Fix-A-Leak by Marlig for Swimming Pool Spa Hot Tub Leaks 32 oz,White

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!

This stuff is amazing and I highly recommend it. I have an inground swim spa that is about 35 years old. It started leaking about 3 years ago, just minimally at first and then it got progressively worse. Finally I hired a leak specialist last year who found cracks in the skimmer and 3 valves. He sealed the leaks in the skimmer with epoxy and told me where I could buy new valves which I did and replaced the old ones. Cost me $600. However the leaking continued to the point where I just gave up on trying to find a fix and hen I heard about Fix a Leak. I figured what the heck so I bought the 32 once bottle. I watched a dozen videos on You Tube and finally decided to ty it a week and a half ago. I followed the directions exactly. I drained the spa and refilled it and no leaks whatsoever . A really fantastic product.

My spot has been slowly leaking for about a year. I called a company that fix a spas, and This is what was recommended for me to buy. I followed the directions and did two applications.I was really very skeptical but it worked beautifully. My spa is no longer leaking. I should have done this a long time ago. Worth getting.

Had a pretty constant leak in hot tub piping that is inaccessible. The first treatment did not fix it completely, but definitely slowed it down to a very slow and manageable leak. I'll do a second treatment this fall prior to draining for winter. I am happy with this product.

I've used it last year and then again this year. The fix does not seemed permanent but it is doing something. I just learned the right way to apply this liquid fix. You will need some plumbing skill. Take a piece of PVC tubing and pout the appropriate size male fitting at one end to fit the skimmer port, like the winterizing plug. The tube top of the tube has to be higher than the pool pump for this to work. It was create a pressure to push the liquid through the system. Turn off the return valve, plug in this tube. Fill it with the fixit liquid and then fill it with water until it reaches the top. If there is a leak, the water level will drop, let it drop and then fill up with more water again. You may have to watch and fill for a couple of days. If the leak is stopped, the water level in the tube will remain where it was or dropped minimally. Good luck!

36 x 16 vinyl liner inground pool. We have been losing about 2 inches of water each week for years. The liner was replaced in 2024 and when opened for the 2025 season we were still experiencing that obvious loss.I applied one bottle of this product per the directions, and followed those directions through the entire process.The final directions say to let the pool sit with pump OFF for 72 hours. This is to let the product react with oxygen and set up. After the first 24 hours I marked water level...48 hours later no water loss. This step proves no leak through the liner or the fittings like steps, skimmer or light.Next step is run the pool pump (recirculation bypasses the filter) through main drain only. I ran through main drain for 2 days...no water loss through main drain suction path.Final step, run through skimmer suction path only. 2 days later zero water loss.I ran our pool robot multiple times with the pump still on recirculation (bypasses filter) to get the remnants of the product (it goes to the bottom).Switch from recirculation to filter. Backlash after a few days and all done.No idea how long this will last but I'll do it again next year with our openWould I recommend this to a friend? Yes.
