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

This absolutely works!! Fixed a big crack with JB Weld but the Hot tub was still leaking. Removed all the insulation and found it was leaking from the middle of the footwell in many places. I put this in per the instructions and no leaks. Every week I was filling for 20 minutes and now I just top off for a minute. Amazing!

Does not work. Wouldn’t let me do no stars

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!

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

It didn't work the way it was supposed to

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.

Stopped the leak on the first try!!

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.
