The RIDGID PowerClear R7 is designed to help users clear common sink, shower, and tub clogs without needing professional tools or experience. Its compact size and built-in AUTOFEED system make it easier to control the cable and work through blockages safely. This guide focuses on how to actually use the machine, from setup to completion.
Step 1: Understanding the Machine
The machine comes with a cable inside the drum, hose for inserting the cable a foot pedal and power cord.
Switch Settings
The switch has 3 settings
- I : which turns on the machine when you step the foot pedal
- 0 : Machine is OFF
- II : For a quick jerk in the reverse direction in case the machine hooks onto a piece of wood or something it cannot get out of
Note: II is not reverse mode.
Autofeed
You can choose to use the autofeed lever for the machine but it is also fine to pull the cable out manually.
Safety
Always use safety glasses and gloves to prevent injury.
Step 2: Position the Machine
Begin by placing the PowerClear R7 on a stable surface close to the drain opening. Position it so you can comfortably reach the foot switch and the forward-off-reverse control without overreaching.
If you are using the Autofeed, Hold the AUTOFEED guide hose so the end remains within about fifteen centimetres, or six inches, of the drain opening. Keeping the guide hose close to the drain helps support the cable and prevents it from twisting or whipping.
Before turning the machine on, manually insert the cable into the drain. Push at least 15cm of cable into the pipe by hand. This ensures the cable is properly supported inside the drain before it begins rotating and reduces the risk of sudden movement when the motor starts.
Step 3: Turn on the Machine
Set the direction switch to forward (I).
Step on the foot switch to start the machine. The cable should rotate smoothly and steadily. If it feels unstable or uneven, release the foot switch and check the cable position before continuing.
Step 4: Cleaning the Choke
Move slowly and allow the machine to do the work rather than forcing the cable forward. As the cable travels deeper, resistance usually indicates a bend, a trap, or the blockage itself.
When you reach a blockage, stop advancing as soon as the cable stops turning freely. Pull the cable back slightly using the retrieve function until it spins smoothly again, then advance it forward slowly. Use a controlled in-and-out motion and allow the rotating tip time to break up the obstruction. Forcing the cable rarely helps and can damage both the cable and the pipe. Continue this process until the cable moves forward easily and water begins to drain.
If the cable has difficulty passing through a trap or tight bend, short downward movements can help guide it through. In some cases, briefly switching to reverse while applying light forward pressure can help the cable get started. Reverse should only be used momentarily and only to assist movement, as extended use can shorten the life of the cable. Switch back to forward as soon as progress is made.
Step 5: Removing the Cable
Once the clog is cleared pull the cable back into the drum. Maintain a firm grip on the guide hose as the cable returns. Turn the machine off and unplug it after the drum has fully stopped. At this point, the drain should be flowing normally. Running hot water for a few minutes can help flush out any remaining debris and confirm that the blockage has been fully cleared.
