MAV AquaDoc ADLS16 Spa & Hot Tub Leak Sealer, Liquid, Fixes Leaks in Spas & Hot Tubs, Prevents Corrosion, Extends Spa Life

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.

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.

I followed the instructions carefully, but the leak didn't stop. I ended up using the entire bottle, which seemed to fix the issue at first. Unfortunately, the jacuzzi started leaking again after just 10 days. Very disappointing product—it’s only a temporary fix.

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

I actually received prompt informative response which gave me confidence in using the product. Following the instructions and the additional guidance provided I achieved an excellent result. I was repairing a 20 year old unusable hot tub which i replaced an underwater gasket and repaired a leaking pump fitting on. It still had significant leakage and was not usable. I used this product and following the instructions exactly and additional guidance requested i have reduced the leak to very minimal loss of water and it is now fully usable. In my opinion great product and outstanding customer service. Works so well I even treated it to a coat of paint.
