SpaChoice 1-Pint Premium Seal A Leak, Hot Tub Leak Sealer, Made in USA

Soon after I bought a Calavera 4-person hot tub, I realized there was a minor leak. Eventually, I drew a pencil line along the water where the leakage stopped. Subsequently, I found out the tub lost a gallon of water every day.The manufacturer sent a technician to repair the leak, but he arrived too late in the evening. They then sent a second technician who said, "because there was no water in the electrical compartment, there was no leak." I disagreed. He said, "you don't have to agree. I've been doing this for 20 years." I then asked him twice, "why does the leakage stop at the line I drew? He did not answer at all.I then bought a bottle of Spa Choice, Seal a Leak. I bought this because the application was simple when compared to some other similar products. For the first time, I used it as shown on the bottle. This product worked. It's been more than 70 hours since I applied the Seal a Leak. There has been no leak at all.

Listen to me closely you dont need to read any other reviews, I have a 2007 cal spa and it had recently developed a number of small leaks, I would lose an inch of water over 2 days, I pulled the insulation out and it was a spaghetti mess of water and air lines, there's no way I was getting in to fix them all, so I went looking for options including buying a new 12,000 tub, after searching online I found this product, I followed the directions and I slowed down, then I tried a 2nd try and it almost stopped so I said screw it and put the whole bottle in, BOOM no more leaks and it's been running for 2 weeks and hasnt lost a drop , the nice thing about this one is you dont have to dump your water just rinse your filters a few times and you are good after your leaks stop. I'm going to buy a second bottle as backup they should change the name to Liquid Magic. I swear it's that good.

I have a Dimension One hot tub that was leaking water at moderate rate - about an inch in a month, but I could clearly see water drippong under it (hot tub sits on the deck).I have applied the product (slightly more than recommended, about 3 oz per 350 gallons tub) and after first application I could clearly see driping reduced. I have repeated applications 2 more times, which ended up 16 oz bottle - after third doze leakage is no longer noticeable. I've emptied a tub to get rid of leftover (just do not know how safe it is to use) and will look more carefully for the signs of leak after refiill, but so far it seems to solve the problem.Note, that after the application there is no residual on the walls of the hot tub - what's left looks more like a coarse salt sitting at the bottom of the tub, goes away easily when you drain the tub.UPDATE: after changing water in the hot tub leak is back, actually even worse than it was before the application.Bottom line: do not recommend, does not create permanent fix.

I have a 400 gallon, 17 year old hot tub. At least two Jet seals started leaking right after Fall startup (I drain and shut down hot tub during summer.). Thought I would try this instead of draining and crawling underneath. First thing, the recommended one ounce for 400 gallons seems like not enough, and it's not. I used two ounces initially. 24 hours later, no difference. I put in 3 more ounces. 24 hours later I did notice the leak slowing down. I added two more ounces. 24 hours later, the leak had stopped. I topped off the tub and added chemicals. One week later, it was slowly leaking again. I added about two more ounces, then 24 hours later, added two more ounces, and within 2 more days, the leak had stopped again. One month later, I am writing this review.Bottom line, it did work. But no way is one or two ounces going to work. I saw one person say he dumped the whole bottle (16 oz) in at once. I think slowly adding a couple ounces every 24-36 hours until it stops would work better. I used about 12 ounces over about two weeks total. Patience is key. It took a while, but easier than trying to find and reseal the leaking jet seals. That will be a summer job. Will update this review if/when it starts leaking again.

I have a LA Spa that is about 25 years old that I bought used 12 years ago. In the last two year the spa has developed several leaks from old age in the jet plumbing. I have attempted to fix the issues, but finding the leaks and cutting through the foam is just frustrating. More leaks have developed and I was losing 1/2 of the spa volume in several days of operating. As a last resort I used this product. Instead of using just the recommended dose I poured the entire bottle, all 16oz into the skimmer. After 12 hours of running the pumps there was no difference in leakage and I thought this was it. However, after 24hrs all leaks stopped. It is a true miracle. Now I am going to turn everything off and let the spa sit for 48hrs and then drain and refill. Hopefully this will last, even if it is only six months and I have to do it again I think it is well worth it compare to cuttings everything apart.

You have to keep using

Fixes your hot tub when you're too lazy to. My hot tub I got used of course. They swore they drained it. Of course they didn't. Lots of leaks... I mean alot. Used up both bottles and it can almost hold up to the jets which is insane if you ask me. The holes this stuff plugged, I thought were way too big and it was a hail mary. Well it plugged them. I just dont use the jets on one side because not to fault the product the leaks were just too big for anything to realistically seal and it did seal them. I just cant fully pressurize them or it'll weaken the seal. Honestly this worked a million times better than I thought it would. Kudos to you
