1. Let’s start by emptying the contents of the dirty water tank and the bladder.
2. Using a Phillips head screwdriver, remove the 3 screws that hold the black plate to the bottom of the Tank-In-Tank®. Then, check bladder for correct positioning.
3. If bladder is correctly installed, the screws are tightened properly, and the tank-in-tank continues to leak, you’ll need to get a new tank.

NOTE: If you’re doing a water rinse on the carpet, it’s a good idea to fill the SmartMix® bottle with warm water and set the SmartMix dial to High Traffic. It will still rinse the carpet with water and this will help to flush out the system.
