Back-Flush the Faucet Hose — Flush the Vent with a Garden Hose

How to Clear a Clogged Plumbing Vent Stack · Step 3 of 5
In this video
If the flow is still low after cleaning all other components, the main flexible hose is likely clogged. To clear it, use a pump sprayer filled with water to create pressure. With the faucet handle in the 'on' position, insert the sprayer nozzle into the end of the faucet hose and spray water backwards through the line. Have a partner hold a cup under the faucet base where the supply lines connect to catch the water and debris that is flushed out. This reverse pressure should dislodge the final obstruction.
Goal: Drain Unclogging
- This is a great last-resort technique before deciding to replace the entire faucet, as the clog is often in an inaccessible part of the hose.

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.
