How to Unclog a Toilet With a Drain Cleaner

A clogged toilet is an intimidating household foe. You never quite know what may be blocking the toilet, and flushing can lead to a bathroom flood that can damage your flooring. For severe clogs, you will probably need to use a closet auger to clear out the drain, but for minor backups, combining drain cleaner and your plunger may solve the problem. Because of the chemicals used in drain cleaner, always use caution when using drain cleaner.

Step 1

Plunge the toilet beforehand to try and unblock the clog in your toilet. Place the plunger over the hole in the bottom of the toilet and make quick plunging thrusts. This will push air and water through the toilet and help dislodge the clog. Sometimes toys and other objects will block the toilet, and a little plunging may provide enough pressure to dislodge the object.

Step 2

Pour the recommended amount of drain cleaner into the toilet. Read the label carefully, as each different brand of drain cleaner will differ.

Step 3

Allow the drain cleaner to sit in the drain for at least thirty minutes to give it time to work on the clog. Do not plunge the toilet during this time.

Step 4

Check the toilet after 30 minutes to see if the clog has cleared by attempting to flush the toilet. Make sure your plunger is handy; if the clog is still present, you will need to plunge the toilet in order to keep it from overflowing.

Step 5

Plunge the toilet again if the clog was not completely removed by the drain cleaner. You may have loosened the clog enough that plunging could dislodge whatever is clogging the drain.
