Slowly turn on the water at the faucet. You will hear the water filling the hose and the bladder will begin to inflate, creating a seal against the inside of the drain pipe. Once sealed, a powerful jet of water will shoot out of the tip of the bladder, forcing the clog down the drain. You will likely hear a 'whoosh' or change in sound once the clog is cleared. Turn the water off immediately after the clog is cleared.
Goal: Clear the clog with water pressure
- Be prepared for some water to potentially splash back. Stand clear and operate the faucet carefully.

FAQs
What are the most critical safety precautions I need to take before getting on my roof to clear the vent stack?
Prioritize a stable ladder placement on level ground and always use non-slip footwear, like the Shoes For Crews listed, to prevent falls. Avoid working on wet, icy, or extremely windy days, and consider having a helper spot your ladder and assist. Wear heavy-duty work gloves to protect your hands from debris and potential sharp edges.
How can I be sure I've identified the correct plumbing vent stack on my roof?
Plumbing vent stacks are typically 1.5 to 4 inches in diameter and usually located directly above bathrooms, kitchens, or laundry rooms. If unsure, have someone run water in a sink or flush a toilet while you listen near the vent pipe on the roof for gurgling or suction sounds that indicate it's connected to that fixture. You can also trace visible pipes in the attic if accessible.
Do I really need a specialized drain auger, or can I clear the clog with just a garden hose?
A garden hose with a high-pressure nozzle is often effective for clearing minor clogs like leaves or small nests. However, for stubborn blockages, such as compacted debris or animal nests deeper within the pipe, the THEWORKS 3/8 in. x 25 ft. Drain Auger is essential. It allows you to physically break apart and retrieve the obstruction that water alone can't dislodge.
What should I do if flushing with the garden hose doesn't clear the clog?
If the garden hose method doesn't work, it's time to use the drain auger. Carefully insert the auger into the vent pipe, feeding it down until you meet resistance. Gently crank the auger to break up the clog, then slowly pull it back, hopefully retrieving the obstructing material. Repeat as needed, flushing with water periodically.
