Plumbing leaks are a common summer concern for homeowners. Even a small, slow leak can cause significant damage over time, especially if it goes unnoticed. In more serious cases, a burst pipe or broken water line can result in thousands of dollars in repairs and major disruptions to your home. Summer brings a unique set of conditions that can stress plumbing systems, both inside and out. From increased water use to shifting soil and aggressive tree roots, warm weather can expose weaknesses in pipes, fittings, and connections. Let’s look at five common causes of summer plumbing leaks.
1. High Temperatures
During the summer, metal pipes can expand significantly due to high temperatures. This is especially problematic in areas exposed to direct sunlight, such as outdoor pipes or those along exterior walls. For instance, a copper pipe that is constantly exposed to the sun can expand as much as 1/8 inch when the temperature rises significantly.
These pipes then contract in the evening when the temperature drops. This repeated expansion and contraction can weaken joints and fittings, leading to small leaks. Over time, they may worsen, especially where pipes connect at elbows or fittings, causing water to drip onto walls or floors. Faucets are also susceptible to leaks when the constant temperature changes affect their seals and connections. Many homeowners inspect their plumbing regularly, especially after weather extremes, to spot signs of wear before they turn into major leaks.
2. Shifting Soil
Underground pipes are vulnerable to damage during the summer due to shifts in the soil around them. Heavy rains can cause the ground to expand, exerting significant pressure on pipes, which can lead to cracks or even pipe failure. Conversely, long periods of hot, dry weather can cause the soil to shrink, creating gaps or shifting around pipes, which increases the risk of damage.
These issues are more common with older pipes, which tend to be more brittle and prone to breaking. Regular plumbing maintenance and inspections help identify potential problems before they escalate.
3. High Water Use
While winter is often associated with burst pipes caused by freezing, summer brings its own risks for plumbing systems. Warmer weather usually comes with increased water use from activities such as watering lawns, filling swimming pools, washing vehicles, and taking more frequent showers. This extra demand places additional stress on pipes, making it more likely for cracks or leaks to develop.
Using multiple water sources at the same time can increase the strain on your plumbing. For example, running a sprinkler system while also filling a pool can put significant pressure on aging or previously weakened pipes. Fittings and connections that were already slightly loose may start to leak under this stress.
To reduce the risk of plumbing issues during the summer, try to spread out water use throughout the day. For instance, watering your lawn at night can take the pressure off your system if your family tends to shower in the morning. Limiting how much water your household uses at one time can ease the load on your pipes and help prevent leaks from forming.
4. Rust and Corrosion
It’s a common misconception that copper pipes cannot rust or corrode. While copper is more resistant to corrosion than many other metals and doesn’t leach harmful substances into the water, it’s still susceptible to damage over time. Water with a low pH, high oxygen content, or elevated levels of minerals such as chloride can slowly wear away at copper, especially from the inside of the pipe.
As this corrosion progresses, it can weaken pipe walls and eventually cause pinhole leaks. Corroded pipes are also more prone to cracking under pressure. During the summer, the added stress from shifting soil or heavy water use can be enough to cause a weakened pipe to fail.
This is why routine plumbing inspections are important. A licensed plumber can check for early signs of corrosion, such as greenish stains near joints, discolored water, or inconsistencies in your home’s water pressure.
Replacing aging or compromised sections of pipe can prevent much bigger problems down the line. While repiping is a significant project, it’s far less disruptive and costly than dealing with a major leak and the water damage that often follows.
5. Tree Roots
Tree roots invading underground pipes, especially a home’s main sewer line, are a common summer plumbing issue. During hot weather, trees grow more aggressively as their roots search for moisture in the dry soil. Pipes carrying wastewater can become prime targets. Large roots may wrap tightly around a pipe, putting it under pressure until it cracks or collapses. In other cases, a strong root can pierce straight through the pipe wall. These problems are more likely to affect older or corroded pipes, but even newer lines are not immune.
Another frequent issue involves small roots entering sewer lines through loose joints or tiny cracks in the pipe. Once inside, they thrive on a steady supply of water and nutrients. As the roots grow thicker, they can clog the sewer line and, eventually, block the flow altogether. If this continues unchecked, pressure can build inside the pipe, leading to cracks, breaks, or a complete collapse. Leaking sewage from a damaged pipe can cause widespread underground contamination and may require costly remediation methods to clean up.
If your drains are slow or you’ve already had backup issues, tree roots could be the cause. Gurgling sounds, frequent clogs, or foul odors coming from floor drains may also indicate that roots are interfering with your sewer line. In many cases, our plumbers can use non-invasive methods like hydro-jetting to solve the issue. However, a solution like pipe lining or full replacement may be necessary if the pipe is cracked or crushed. Addressing the issue promptly can help prevent further damage and reduce the risk of a complete sewer backup.
Spotting the Signs of Plumbing Leaks
Some plumbing leaks, especially those underground, can be difficult to detect and may go unnoticed for quite some time. That’s why it’s important to review your water bill each month. A sudden, unexplained increase in usage is often one of the first signs that a leak is present.
You can also use your water meter to check for leaks. First, make sure all water fixtures and appliances are turned off. If the dial on your meter continues to move, it likely means there is a significant leak somewhere in your plumbing system, either inside the home or in the underground supply line.
