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

Okay, it's been over a year and I have to re-treat when I flush and change the water in my tub, but have had no leaks between changes. Very happy with this product! Update: this quick fix lasted for 4 months which I am tickled with. Then I noticed the leak begin to show once more but it was time to drain and refill the hot tub so I used to flushing agent clean the tub refilled and treated twice more with this product and the leak has stopped again. As stated in my first review if I have to do this every 3 or more months it is still much better than tearing the tub apart to find it. I still highly recommend this product. (First post):We bought a used Hot tub last year for our weekend cabin but couldn't set it up until we did our new addition this spring. I winterized the tub and worried all winter if I had done it right. Once the work was done and we filled the tub, it worked great for a couple days then I noticed a very small leak on the concrete pad where we set the tub. I was sick to think what I would have to do to fix it. After some research I discovered this product and figured what do I have to loose? I followed the instructions to the letter and it took two treatments, but after being gone for over a week, the concrete pad is dry as a bone. I'm very pleased with the outcome, and even if I have to do this every few months or even every few weeks, it is much, much cheaper than tearing the tub apart to fix this small of a leak. Fingers crossed that it will hold. I will update if need be. Would highly recommend this product.

I used 16 oz bottle in a small hot tub. Did not seal the leak. Awaiting refund from the company. Their customer service is prompt and accomodating. According to the reviews of other folks, it works for some.

My brand new hot tub (bullfrog series A) less than a year old started leaking a lot of water, I had a tech come out several times working on it they took all my insulation out and ended up using a product like this to fix it in the end. I had to re spray the bottom with spray foam almost $500 in professional foaming later and about 3 months later when draining and refilling it’s leaking water again so I purchased this and I was surprised by the instructions saying 1oz to put in for my size tub I did probably 1/4 bottom and it was not leaking as bad so I put another 1/4 in and it was almost gone so I put the rest of the bottle in and it’s been over a week and multiple uses and it’s not leaking anymore. I did read on Reddit that after you drain the hot tub and refill that you would need to reapply products like this. I have not drained mine since putting this specific product but well worth the price to stop a leak if it’s the case. Wish I would have know about this product before they ripped my hot tub apart.

The directions seemed a little quirky, but I went ahead and did what they said and the slow leak in my hot tub seems to be fixed. No complaints.

It did not stop the leak in my hot tub, but it did slow it down.

This worked great. Definatly worth the money. I was losing about 6" of water per day in my hot tub. I followed the directions and removed the hot tub filter. I added one entire bottole to my 400 gallon Hot Tub and continued to top uf water until the leak stopped. It took about 24 hours to notice the water leak slowing down. This is an excellent temperary fix because I did not want to drain the water in the middle of winter to make a repair. This product does make the water cloudy and a little slimy but it is safe to get in the hot tub. I think the material is inert polimers. This worked much quicker than I though and going on three weeks still seems to be holding up with some duribility. I would recommend having a extra tub filter handy when you reinstall. This product does clog hot tub filters but it cleans out ease...do not clean inside your house as it will clog your plumbing!

Did not work. Not worth the buy.

Used it 3 times over a 3 month period. Never sealed the leak. Used a cheaper product, it sealed after the first us.
