Hoover SteamVac and Vax Hot Water Tanks that Crack and Leak I Really “Mist” Having A Leak-free Hot Water Tank

The problem:

My Hoover SteamVac Dual V carpet cleaner tank has leaked since the day I brought it home. The Vax Dual V and All Terrain also seem to share this problem. I’d just chalk it up to a bad machine, but other than the constant leaking, it does a great job on my carpets. It was leaking from the water valves, but then the water tank/reservoir started to crack all over the bottom and that’s when the SERIOUS leaking began. 

It seems that all Hoover machines of similar design have the same issue and I have heard of people going through 4 or 5 tanks, all of them cracking. Replacement tanks cost $90 and up, and the replacements are reported to be just as bad as the originals. That’s about half the cost of a new machine!

Silicone sealant and epoxy were not successful in repairing the tank that was not just cracking, but actually falling apart

Using silicone sealant helped temporarily. Epoxy worked for a while. Finally, enough water had leaked into the cleaner that the built-in scrubbing brushes would no longer spin

I couldn’t see sending an otherwise decent machine to the landfill and I sure as hell wasn’t going to buy a new Hoover steam cleaner! I was going to try one last fix before writing this whole thing off, and it worked! See how in the step-by-step video above.

The solution:

Even though the commercials are over the top, Flex Seal Liquid Rubber seemed like it might work. So, in combination with packing tape, cotton balls and nitrile gloves, I set out to try an experiment, figuring I had nothing to lose if it didn’t work out.

Well, it did work out and has continued to be leak-less with repeated use, and the best part is I have clean carpets! See how it was fixed in the step-by-step video above.
