Your plumbing vent pipe is an integral component of your home’s plumbing system. If it becomes clogged, it can cause a host of issues.
For instance, a clogged plumbing vent pipe can cause your toilet or sink to drain slowly or not at all, as well as allow foul odors into your house.
Identifying the Problem
When your plumbing system is working optimally, it should quickly and efficiently drain water away from your home. This task is carried out by drainage pipes connected to vent pipe stack (the opening on your roof), which pushes waste away from your residence into either a city sewer or septic tank.
Clogged vent pipes can lead to a variety of issues, so cleaning them is essential for maintaining your home’s plumbing system. Here are some warning signs that there might be an issue:
Sputtering or Gurgling Sounds – Similar to when a milk jug isn’t properly drained, these noises indicate there’s not enough air entering the pipe and thus water won’t flow smoothly.
Rotting Smells – Another sign of a blocked vent pipe are unpleasant smells. Not only that, but these could also be hazardous as the foul odors may cause nausea and dizziness if inhaled; thus why it’s essential to contact a plumber right away if these symptoms appear.
Other signs that your vent pipe is clogged include slow drains, unpleasant odors and strange noises. If all three occur simultaneously, then you can be certain the issue lies within your vent pipe.
Bird nests and rodents can clog your vent pipes, so it’s essential to check them periodically for new nests or other debris. If you spot a nest or another type of animal causing blockages, remove it promptly.
Tree roots can cause significant damage to your vent pipe, so if you notice any new or existing ones near it, call a professional for removal.
If the problem persists even after cleaning your vent pipe, it could be due to an issue with the pipes themselves. If after clearing out the vent pipe and it still clogs, corrosion in the pipes is likely the source of this corrosion that cannot be fixed.
Your plumbing vent is an integral component of your home’s plumbing system, so it needs to be regularly inspected and maintained. Clogged vent pipes can lead to more serious problems and cost you money in the long run; that’s why it’s so essential to learn how to identify and resolve problems with your vent pipe efficiently.
Using a Snake Drain
Your vent pipe is an integral component of your home plumbing system, keeping out sewer gases and odors while helping keep water and waste flowing. However, it can become clogged with debris over time leading to problems.
Unclogging a vent pipe with a drain snake is an effective solution. These tools can be rented from your local rental store and provide the ideal solution to fixing a clogged sink at home.
To use a snake, insert it into the drain opening beneath your sink or tub. You may have to take apart the P-trap for this task, or simply remove the cap at the top of the pipe and insert your tool.
Once inserted, it’s essential to move the snake slowly and carefully. Doing so avoids kinking of the cable as you try to force it through your drain pipe.
To avoid this problem, begin by extending the cable only a few inches at a time and gradually moving it until you feel it reach the clog. Once inside the drain, continue extending and rotating until you break up any clumps.
Depending on the size of the clog, this process may take some time. In some cases, multiple rounds of snaking may be required to completely clear it away.
The type of clog you have will dictate which drain snake type you use. Hair clogs, for instance, require the metal corkscrew end of a snake.
Cooking fat, soft materials, and other hard substances can cause the corkscrew end of a snake to snag. That is why it is essential to clean out the corkscrew end before using it on a clog.
When using a drain snake, it’s important to remember that some clogs may be too dense for even an ordinary hand snake to penetrate. If the obstruction is large or stubborn, you may need to rent or call in a power auger or hire a plumber for assistance.
Using a Garden Hose
One way to unclog a blocked vent pipe is with a garden hose. Set the nozzle to its highest setting and spray directly into the pipe; this should push any debris out and you may even hear it flush as water passes through.
Another option is to manually remove the clog from your roof using a snake drain or plumber’s auger. This approach is safer than climbing up onto it yourself.
However, you must exercise caution as a clogged vent can pose serious hazards to yourself and your property. Thus, calling in an expert who follows safety protocols and can complete the job quickly and efficiently is recommended.
Prior to beginning any repair work, it’s essential to locate the vent and identify its issue. Doing this will save time and money in the long run.
Begin by clearing away any leaves or nesting materials that might be clogging the vent pipe. Doing so will restore airflow to the pipe and prevent future issues.
Next, you’ll need a ladder and flashlight. Make sure the ladder is sturdy and placed on solid ground so you can climb safely.
Once you reach the peak of your roof, use a flashlight to shine down onto the vent pipe and check for any accumulated debris or blockages. This could include branches, trees or nests that birds are building in the area.
To do this safely, you’ll need a pair of rubber-soled shoes and safety harness to hold onto as you climb up the roof. Additionally, you will need a screwdriver and garden hose.
In addition to your usual tools, you’ll need a 10 or 20 foot plumbing plunger to break up any stubborn clogs inside the pipe. This will help get it out and onto the ground so you can clean it thoroughly.
If the clog is particularly stubborn, you may need to employ a sewer jetter. This method requires more time and effort than using a garden hose but is much more effective.
Using a Sewer Jetter
A clogged vent pipe could be slowing down your drains or emitting an unpleasant odour that resembles sewage. Either way, cleaning the vent pipe is important to keep your home’s plumbing system functioning optimally.
Prior to beginning, make sure you have access to your vent pipe through either a cleanout pipe on your roof or an opening in your home’s basement wall. If not, drill a hole in the cast iron vent stack so you can access your home’s sewer line. With everything clear, use a sewer jetter down the pipe to flush out any debris that has built up inside of it.
Next, set the nozzle to “jet” or “full.” If there are no visible obstructions, spray water directly into the vent opening.
This method may clear away years of debris that has built up inside the pipe. Furthermore, jetted water may push any blockage out of the vent and into your main sewer line. If however, your clog has been present for some time, more aggressive measures may be necessary.
You could also try hydro jetting, which is an aggressive cleaning technique that uses pressurized water to blast away clogs from inside pipes. This should only be done by a qualified plumber but you can rent a water jetter for less than $200 from most rental yards.
Sewer jetters offer a less invasive alternative to using drain snakes for cleaning out your sewer line. Plus, regular use of this technique will keep your home’s plumbing system functioning optimally.
If you must use a drain snake, make sure to wear gloves to protect yourself. Be sure to rinse your hands thoroughly afterward as well.
Furthermore, you should take great care not to snag the sewer jetter hose on your gutters and flashing as you work. Ideally, have someone nearby who can guide the hose so as not to snag it on your home’s siding.
