How to get rust out of water pipes

This blog post will answer the question, “how to get rust out of water pipe” and cover topics like how to get rid of rust in plumbing pipes, what causes pipes to rust, and frequently asked questions.

How to get rust out of water pipes?

Rust can get out of the water pipe by Flushing. Flushing the pipes is the easiest approach to remove rust deposits. 

Open 3 or 4 cold water faucets throughout the home and run them at full pressure for roughly 20 mins. This should clean the pipes of rust particles, but if it doesn’t, wait approximately 30 minutes before flushing them again.

How to Get Rid of Rust in Plumbing Pipes?

Rust can be removed from the plumbing pipes by following the guidance given below:

  • Pour 1/2 to 1 cup sodium bicarbonate down the pipe, followed by a cup of white vinegar right away. 
  • Now cover the pipe with a cloth or plug it and let the solution rest for about half an hour. 
  • Remove the stopper and run hot water down the drain. 
  • Repeat as necessary until the pipe is clean.

Rust on gutters, downpipes, and steel rooves is plainly visible and repairable, but it’s a different case when it comes to the pipes that transport water and gas in your home. PVC pipes are commonly utilized in piping systems for newly-built buildings these days, replacing the galvanized iron pipes of the past, although older houses and other structures still have many of these. 

Copper tubing, which has been used in Australian houses for over sixty years, is still in use because they are perfect for transporting water or gas. These copper tubings show almost no signs of aging. Galvanized pipes, on the other hand, are a different matter. On the inside, they corrode and eventually clog.

If your galvanized iron mains pipelines are rusting, the water that flows through them becomes black and tastes metallic, giving you plenty of notice. Although the corroded water is innocuous, it serves as a reminder that you’ll need to hire a plumber and have the pipes changed or cleaned at some point.

Of course, you might not have a warning if you have gas pipes, and leaks can be quite deadly. Gas can begin to seep through pinprick-sized holes long before any rust is visible, and gas leaks can result in explosions.

What causes the rusting of the pipes?

High oxygen concentration causes rusting of pipes.

Internal oxidation is a proven way for oxygen to damage metal. If the oxygen levels in your water are greater than normal, your pipes may corrode over time. High oxygen concentration in your water can, in the end, cause rust in your plumbing pipes.

Rust is an iron oxide that forms when metals such as iron and steel corrode or decompose. It is created by the redox interaction of oxygen and iron in water or moisture in the air. Galvanized pipes are made of iron or steel, then coated with molten zinc to avoid rust. However, when the pipes become old, the galvanizing peels off, and the pipes corrode, finally eating through the metal.

How to remove rust from the outside of the pipe?

There are methods for removing rust from both the interior and exterior of your pipes and restoring their functionality. It’s recommended to hire a plumber for this, but you’ll need the following materials to get started:

Materials Needed
Naval Jelly
Primer and Paint
Paintbrush
Sandpaper
Steel wool
Plastic sheet
Rubber Gloves

Rust from outside of a pipe can be removed in the following way:

  • Turn off the water at the mains and lay the pipe on a tarp sheet. Scrape the surface with a stiff brush to remove as much corrosion as possible without removing too much metal. 
  • The more corrosion you eliminate, the thinner the pipe becomes, which makes it more likely to split or rupture under high water pressure.
  • After you’ve brushed the pipe, use fine-grade sandpaper to massage it in a clockwise direction to ensure it’s dry and clean, and then wipe it clean with a clean towel.
  • After that, you’ll apply Naval Jelly, a rust-removal gel. (Navy Jelly was reportedly used to prevent corrosion from naval ships during World War II, hence the name.) 
  • This substance will eliminate corrosion, but make sure you safeguard your hands by wearing gloves. 

Sulfuric acid, phosphate ester, phosphoric acid, isopropanol, carbohydrates, and water make up the gel. This implies that if you don’t take the right measures, the gel might be harmful. Look at the following:

  • For the sake of safety
  • Use Naval Jelly
  • Apply paints to pipe
For the sake of safety

Follow the safety measures given below:

  • Because Naval Jelly is an extremely harmful and poisonous substance, it must be kept out of the reach of children and dogs.
  • Because the gel is detrimental to the environment, make sure you have a proper way to dispose of it — adding soda ash to the gel will neutralize it.
  • Wear protective equipment and strictly observe all safety recommendations on the gel bottle.
  • Because the vapors are extremely damaging to your respiratory system, Naval Jelly can only be used in well-ventilated areas.
  • If any gel gets on your skin, wash it off right away with soap and water.
  • If you get the solution in your eyes, rinse them with water very away and see your doctor or go to the emergency room.
  • If you accidentally ingest any gel, don’t try to vomit; instead, drink lots of fluids and go to an emergency room very away.
  • Naval Jelly should not be used on fiberglass, chrome, marble, concrete, aluminum, or plastic.
Use Naval Jelly.

Steps of applying Naval jelly:

  • As previously said, make sure you’re using your protective gear, which includes gloves, protective goggles, and a face shield.
  • Apply a large amount of Naval Jelly to the rusted parts of the pipe using the brush, and then use the brush to get into every small crack or bend.
  • Allow the gel to sit on the corrosion for five to ten minutes, during which time it will turn the corrosion into a water-soluble mixture. After fifteen min, the metal will have pockmarks.
  • Wipe the gel from the pipe completely with a clean, moist towel. 
  • Then dry it with a dry clean rag and inspect the pipe for any corrosion that was missed; if there is any, repeat the process.
Apply paints to pipe:

You may paint the pipe to prevent it from future corrosion after you’ve brushed, cleaned, sanded, used Naval Jelly, then washed and cured it. Use a respirator and operate in a well-ventilated location to avoid breathing paints and primers.

Steps of applying paints to pipe:

  • Apply a rust-inhibiting primer to the whole pipe, including the portions that were not corroded; this will stop corrosion from returning to the entire pipe.
  • Let the primer dry completely according to the instructions on the container.
  • The pipe should be painted.

How to remove rust from the inside of the pipe?

Rust can be removed from the inside of a pipe by following the steps given below:

  • The first step is to double-check that the water supply is still turned off at the mains. Water damage to your house and possessions will be avoided as a result of this.
  • To clear the obstruction in the pipe, use a metal pick to pry out the chunks of corrosion if the corrosion hasn’t solidified and the blockage is reachable.

Note: If the obstruction is in a pipe that transports potable water, gardening water, or food preparation water, do not proceed to the following step. (If this is the case, a plumber will be required to repair the pipe or a piece of it.)

  • CLR, can be used if the rust causing the obstruction is unavailable. Put it down the pipe, where it will loosen and disintegrate the clog over time if the pipe is horizontal. If the corrosion is at the knobs, spritz it with CLR and let it sit for a few minutes before cleaning it away with soapy water.
  • Reattach the pipe to its original location, turn the water back on at the mains, and open the tap after the corrosion blockage has been cleared. The water will be brown at first, but keep running it for a few minutes until it clears up.

What Causes Corrosion in Pipes?

Pipe corrosion can be caused by a variety of factors. Some of these issues are easy to address, while others may be avoided. The five most prevalent reasons for pipe corrosion are listed below:

  • Corrosion occurs when the PH level goes below a particular point in copper pipework.
  • When oxygen is coupled with water, it causes rust, which is damaging to metals. Corrosion will nibble away at your pipes if you have enough air in them.
  • Corrosion can also be caused by chemical build-ups, such as calcium.
  • According to studies, the higher the water temp, the more harm it can cause to your pipes by corroding them.
  • Finally, rust can be caused by abrupt pressure fluctuations or variations in water direction.

Using acid-based clog repellents (such as Drain-O) and dumping grease and oil down the sewer are two more sources of pipe corrosion.

What’s the Best Way to Clean My Pipes?

Many individuals employ the option of cleaning their pipes at home. When coping with minerals and calcium build-up on the exterior of your pipes, this method is extremely helpful (not too deep within your piping system). 

Here’s a great solution:

  • Any remaining freestanding water should be removed.
  • 1-gallon pure white vinegar poured down the drain
  • Allow half an hour for the vinegar to dissolve the calcium.
  • Scrape as much of the accumulation as possible with a long-handled scrubbing brush (ideally plastic).
  • Vinegar aids in the removal of calcium build-up by letting the acid dissolve. If you have hard water, you should do this once a month, or until you notice symptoms of build-up.

Frequently Asked Questions(FAQs), “How to get rust out of water pipe?”

Is rust in water pipes harmful?

Yes, rust in water pipes is harmful. Corrosion, no matter wherever it originates from, is extremely damaging to your pipes. Letting rusty water enter via your water main is terrible for each and every pipe in your house because it puts them at risk of blocking and causes them to decay/corrode quicker.

How do you remove rust from steel pipes?

  • Spread a thin layer of naval gel to all of the rusted surfaces of the pipe with a sponge. 
  • Let the naval gel sit for the period of time suggested on the manufacturer’s guidelines, depending on how much corrosion is present. 
  • The naval gel is sold at hardware and home improvement stores.

How do you fix rusty well water?

A water softener is one of the best ways to get rid of corrosion. Water softeners add salt to your well water, which helps to eliminate corrosion and other contaminants that are difficult to filter out. Combining an improved product with a water softener is another option.

Is it OK to bathe in rusty water?

Is it safe for me to take a bath in rusty water? When iron oxidizes, rust develops. Because it is not digested, this molecule is typically not harmful to healthy skin. Showering with rusty water on a daily basis can degrade the condition of your hair and skin over time, making them dry.

What is the best homemade rust remover?

White vinegar may be used to effectively remove corrosion. Rust interacts with vinegar and eventually disappears. Simply immerse the rusted metal object in white vinegar for a few hours before wiping the rust away.

Can Coke remove rust?

What is it about Coca-Cola that makes it such an excellent cleaner? Coca-Cola is carbonated, allowing it to break down metal oxides and remove corrosion on a wide range of metals and alloys. Its rust-busting ability is aided by phosphoric acid, while its stain-removing ability is aided by citric acid.
