive.

It really works
I tried numerous bottles of Fix A Leak...that stuff never worked. I used this one time in my above ground pool....it works! I followed the directions exactly. Amazing stuff. Thank you to whomever invented this amazing product!!

Stopped our leak
We were losing an inch or two a week from pool it was an inflow line. We had tried other products but they did not work. One use and we have not had any further water loss

Waste of money.
Product failed to seal the leek in our hot tub. I have used Marlig's fix-a-leek many times and I am genuinely sorry to have wasted my money on this product. My 17 year old Sundance Montego has a slow small leek in the therapy seat. We have tried many time and paid allot of money to try and have it fixed, finally one company recommended Marlig's fix-a-leek, which stops the leek for about 6 months before I have to use it again. Replacing the spa isn't an option at this time because it's in a room that was built around it and we cant afford to have the wall taken down and put back up in addition to getting a new spa. Decided to try this to see if I could get more than 6 months out of it. This product did not work at all. There was no change in the amount of water lost, all it did was waste my time and my money. DO NOT BUY.
