Read All Instructions Carefully Before Using.
1. Attach the Drain Cleaning Bladder to a hose connected to a cold water faucet.
2. Place into the clogged drain - a minimum of 6 inches.
3. Turn on the cold water slowly to full pressure. As water fills the Drain Cleaning Bladder, the unit will expand to fit snugly against the walls of the pipe. When the unit is fully inflated, water will be forced out the end of the Drain Cleaning Bladder to put pressure on the clog and push it through the drain pipe.
4. Turn the water off before removing the Drain Cleaning Bladder. Do not leave bladder unattended while water is running. If water backs up past the bladder, shut water off immediately. Store Drain Cleaning Bladder in dark, cool, dry place.
Bathtubs - Insert the Drain Cleaning Bladder through the overflow drain after removing the plate. Make sure the Drain Cleaning Bladder is inserted past the point where the two drains intersect.
Swimming Pools - Use the Drain Cleaning Bladder to prime and flush pool lines.
Showers - Fully insert the Drain Cleaning Bladder into the line after removing the drain plate.
Washing Machines - Insert the Drain Cleaning Bladder into the drain line at least 6" and as close to the clog as possible.
