A Guide on Clearing Clogs from Galvanized Pipes

While it’s less common to find galvanized pipes in new homes, these pipes were the most common type of pipes used as plumbing lines in older homes.

These pipes are manufactured using steel. The steel material is then coated generously with a white or silver finish. Despite having the silver coating, these pipes are still susceptible to corrosion.

Corrosion in these pipes is one of the main causes of their frequent blockage. Once the interior walls of the pipe corrode, the rust roughens the walls.

Consequently, foreign objects, gunk, and bio-film find a perfect place to get stuck once lodged inside. They build up over time and block the pipe.

Luckily, if your galvanized steel pipes are clogged, you can unclog them yourself with basic supplies and tools.

Step 1

Scoop all the water that may be stagnating in the toilet bowl, bathtub, or the sink. Use a cup or any other small container to scoop out the water.

Pour the water into a bucket as you scoop it. In case the tub or sink has a stopper, pull it out to fully access the drain opening.

Step 2

Boil some water and pour it into the tub or sink until it rises up to two inches. In case the clog is in a galvanized sewer line that drains wastewater from the toilet, then pour the hot water down the toilet bowl.

It’s necessary for the affected drain opening to have water over it for plunging to work.

Step 3

Grab a plunger by your hands and place it firmly over the sink or bathtub drain opening. In case the problem is with the toilet, then work with a plunger meant for the toilet, preferably a ball plunger.

A ball plunger is designed in such a way that it seals against the toilet drain opening better than a regular cup plunger.

Work the plunger upward and downward to push water forcefully through the drain pipe. The pressure created by the water as it rushes down the galvanized steel pipe may dislodge the clog.

Step 4

Continue plunging the drain until the clog is dislodged from the pipe. Pour hot water into the drainage. If working on the toilet, use a bucket to pour hot water down the toilet bowl.

In case the water is draining normally, it’s a sign that the clog has been successfully cleared. If you’ve plunged the drainage repeatedly without success, then continue to the next steps below.

Step 5

Buy a chemical-based drain cleaner. Pour it down the affected drain. Read and follow the instructions that come with the chemical.

The best option is a drain cleaning chemical that comes with caustic soda or bauxite as the main component.

Step 6

Run hot water in the bathtub or sink for at least 10 minutes to flush the drain cleaner from the drainpipe. In case you’re unblocking the toilet, simply flush it severally to drain the chemical.
