How lengthy do copper pipes final? Relying on their thickness and the pH of the water touring via them, trendy copper pipes ought to final for 20-50 years. Sadly, that doesn’t exclude a pernicious plumbing drawback generally known as pinhole leaking. Pinhole leaks solely happen in copper piping. Beneath the best (worst) circumstances, your copper pipes might develop a pinhole leak inside solely two years of set up.
Copper pipe pinhole leaks are a frequent drawback all around the US. Your copper pipes will spring pinhole leaks when variations in your water’s pH (acid) worth put on away on the inside pipe’s pure defenses towards corrosion. When you use copper pipes (and, frankly, it’s best to), proceed studying to be taught what a pinhole leak is and tips on how to forestall them.
What’s a Pinhole Leak?

Pinhole leaks are usually very small (usually lower than ⅛” huge) and formed like pinholes, therefore the title. They aren’t solely an issue in and of themselves; additionally they symbolize the manifestation of long-term corrosive injury.
What Causes Pinhole Leaks in Copper Pipes?
Because the Maryland Process Pressure notes above, pinhole leaks are brought on by “pitting corrosion.” The Affiliation for Supplies Safety and Efficiency defines pitting corrosion as “a localized type of corrosion by which cavities or ‘holes’ are produced within the materials.“ Pitting corrosion solely impacts a really small portion of a copper pipe, ultimately carrying away materials increasingly more till it falls in on itself as a “pit” or “gap” – which, in flip, turns into a pinhole leak.
4 Causes of Pitting Corrosion in Copper Pipes
Any of those 4 inciting circumstances might trigger a copper pipe pinhole leak:
1. Chemical Injury
That is the more than likely trigger. Your private home water’s pH worth has little to no bearing in your water’s high quality or security, however it can have an effect on your pipes. In its personal investigation of pinhole sized leaks in copper pipes, town of Folsom discovered 4 alternative ways water’s pH worth might work together with its sulfate content material, temperature, micro organism and/or piping steel to supply the circumstances for copper pitting.
Ought to any of those circumstances happen in your pipes, then the chemical response will eat away on the protecting oxide coating that insulates the internal pipe’s steel from the water operating via them.

Broken copper pipes might not possess the identical resistance to corrosion as they need to, which may result in pinhole leaking and different issues.
4. Non-Uniformities within the Steel Construction
That is notably possible in case your pipes had been solely partially retrofitted into your property, ie: if your property makes use of each copper pipes and one other sort of steel for both piping or connective joints. When two completely different metals work together, particularly in a solvent like water, the ensuing pressure can put on away at each. Within the case of copper pipes, this pressure will put on away on the oxide coating inside your pipes and ultimately result in pinhole leaks.
7 Indicators of Pinhole Leaks in Copper Pipes

When you’re certain you’ve turned off the availability however the water meter remains to be shifting, then you might have a leak someplace. For assist figuring out the placement of the leak or help round tips on how to detect pinhole leaks in copper pipes, Mike Diamond is all the time prepared to assist!
How Not to Repair a Pinhole Leak in a Copper Pipe
Earlier than we cowl tips on how to repair a copper pipe leak, let’s take a look at the significance of what not to do. There’s numerous dangerous copper pipe restore recommendation on the market.
