The primary cause of pinhole leaks is the composition of the water flowing through your plumbing system. Hard water—high amounts of dissolved calcium and magnesium—or water that is too basic (low pH) or too acidic (high pH), can all contribute to copper pipe corrosion.
How do you prevent pinholes in copper pipes?
A few ways to prevent pinhole leaks include knowing your pipes’ age, reducing the water velocity, checking the fittings, and installing a water softener system.
Are pinhole leaks in copper pipes common?
Pinhole leak in copper pipe is a common problem all over the US. Your copper pipes spring a pinhole leak when variations in your water’s ph (acid) value wear away at the inside pipe’s natural defenses against corrosion.
Can you fix a pinhole leak in a copper pipe?
Because pinhole leaks are small, the easiest repair method is to fill them with epoxy putty. Repairs made with epoxy putty are long lasting but not permanent. To reinforce the pinhole pipe repair and turn it into a permanent solution, you can overwrap the putty with a pipe repair bandage.
How do you stop copper pipes from corroding?
Install a phosphate feeder before the copper piping. Phosphate will coat the piping and reduce or slow down the corrosion effects by coating the piping’s interior surfaces with phosphate and causing an insulation surface to be built up.
What is the life expectancy of copper plumbing?
Copper. This is the most common metal used today for plumbing pipes, and it has been in common use from the 1970s onwards. Copper pipes will usually last for more than 50 years.
How can you tell if a copper pipe is leaking?
The most common sign that your copper pipes are leaking are a bluish-greenish stain on the outside of the pipe. This is a strong indication that your copper pipe has developed a pinhole leak. The green color of the copper pipes in your home is called “patina.” There are many reasons why you might see this.
How much does it cost to fix a pinhole leak in a copper pipe?
The pipe thickness can also impact repair costs. According to a Thumbtack pro in Poway, CA you can expect to pay $150 to repair a pinhole leak on a half-inch copper line and $240 for a 1-inch one—including labor and materials to cut out the faulty piece of pipe and solder in the new pipe.
How do you fix a leaking copper pipe without soldering?
Copper and PEX piping are the preferred alternatives and can be used in place of the leaking pipe by using sharkbite couplings. Start by turning off the main water line to your home and bleeding the system of water so you don’t get drenched when opening up the pipe. Then use a pipe cutter to remove the leaking section.
Does Flex Seal tape work on copper pipes?

What can I use to seal a leaky pipe?
Use epoxy putty or pipe putty as a temporary fix to a leaky pipe. Pipe putty is designed to harden at room temperature and seal the hole or crack. Turn off the water supply line in the house.
How do you stop the oxidation of copper?
Coat the copper item in a protective coating to prevent future discoloration. Coat the item in beeswax or carnauba wax. Dip the soft cloth in the wax and apply it to the copper surface. Buff with a clean soft cloth.
Why are my copper pipes corroding?
The presence of oxidizing acids; heavy-metal salts, sulfur, and ammonia; and a number of sulfur and ammonia compounds can cause corrosion to set in. Water that comes from a well is much more likely to contain these materials and put copper lines in jeopardy—but it can occur in the civic water system as well.
What causes copper erode?
Water moving through a pipe at unusually high velocity can wear away copper from the interior of the pipe. If the pipe ends weren’t properly reamed smooth prior to soldering, the raised burrs inside the pipe can cause local turbulence, called erosion corrosion, which will corrode the pipe.
Should copper pipes be replaced?
You should replace any copper pipe that is showing signs of damage or deterioration, regardless of its age. If your water is chronically acidic, copper piping might not be the best choice for your home. Water that normally has a pH greater than 6.5 won’t deteriorate your copper pipes.
