How To Clean Bathroom Pipe Blockage Using Lye?

Step 1. Purchase A High-Quality Commercial Lye labels lye as the “ultimate de-clogger” for bathroom pipes. In chemistry, lye is known as sodium hydroxide, and it can be prepared at home. However, raw lye can be damaging to pipes. Therefore, we recommend buying a good quality commercial lye like the Comstar Pure Lye Drain Opener.

Step 2. Read The Instructions

Lye is a powerful alkaline solution, so it can cause severe damage to the piping if not used in moderation. Read the instructions on the label attentively to find out the suitable usage amount.

Step 3. Pour & Flush

Drop the appropriate amount of lye into the toilet or drain. If you want, you can try unclogging with a plunger first. The lye will wash out the residuals. However, you can skip the plunging part and apply lye directly. Leave it for the amount of time prescribed on the instruction label. After that, flush with water.

How To Clean Bathroom Pipes Using Plunger?

Step 1. Prepare The Plunger

Just like we did while cleaning bathroom drain pipes, we will apply petroleum jelly along the edges of the plunger’s suction cup. It will enhance the seal and allow the plunger to exert a superior pull.

Step 2. Put The Plunger On The Pipe Opening

Undo the drain screws and take off the drain covering. This will expose the opening of the pipe. Place the suction cup of the plunger on it and start pulling. To improve suction, you can keep the floor submerged. A wet suction cup would impose a stronger grip.

How To Clean Bathroom Pipe Blockage With Drain Snake?

Step1. Insert The Snake Into The Pipe

A plumber’s snake is a sophisticated plumbing tool that can help you in situations like cleaning bathroom vent pipes and other plumbing emergencies. Uncap the drain and put the snake inside. Keep on turning the handle so that the auger uncoils.

Step 2. Continue Probing Until You Find Obstruction

Continue uncoiling the auger until it reaches the blockage. Once you sense an obstacle, you would have to put on some extra pressure to maneuver the bent regions on the pipe. In the linear portions of the pipe, the snake will navigate effortlessly before hitting the clog.

Step 3. Rotate The Snake To Break The Buildup

When the snake touches the blockage, start rotating it. In doing so, the head of the snake will push through the obstruction and break it up. In the case of hairy clogs, the tip will capture it. If you feel the snake is not dissolving the clog, pull it out and see whether or not it’s stuck with the snakehead.

Step 4. Flush

Run water down the pipe to remove the remaining dirt. If the water doesn’t pass through smoothly, reenter the snake and probe for further blockages. The Ridgid GIDDS-813340 41408 can be a good pick if you are looking for a plumber’s snake.

Step 2. Boil The Water

Fire up your stove and put the pot or kettle on top of it. Within a few minutes, the water should start bubbling, which means the water has been boiled. Are you using an electric kettle? If you are, then make sure the base is dry before you switch it on. Otherwise, you might get an electrical shock.
