Aging homes offer endless beauty and character. However, many of them are often plagued by compromised plumbing systems. If you live in an older property, it’s important to recognize the signs of potential problems. The guide below discusses common plumbing issues in older homes and how to keep an eye out for them.

How Long Do Different Plumbing Materials Last?

From the 1930s to the 1980s, galvanized steel pipes were commonly used in home construction. The heavy-duty material was coated with zinc, which runs the risk of losing its integrity over time. As the covering fades away, the pipe may be vulnerable to corroding. As a result, rust deposits could accumulate in the pipe and affect water pressure and quality. The average galvanized pipe may last for anywhere from 80 to 100 years before it starts to fail.

Lead-based pipes are often found in homes built during the early 1900s. While they may last for up to a century, they must be replaced promptly since lead is highly toxic and may seep into the water supply. The same applies to brass, which has a life expectancy of between 40 and 100 years. 

Finally, polybutylene (PB) piping was often used in homes constructed from the late ’70s to the mid-’90s. They’re prone to bursting without warning, causing everything from minor leaks to major flooding.

What Are Signs Your Plumbing Is Past Its Lifespan?

Investigate your home’s plumbing at least once a year if you live in an old property. Signs of potential corrosion include flaking, discoloration, and staining. Since aging pipes are also vulnerable to leaks, check for cracks. Even if you don’t see anything, inspect the surface beneath the pipes for moisture or signs of rot or mold—both are indications of a possible leak. Warped floors and ceiling stains also indicate underlying leaks near those areas.

Another common issue that may befall an aging system is reduced water pressure. When limited to a single drain, it’s likely due to a clog. If it affects the entire house, then it could be due to corroded deposits built up in the aging pipes.
