Hot Tub Leak Sealer to Fix Leaks Easily - Spa Leak Sealer 16oz, Advanced Spa Repair Chemical Made in the USA - AquaDoc

It actually worked. It took much much longer to fully seal the leak then the instructions noted but it did work. I originally followed the instructions on the bottle exactly as they were written. That didn't work. Then I followed the YouTube reviews which were " dump the whole bottle in near the leak, turn off the heat but let the plum run for 8 hours and then shut the pump off for 8 hours" now I can't tell you exactly what part of this worked but it slowed the leak dramatically and I was content with that. The leak was from a faulty gasket inside the pump motor. I figured if I had to top it off every couple weeks that's good enough to get through winter. But to my surprise today I went out there to check on it and everything was dry. I did drain the hot tub completely refill it with fresh water three days ago, put the filter back in and just hoped for the best. So far... It worker

Have a 600 gallon fiberglass hot tub. Leak was most likely in one or both return lines to the pump. Made several attempts to fix the leak with negative results. Leak was not changed. was hoping for it to work but no such luck. Cant say it is a waste of money for everyone as it apparently has worked for some. Not for me so i wasted my money

Pull the filters, dump in the entire bottle and let it go 24 hours. Was losing 10+ gallons a day and it's completely stopped the leak and haven't lost a drop since. Is it a permanent solution? Probably not...but time will tell that tale (will update in due time) Update: Just shy of 3 weeks since treatment I have developed a small leak again. Treated with a second bottle and will continue to update the results. Also to note, you'll probably want to be sure to have a replacement set of filters on hand as shortly after reinstalling them they were plugged up. I will wait 48 hours this time before putting them back in.

Worked great the first time using but now I need the whole bottle.

This didn’t work for my leak which was under the tub, but I could see it helping for seal leaks around jets/lights.

Have a slow leak and tried 5 treatments per instructions then tried 3 more treatments with 3 times the quantity the directions said. The leak is about 2 gallons every 24hrs and this didn’t slow it down at all. I wrote a truthful review on this product and the company reached out to me and gave me refund on the product, i didn’t not request one. They did so on their own merit. So far that I’m changing my 2 star review to a 5 star because it may not of worked to fix my leak, but if you have a money back of the product doesn’t work on a slow leak then you have nothing to loose. Makes it worth the risk and I’m tempted to purchase another bottle and try it again.

This product was recommended by my spa technician after I discovered a small leak. He advised that using a higher quantity would yield better results. I applied four bottles for a 700-gallon spa, and it resolved the issue extremely well.

Don't waste your money did several applications not only did the leak not stop if anything it's more consistent not saying that that's the product's fault but that's just the way it is it did nothing update to this review the company reached out to me and offered me a refund for the full amount of the purchase so their customer service seems to be wonderful so although it didn't work for me I say why not give it a try if it doesn't work for you from what I seen they'll give you your money back no harm no foul

It actually does what it says it does, I had a leak that I just couldn’t find in my hot tub so I said I’ll try this thing, I had to do it twice but actually did the job effortlessly, I only used 1.5 ounces each time and I have a 5 person hot tub so I have loads left. But definitely something to have on hand if ever needed.

Advised to use by a Hot Tub Electrician. No Result after 3 Doses, so basically did not solve the Leak.

Rubbish.. never worked and followed instructions
