The Most Frustrating Type of Leak is Often the Least Noticeable

Pinhole leaks in plumbing systems are a common and frustrating type of leak many homeowners experience. A typical pinhole leak is about the size of the tip of a pen, however, the potential damage caused by these leaks can be substantial. Because most pinhole leaks occur gradually and are not easily seen, they often do not get noticed until there is evidence of water damage such as discoloration of walls or ceilings, mold growth, or structural damage.

Knowing how to fix a pinhole leak, will allow you to quickly respond to this type of damage to your home and keep it from becoming worse.

Most people find out about pinhole leaks while frantically looking for “plumbing services near me”. However, being aware of the common signs and causes of pinhole leaks will allow you to notify a local plumber before the damage gets severe, thus conserving your money and minimizing damage to your home.

What Is A Pinhole Leak?

A pinhole leak is a very small hole in a pipe. The majority of pinhole leaks occur in copper pipes, and the reason for most of them is corrosion or other types of chemical reactions occurring within the pipe itself. Although the opening of a pinhole leak may be small enough to be difficult to see, continued flow of water into the pipe will create extensive damage behind walls, ceiling or under flooring.

Unlike bursting pipes, pinhole leaks normally occur gradually. Where a small leak at first will eventually grow into an open flow of water, which will increase your monthly water bill, and could also result in a moisture issue, that is concealed from view.

Causes Of Pinhole Leaks

Knowing the reason for the pinhole leak will assist in determining the proper method of repair.

1. Pipe Corrosion

Corrosion of copper pipes occurs due to water chemistry; excessive amounts of minerals, or acidic content, in the water flowing through the pipe. If the pipe is weakened enough by the corrosion, a small hole will eventually begin to form in the pipe.

2. Incorrect Water Flow Rates or Pressure

High velocity water flow rates or pressures can erode the interior surface of a pipe, creating thin areas, which ultimately form pinholes.

3. Bad Workmanship or Sub-Standard Materials

Poorly sized pipes, low-quality piping materials, or poorly installed piping can all add to stress on the pipes. A local plumber can tell you if the improper workmanship was what created the issue.

4. Old Plumbing Systems

Older homes have a greater chance of having pinhole leaks because the original piping is probably beyond its normal life expectancy.

Common Signs Of Pinhole Leaks

As pinhole leaks are usually hidden from view, you need to be aware of the following indicators of a pinhole leak:

Increased Water Bills

Water Stains On Walls Or Ceilings

Musty Odors

Decreased Water Pressure

Sound Of Running Water When Fixtures Are Off

If you notice any of the above indicators, searching for “plumbing services near me” as soon as possible will likely minimize additional damage to your home.

Why DIY Repairs Won’t Be Enough

Using DIY remedies, such as pipe clamps, epoxy, or tape, may temporarily halt a leak, but they won’t resolve the root cause of the problem. Since corrosion may affect multiple parts of a pipe, another pinhole leak may occur somewhere else.

Temporary solutions to pinhole leaks can:

Collapse Under Pressure

Hide More Severe Corrosion

Result In Multiple Repeated Leaks

A professional local plumber will evaluate whether to perform spot repair, replace the entire pipe, or repipe the entire system to provide a secure and long-lasting remedy to the issue.

Pinhole Leak Repair Methods Used By Professional Plumbers

Your plumber will choose the most suitable option depending on where, how big, and why the leak occurred.

Spot Repair

If the corrosion is minimal, the damaged portion of the pipe may be removed and replaced. Spot repair is usually used for isolated leaks.

Pipe Rerouting

When accessing a leak in a hard to access place, rerouting the pipe through a wall or ceiling can be more cost-effective than tearing up a large area of drywall.

Partial Or Complete Repiping

If you’re experiencing continuous pinhole leaks, your plumber may recommend full or partial repiping. Even though this is a much bigger expense, it will give you long term piece of mind and eliminate the possibility of future pinhole leaks.

According to the U.S. Environmental Protection Agency (EPA), household leaks can waste thousands of gallons of water each year if they’re not properly repaired (link suggestion to: EPA WaterSense). Correctly repairing pinhole leaks will both help to conserve water and lower your water utility bills.

How Does A Local Plumber Identify And Locate Pinhole Leaks?

Plumbers who specialize in finding and repairing pinhole leaks use specialized equipment and methods to locate the leaks without damaging walls, ceilings, or floors.

Electronic Leak Detection

Pressure Testing

Visual Inspection of Exposed Piping

Water Quality Analysis

By accurately locating the source of the pinhole leak, your plumber will be able to target and correct the issue effectively, avoiding the necessity of demolishing walls, ceilings, or floors.

Reducing Your Risk For Future Pinhole Leaks

Although some leaks cannot be prevented, you can significantly reduce your risk for future pinhole leaks by doing the following:

Keeping your water pressure safe.

Installing a pressure regulator if necessary.

Scheduling regular plumbing inspections.

Repairing Small Leaks Immediately

Monitoring the quality of your water.

Having your plumbing inspected regularly by a local plumber will enable you to identify the initial signs of corrosion, and potentially avoid future leaks altogether.

When To Contact A Plumber

You Should Contact A Plumber If:

You’ve Had More Than One Pinhole Leak

Leaks Occur In Different Locations

Visible Water Damage Exists

Pipes Are Older Than Average Age

Searching for plumbing services near me will ensure the issue is resolved properly, according to the applicable local plumbing codes.

Even though pinhole leaks may be relatively small, the amount of damage to your home can be significant if the issue goes unresolved. Learning how to diagnose and repair pinhole leaks will empower homeowners to act immediately upon identifying a potential issue. Temporary fixes may solve the immediate issue, but a qualified plumber’s evaluation is the safest course of action to address the issue properly.
