The Real Deal!
I followed directions to the T and...@#%*! THIS STUFF WORKS!! As a repair tech I'm well familiar with "stop leak" products used in many industries. Some work better than others and exact circumstances can make all hit or miss. I was actually pretty skeptical about the ability of a working solution (punintended) to fix my good ol' 4-person hot tub, the victim of a winter power failure that caused freezing in the water lines. That would be a fatal condition for most tubs, but NOT the hard-won "portable" tub that I vowed I would never try moving again in my lifetime. Not that there's all that much of that remaining, but all the more motivation to bring my beloved "Think Tub" back to life. So, after rebuilding the heater (too old and costly to replace) and replacing the pump, it was with INDESCRIBABLE sadness I discovered the tub was leaking water from points unknown at rate that would make it more suited as a planter. My indefatigable nature--exacerbated by $200 repairs already expended--led me to Fix-a-Leak. Reviews were surprisingly positive, but even if it wasn't snake oil I didn't have much confidence it would work for my potentially sieve-like tub. After some reflection I decided I could spring for another $22 before crying "uncle!" May well have turned out to be the best $22 I've ever spent! It took me 3 months to garner enough courage and emotional fortitude (oh, and time) to carry out the steps required to check the stuff out. Had I opened the bottle immediately I may have been encouraged enough to try sooner, when the weather was more conducive to the company's online "warm weather" instructions. No matter, they provide instructions for freezing weather as well and those are the ones I followed. Admittedly between those instructions and the actual liquid characteristics I was encouraged. It made sense. The solution is viscous enough, and obviously contains particulates, probably rubberized, that, when well-suspended in the tub water, could coagulate at the leak points and, eventually, HOPEFULLY build up to the point of flow stoppage. In my case, THOSE LITTLE BUGGERS DID JUST THAT! After a single treatment using the 1/3 bottle recommended for a hot tub, the leakage appeared to be completely stopped. The manufacturer mentions that without the drying-out period that is infeasible during cold weather I may need to re-apply come Spring. No worries. There are still 2 applications left in my bottle. Maybe I'll be motivated to update this review down the line. For now I have no compunction about giving this product my unreserved recommendation for pools and hot tubs. I'm a believer!

Saved my 25 year old hot tub
This was my desperate last chance to fix a leak that had started in my 25 year old hot tub. I was skeptical about this product solving my problem but figured it was worth the gamble to save the tub. Well, it worked great and hasn't leaked again for over a month now.

So far so good
Follow the directions. After the 2 day application all looked good. Per instructions I marked the water level and checked level for the next 2 days. For me no leaks in that 2 day wait.👍 Thank goodness. I have now drained the tub. After draining the tub I did use a shop vac on all the lower jets to remove standing water in the pipes. Per instructions a 4 or 5 day wait is necessary for the Fixaleak to set-up and cure. Because I used a shop vac I am hoping air will get to the leak to help the curing process. On the second day of the curing process. So far so good. The leak i am attempting to fix is at the very bottom and in the middle of the tub. Impossible for me to get to. A technician told me for the every day low price of 1400.00 dollars he could jack my tub off the ground and repair the leak. Lol. I don't think so. Come on Fixaleak. Will let folks know how it goes after I fill it back up.🤞

It works GREAT!!!
Worked the first time I used it. I would put water in my hot tub and within 6 hours the entire hot tub would have leaked out and into the yard making a swamp. Upon filling up the hot tub there was a small pool of water next to the hot tub... and then I put the "fix-a-leak" in the water as it continued to fill and the small pool of water dried up and the leak stopped!!! Amazing product.

High quality repair liquid - highly recommend
We have a 5 year old hot tub. It periodically gets a leak and water build up around the perimeter. I followed the instructions and it worked exactly as described. It’s a great value and the instructions were easy to follow.

Tried twice. Didn’t work. Worth a try but can’t recommend.

Chemistry is amazing. Fixed my annoying hot tub leak.
This stuff is amazing. I have no idea how it works but thank heaven for chemistry and smart people who know things. My hot tub was leaking so I took the side panel off, dug out a bunch of insulation and saw a jet was leaking. No big deal ... ordered a new jet put it in. Boom. I filled the spa back up and still had a leak. I pulled out more insulation and found another leaking jet and replaced that one too. Filled the spa back up and ..... you guessed it .... still a small leak. Not much water but enough to annoy me. I was tired of replacing jets at this point so I used Fix a Leak --- and BOOM NO LEAK!!!! I used two applications just to be sure and everything is great at this point. I reached out to their cusomter service with a question and got a phone call back the next day! Great customer service. One note: The instructions on the bottle are for a pool. If you are using this on a hot tub go to their website for more specific instructions there.
