Hold the main shaft of the auger steady with one hand. With the other hand, simultaneously push the handle down towards the shaft and turn it in a clockwise direction. This action extends the metal snake out of the protective tube and into the toilet's trap and drainpipe. The rotating motion helps the auger head to either break through the blockage or to hook onto it. Continue this motion until the entire length of the cable is extended or you feel the clog give way. You may need to pull back slightly and push forward again to work through the clog.

Goal: Clear the clog

  • If you feel resistance, don't force it too hard. Gently work the auger back and forth while rotating to navigate bends or break up the clog.
  • A sign that the clog is clearing is when the water level in the bowl begins to drop.

FAQs

What are the most common signs that my plumbing vent stack is clogged, and not just a regular drain?

Common signs include multiple slow drains throughout your home, gurgling sounds from various drains or toilets, or a persistent sewer gas odor. If these symptoms appear in several fixtures simultaneously, it's a strong indicator of a main vent stack blockage rather than a localized drain issue.

How do I safely access my roof to clear the vent stack, especially if I'm not comfortable with heights?

Always use a sturdy extension ladder, like the XTEND+CLIMB 760P+, ensuring it's on level ground and secured. Wear slip-resistant shoes (e.g., Shoes For Crews) and consider having a spotter to stabilize the ladder. If you're genuinely uncomfortable or inexperienced with roof work, it's safer to call a professional.

What if my garden hose isn't long enough or powerful enough to clear the blockage in the vent stack?

If a standard hose like the GardenJoy 5/8 in. x 50 ft. doesn't reach or clear the clog, consider using a longer, more flexible hose like the Pocket Hose Silver Bullet 100 ft., which is designed to be kink-free. You might also need to use the drain auger (THEWORKS 3/8 in. x 25 ft.) as the next step for more stubborn blockages.

What should I do if the drain auger gets stuck in the vent pipe during the clearing process?

If the auger gets stuck, try gently rotating it counter-clockwise while pulling back to disengage it from the blockage or a pipe joint. Avoid excessive force, as this could damage the pipe or the auger itself. If it remains firmly stuck, do not force it; you may need to call a professional.

What you're going to do now is kind of grip it here, and you're going to press down on the metal on the handle here. Ideally, it's going to go down up, and then down again, and then push whatever's clogged in here, down through the o-ring and into the larger outlet hole at the base of the floor. Now, what I'm doing is I'm turning this handle clockwise, as I'm pressing it further down, and you may have to move this shaft up and down a little bit to get it going. So what I'm doing here is I'm putting it more straight up and down, and I'm holding the black portion here as I turn the handle clockwise, as I push down. And what may happen is you may notice water start to go down as you're moving this forward, and that's a good sign.
