DIY Solutions
The clogs on the cast iron drain pipe may be minor, if so, try incorporating these DIY solutions to unclog it.
1. Plunger
This is the most common method to fix minor clogs not only for cast iron drain pipes but for any home chore. To use a plunger, start by covering the overflow drain using a wet cloth. Then, place the plunger over the drain opening and plunge the tool up and down to make suction. Continue the suction until it dislodges any blockages. This will also restore the smooth flow of water on the cast iron drain pipe.
2. Plumbing Snake
Another traditional method is by using a plumbing snake. You can buy this tool at a local hardware store and it’s recommended to get one with blades. You may also run some hot water down the cast iron drain pipe to help soften the debris before the procedure.
Start by inserting the end of the tool into the clogged drain. Then, twist it clockwise as you push it further down the pipe. This method helps by breaking up the clog and descaling the blockade.
3. Baking soda and vinegar mixture
This simple solution involves the mixture of parts that you can find in your kitchen. Baking soda and vinegar mixture are both substances popular for their foaming action. They can also break down minor pipe blockages if you let them sit for an hour or more.
Begin by pouring hot water on the clogged cast iron drain pipe. Once done, pour a half cup of baking soda and half a cup of vinegar mixture.
Chemical Drain Cleaners for major clogs
4. Drain cleaners
First, remember to choose a chemical drain cleaner exactly designed for cast irons. Otherwise, there’s a high chance that you’ll do more harm than good and end up spending more money.
It’s also important to take safety cautions such as wearing high-grade protection gloves and goggles to shield yourself from harmful chemicals. Assuring that the area is well-ventilated will also prevent the accumulation of fumes.
Refer to the packaging of your chosen chemical drain cleaner. Then, pour the recommended amount straight to the clogged drain. Once done, allow the product to sit for the suggested duration. This will let the chemicals have enough time to dissolve the clog.
Finally, flush the drain by pouring hot water into it. This will remove any excess residue and restore a smooth flow.
5. Sodium Hydroxide
Sodium Hydroxide is a powerful chemical compound to unclog cast iron drain pipes. It’s also a complete favorite tool for clogged shower drains and for good reason. Well, it’s because it can dissolve hair easy. Sodium Hydroxide is cheap but can only be used for emergencies. Meaning, it may not be suitable for a long-term fix.
You can follow the same step as pouring a chemical drain cleaner (solution number 1). Remember to follow the same safety precautions too.
Hydro jetting: A professional solution for stubborn clogs
Hydro jetting is a process that uses high-pressure water to remove debris, grease, and other blockages from pipes. This method is effective in cast iron because it can breakdown clogs piece by piece.
Although hydro jetting is mainly performed by professionals, it’s a non-invasive method which means there’s no need for extensive digging or disruption in your property. It can also clean the entire length of the pipes!
The process of hydro jetting starts by putting a specialized nozzle in the clogged drain. The nozzle will release a powerful stream of water at high pressure. Finally, it will blast away any buildup or obstruction along the way.
Other fixes

Picote Cleaning can break up the blockage physically, leaving you a clean and clear pipe. Picote cleaning is also known for its comprehensive and long-lasting solution. Though only done by professionals, many have said that it’s worth the investment.
