How To Drain Toilet Bowl: A Step-By-Step Guide

If you’re experiencing problems with your toilet bowl, such as a clogged drain or a leak, you may need to drain it to perform repairs or cleaning. In this article, we’ll show you how to drain toilet bowl in a few easy steps.

Step 1: Turn Off the Water Supply to the Toilet

Before you begin, you’ll need to turn off the water supply to your toilet. Look for the valve behind the toilet and turn it clockwise to shut off the water flow.

Step 2: Flush the Toilet

Flush the toilet to remove as much water as possible from the bowl. This will make it easier to drain the remaining water.

Step 3: Remove the Remaining Water

To remove the remaining water from the toilet bowl, you can use a plunger or a wet/dry vacuum. If using a plunger, place it over the drain hole and pump it up and down until the water is gone. If using a vacuum, use the hose to suction out the water.

Step 4: Disconnect the Water Supply Line

Next, you’ll need to disconnect the water supply line from the toilet tank. Use a wrench to loosen the nut that attaches the line to the tank, then pull the line away.

Step 5: Remove the Toilet Tank

Remove the tank from the toilet bowl by unscrewing the bolts that hold it in place. Once the tank is removed, you’ll have better access to the bowl.

Step 6: Remove the Toilet Bowl

To remove the toilet bowl, unscrew the nuts at the base of the bowl and lift it up and off the floor. Be sure to have a helper to assist you with this step as the bowl can be heavy and awkward to handle.

Step 7: Drain the Bowl

Once the bowl is removed, you can drain the remaining water by tilting it over a bucket or drain. Allow the water to completely drain out before proceeding with any repairs or cleaning.

Step 8: Clean the Bowl

With the bowl drained, you can now clean it thoroughly. Use a toilet bowl cleaner and a scrub brush to remove any stains or buildup.

Step 9: Inspect the Drain

While the bowl is removed, inspect the drain for any signs of clogs or damage. If necessary, use a drain snake to clear any blockages.
