Plumber's snake: Bring a plumbing snake or auger onto the roof. Run it down the vent until you reach the obstruction. Turn the crank on the plumbing auger to cut through and remove the clog.
You may need to hire an HVAC technician to use brushes and vacuums to thoroughly clean out the inside of the duct. For more stubborn clogs, it may even be necessary for your HVAC technician to cut away part of the duct, remove the clog, and then patch the hole.
Every few years, assuming you can get up on your roof safely, you should put a garden hose down the roof vent pipe and run water down the pipe for a few minutes to wash out any accumulated dust, tree debris, or even bird poop. If you do this, be sure you put sentries within the house to spot any leaks.
Put the glass with the handpiece into the water-filled ultrasonic bath. If possible, set the temperature to 50°C (122°F) and activate the ultrasonic power at your usual setting for approximately 15 minutes. Rinse the AIRFLOW® MAX handpiece with tap water.
An easy indication that your air ducts are dirty or clogged is when the system turns on, you may see a cloud of dust coming out the air vents. You can double-check this by turning off the HVAC system and waiting a few minutes after it has shut down.
Using a cloth, clean the exhaust tip, then for inside the exhaust, use a hard bristled brush, cleaning as deep in the tail pipe as you are able to. Applying a degreaser will help in breaking up carbon deposits and rust. Using a dry cloth, apply a degreaser to the inside and outside of the exhaust.
In the walls, vent pipes run straight up and down and should be located near the kitchen and bathrooms. Note where the pipe enters from the ceiling. If you have a two-story home, go upstairs to locate the pipe. You can verify whether a pipe is a vent pipe by listening as someone flushes the toilet.
It will look like a vertical pipe running through the roof. The vent pipe works hand in hand with the drainage pipes. When the drainage pipes carry waste out of your home, the vent pipes supply fresh air to the plumbing fixtures, so they can repeat the process and continue moving waste out of your home.
Debris blocking the vent won't allow air to get inside and push the water out of drainage pipes. Any drain in your home that takes forever to drain can be due to a blocked vent. This can be your bathtub or shower drains, sink drains, or toilets.
Step 1: Take out any debris or anything blocking the pipe that's reachable with your hand. Step 2: If you can see any blockages around it but can't reach them, use a plumber snake and run it down the pipe.
Gurgling Noise: Unusual gurgling noises emanating from your plumbing fixtures, especially after flushing the toilet or draining the sink, can indicate a vent blockage. Gurgling toilets and drains are a result of air being trapped in the plumbing system, struggling to find an escape route.
Even one blocked vent in the home can cause an inefficiency in air flow, which means your HVAC system will likely have to work harder to achieve the desired temperature. The result may be a home that is riddled with uneven temperatures from room to room.
Lubricate the shutter lever
Once the register is clean, locate the pivot point for the shutter lever and apply a drop or two of light machine oil. Manipulate the lever until it opens and closes smoothly; do not use too much lubricant and avoid the use of spray penetrating oils that will only attract and hold dust.
Vinegar And Baking Soda
This is a safe, natural way to break up clogs in drains. Start by pouring one-third of a cup to one cup of baking soda into the drain and let it go as far down as possible. Also pour in an equal amount of vinegar. The mixture will bubble and foam as it works to clear up the clog.
If you've got a completely blocked waste pipe, fill your sink up part way and place the cup of a sink plunger over the plug-hole. Follow that by stuffing a damp cloth into the overflow to prevent any pressure loss. Pump the plunger up and down vigorously – go on, give it some welly!
Natural cleaners
Try pouring hot water down the drain, then follow it with one cup of bicarbonate of soda and a cup of vinegar. Leave it for ten minutes, then chase it with more hot water. A combination of the hot water and the natural cleaner mixture can break blockages up.
