Fix A Leak Pool Leak Sealer - 8 oz

It worked for me. I have a 16 year old portable hot tub that I recently had to push back on to it's side to replace the drain fitting at the bottom and it sat empty on it's side for probably 8 months. I had taken all the skirts off to do that work, and when I went to refill it discovered it was now losing water. It was losing water from the hose connections, the gasket that goes in the middle of the jet, and the gasket that seals against the surface of the hot tub shell. It was not a huge amount of water but an overwhelming project to take on, so I gave this a try and super happy that I did. You can see in the before an after photos, the product forms a kind of plastic seal where the water comes out, that eventually hardens and keeps any more water from coming out. I did feel like the tub was still leaking a little at day 4, and then we had 3 days of rain, and after that there were no more leaks.

surprised but it actually worked. Leak stopped after 24 hours

I'm not sure how this stuff really works, but it worked for my situation. I had just had a spa service visit which cost me $180 for a leak and unworking pump for one of my seats. All they did was confirm I had a leak and stated the pump has stopped working (nothing I didn't already know). They suggested I buy a new hot tub since mine was 15 years old. I like my tub a lot, so didn't want to give up on it yet. Instead, I googled sealants which work underwater and was planning on draining tub and applying gunk around all my jets and light fixtures. Instead I found a YouTube video where a guy demonstrated using this stuff. I was doubtful, but decided it would be cheaper and easier then doing what I had planned. Well, I'm no longer a doubter. I tried this stuff and not only did it fix my leak, it also got my pump working again!! Not sure how long it will last, but it definitely did the trick for now.

This review is after a week and applies only to outdoor recirculating fountains. After trying a number of other unsuccessful ‘fixes’ this stuff appeared to work pretty quickly (miraculously?) but the leak returned after a couple days; gave it a second dose, again seems to have worked. For fountain application it’s ability to penetrate everywhere water goes is a far, far superior fix to using spray rubber, epoxy, aquarium sealer, etc, as 1) the problem is often deeper than a surface sealer application can reach and 2) fountain cracks open up more with the full weight of water, so fixing it ‘dry’ is no good. I’ve even used underwater sealer but you’re still limited to the surface you can reach — and cracks from freeze/thaw often occur in inaccessible areas (even on an empty fountain). For small fountains, bird baths, etc that only hold several gallons of water, the smallest 8 oz bottle for under $15 is plenty for a number of applications…and even if it periodically needs a booster shot, it’s still the best solution by far to all alternatives for any persistent leaker. Think of it, in the light least favorable, as the easiest, cheapest, quickest, least labor intensive option that may work and you should try it before anything else for leakers. Word to the wise: if you don’t exchange the water after a couple days birds and animals will avoid it while it still has the chemical aboard…but it doesn’t seem to harm ground cover when dumped on it.

It worked well for 1 week and I thought the issue was fixed. I was really happy about it. I have a small leak in my hot tub, which loses about an inch of water a week. I followed the instructions perfectly. But after a week, the leak came right back. Bummed it didn’t do what it says

My Sundance hot tub was leaking water at about 5 gallons daily. Service guy said it was a difficult fix, pipes were underneath. I took out the filter and slowly added Marlig so it would get sucked into the intake. Next day, there was no drop in water. 15 days later, water level was still unchanged, not leaking! After about 20 days, the pool level dropped about 6 inches. Refilled the tub and repeated the process. Again, it stopped the leak immediately. Filter is still out. Will see how things go, I will update my rating either way depending on what happens. Also noted that one of the jet outlets was very sluggish after use; it may have plugged it. More to come. Well, I added the second bottle and it has held now through April. I have not returned the filter to the tub, continued with routine chemicals. The tub is not crystal clear, my suspicion is that there is residual particulate from this product that may be helping to continue stopping the leak, like platelets that clot blood. (Sorry for that analogy, I am in health care!) That being said, it has not dropped any water in the past 4 months! That is a whole lot better than having to refill 20 gallons every day, or worse having to replace the tub. I plan to change the water, install a new filter and will then see how it does. My review started with 3/5 stars, now up to 4/5 stars. Bottom line, if you are in dire straits, go for it, you have nothing to lose and may buy you more time. 04/25/21- Filter is back in, so this is NOT a permanent fix. You will stop the leak as long as the sealer stays in. Disappointing, but still cheaper than a new tub at this time. Back to only 3 stars

My hot tub repairman recommended trying this for a slow leak. Somewhat to my surprise, it worked and sealed the leak!

This review was originally written on 23 Oct 2014; updated today, 20 Nov 2014. I have a 10-year old 500 gallon hot tub with 6 pumps running the heater, filtering system, and 84 jets. Inside the shell, all the parts and plumbing are buried beneath sprayed-on foam insulation - in some locations as much as 6" thick. Over the years I have replaced two of the jet pumps which had piping connectors that I had to dig-out of more than 4" of foam insulation; that arduous and messy experience taught me that there was no hope in finding the source of a leak underneath all of that foam. In May of 2014, When my tub developed such a leak, I sought an alternative to tearing the tub apart and stripping-out the foam. I watched several you-tube videos wherein other SPA owners facing similar challenges used a "Seal A Leak" product by "SPA Choice" and avoided the task of tearing down their tubs. Although skeptical, I decided to give it a try; in June, I bought the product through Amazon but it came to me from a third-party distributor; it worked at first, but then failed over time (about two weeks) - subsequent treatments with the same product gave no better results. Then, in July 2014, I found this product (Fix A Leak) on Amazon and decided to give it a try. My initial treatment in mid-August 2014 was half the bottle through the filter chase; since then, until now (20 Nov), it had been holding up well. I wrote my first review for this product on the 23 Oct after it had held-up for about 3 months. This past weekend, I noticed my tub has begun to leak again, at about the same rate that it had leaked before the first treatment. Although it's leaking again, the empirical evidence suggests this product is superior to the other because this one held-up for four months as opposed to two weeks. I retreated the tub today (20 Nov), and will again if necessary; the prohibitive high-cost of service and parts dictate it warrants a try. I will tear the tub down only after giving this product multiple chances to prove itself incapable of a permanent fix. It has worked for me, never mind it was only four months, that's better than spending $2,000.00(+) with no guarantee their repair won't leak again after only three months - at least here locally, none of the techs I spoke with will warranty their leak-repair work beyond 90 days. After several discussions with multiple technicians, I've concluded the industry's permanent solution to a leaking Hot-tub is to replace it. New, my tub cost more than $7K ten years ago; today, one like it, will cost twice that amount. At a cost of only $15 bucks for this 8oz bottle, what can you lose? Your SPA's leaking already, or you wouldn't be reading this review, and this little bottle is certainly cheaper than a service call - in this area a service call is $150.00 just for the tech to show-up and look at it. I recommend you give this product a try - if necessary, several times.
