How Do I Clear the Main Drain Line in My House?

How to Unclog a Main Drain Line: Easy DIY Guide

• Locate the Main Cleanout

The cleanout is a capped pipe that provides access to the main drain line. It's usually found in the basement, crawlspace, or outside near the sewer line. Look for a round, metal cap with a threaded plug. You can use a wrench or pliers to remove the cap carefully.

• Insert the Auger

An auger, also known as a plumbing snake, is a long, flexible cable with a cutting head. Insert the auger into the cleanout pipe and feed the cable into the drain line. Begin to turn the handle to advance the auger into the drain line.

• Break Up the Clog

You may feel some resistance as you feed the auger into the drain line. Continue turning the handle to break up the clog. You may need to feed and retract the auger several times to clear the blockage completely. Main drain clogs can be stubborn at times, so it’s a good idea to give it a try a couple of times.

• Retrieve the Auger

Once you feel the auger pass through the clog, slowly retract the cable, removing any debris that comes out.

• Flush the Drain Line

Turn on the water supply to the house and allow water to flow through the drains to flush out any remaining debris. Check all drains in the house to ensure they are draining properly.

When to Call a Plumber

While you can attempt to clear a main drain line clog yourself, there are instances when calling a professional plumbing service is advisable. If you’re dealing with persistent clogs, you should consider hydro jetting your main drain line to get rid of stubborn blockages and restore optimal flow. Reach out to a professional company specializing in hydro jetting for a thorough cleaning and inspection of your main drain line.

However, if you start to notice signs of a blockage, you’ll want to call a professional plumbing service before things get out of hand.
