How to Use an Air Compressor on a Clogged Sink

  1. Gather supplies.

  2. You can use a commercially created device that attaches to an oil-free air compressor such as the BAAM! drain blaster or you can create one using tubing.

  3. When creating a homemade tubing device to use to clear out the clog, start with one and one quarter inch hose. Using hose clamps clamp the one and one quarter inch hose to smaller three-quarters or one-inch hose. Then clamp the smaller hose to an air hose quick connect that will attach to your compressor hose. Make sure that all the clamps are tight and will not blow apart when pressure is put on it. While working on this part of the project. Plug in the air compressor so it can be building air in the compression chamber.

  4. Push the 1 and quarter inch tubing into the clogged sink. Attach the quick connect onto the compressor and detach it quickly. Blasting fifty to sixty-five pounds of pressure into the sink. This should blast apart the clog in the sink using compressed air.

  5. You will still have to use bleach or any other kind of chemical sink clog remover to completely clear the clog. This will also help clear the clog out and make the edges of the piping more slippery and less likely to re-clog.

  6. You can use any type of oil-free air compressor when using the homemade device. One that has been utilized before and worked well was a craftsman 120-volt air compressor. You also need to be sure that you are plugging any holes that may be in the sink such as overflows or vents in the tubing. Also, do not utilize much over 65 PSI as to not blow apart your tubing below your sink. Then you will have bigger problems than just a clog! Using a compression chamber is a very successful way to unclog sinks and is very effective.
