Cast iron pipes used to be the go-to option for water transportation due to their durability and strength. Although cast iron pipes are no longer commonly used to prevent erosion, some homes still have them.

Old cast iron pipes usually get dirty and or blocked over time, and this can lead to obstruction in water flow and more serious problems. However, in this article, you will learn how to clean your cast iron pipes and keep them working for a long time.

Why You Should Clean Your Cast Iron Pipes

Cast iron piping and ductile iron pipe were previously commercially used for drain, waste, and vent lines in residential buildings. However, cast iron pipes are more vulnerable to pipe corrosion than modern materials, such as plastic PVC pipes. Rust further damages the pipes, and fragments can seep into your water supply, including your drinking water.

You probably think about how much it will cost to have your entire cast iron drainage system replaced, but you don’t necessarily have to. Cleaning the pipes properly can prevent problems and increase their durability.

One of the best tools for cleaning cast iron pipes is a cast iron pipe descaler. But, if you don’t have a descaler, you can use vinegar and baking soda solution.

Apart from cleaning the exterior surface of the pipes, you can establish a plumbing maintenance program with a safe and organic enzymatic drain cleaner.

Using a Cast Iron Pipe Descaler

A cast iron pipe descaler is a cleanser that eliminates mineral deposits and other debris from your cast iron pipes. Pipe descaling is not difficult at all, and it’s effective. You can even do it yourself if you have the equipment. Check for non-corrosive and non-toxic cast iron cleansers made with organic ingredients.

How To Eliminate Clogs from Cast Iron Pipes

While cast iron pipes are extremely durable, they are susceptible to clogs. Although several methods are used in unclogging cast iron pipes, the most effective method usually depends on the location and extent of the clog.

Most of the time, a plunger or plumber’s snake can unclog localized, minor obstructions in your drain line. We advise using these tools because, when used correctly, they won’t harm older pipe materials. Naturally, this is the reason it’s so crucial to select the appropriate equipment for the job.

You might need a motorized auger or chemical drain cleaners if the obstruction is more severe.

An electric snake enters your drain similarly to a drain snake, except it extends deeper and produces more power.

If the clog is beyond the reach of the electric snake, you might wish to choose a chemical drain cleaning.

You must be careful not to choose a drain cleaner that will damage the cast iron pipes.

Can I Use Sulfuric Acid Drain Cleaner to Clean My Cast Iron Pipes?

Homeowners frequently use sulfuric acid drain cleaners to dissolve clogs in cast iron pipes and remove them. While sulfuric acid can dissolve blockages, it is also extremely corrosive. It is not advised to use it on cast iron pipes.

Cast iron pipes’ protective covering can be eaten away by sulfuric acid, causing leaks and, finally, the pipe’s breakdown. It is advised to avoid using drain cleaners with sulfuric acid if you have cast iron pipes. There are alternative methods for unclogging clogs that won’t harm your pipes.

How To Clean Your Cast Iron Sewer Pipes

Since your cast iron sewer pipe is underground, accessing it is very challenging. You can hire an expert to perform a sewer camera examination to identify the root cause and exact position of the obstruction and then, based on the findings, choose the best option.

The best approach to clean cast iron sewer pipe (see above) is to use an extremely high-pressure water jet, while there are a few other techniques that can be employed as well.

This will clear any accumulation on the pipe’s walls and aid in clearing any jams that could have developed. Another choice is to use a revolving brush; however, if not utilized properly, this might lead to pipe damage.

It is preferable to engage a professional plumbing firm to clean cast iron sewer pipes if you are unsure how to do it yourself.

Rather than wasting the money on cast iron repair, in some extreme circumstances of significant corrosion and degradation, cast iron pipes might have to be removed using trenchless sewer replacement techniques.

Depending on the exact situation, the two primary trenchless repair techniques are pipe bursting and CIPP pipe relining. Both times, fresh material will be used instead of cast iron pipe.

Trenchless pipe replacement and hydro jetting both require the expertise of a qualified sewer and drain specialist. Cast iron pipes can, however, last a long time without being changed with the right upkeep and care.
