Top Plumbing Problems in Older Pearland Homes (And How to Spot Them)

The Plumbing Reality of Older Pearland Homes

From the neighborhoods around East Broadway to the historic homes near Old Alvin Road, Pearland has plenty of homes built before modern plumbing codes and materials became standard. While these homes often have charm and character, their plumbing systems may show signs of age.

If your home—or your client’s home—is 20 years old or more, here’s what to watch for.

Common Plumbing Issues in Older Pearland Homes

1. Galvanized Steel Pipes

Homes built before the 1980s often used galvanized steel pipes. Over time, these corrode from the inside out, reducing water flow and increasing the risk of leaks or pipe bursts.

Signs to look for:

• Brown or rust-colored water
• Noticeable drop in water pressure
• Pipes that rattle or clang when turning water on/off

2. Slab Leaks

Many Pearland homes are built on concrete slabs. Over time, soil movement and moisture changes can cause tiny shifts that lead to cracks in the foundation—and leaks in the pipes beneath it.

Warning signs include:

• Warm or damp spots on the floor
• A sudden spike in your water bill
• Mold or mildew smells with no visible source

3. Outdated Drain Lines

Older cast iron drain pipes deteriorate over time, leading to clogs, backups, or slow drains. Even early PVC used in the '80s and '90s may become brittle and crack with age.

You may notice:

• Frequent backups in tubs or toilets
• Gurgling or bubbling sounds from drains
• Sewer gas odors coming from sinks or floors

4. Corroded Shutoff Valves and Fixtures

Old valves can seize up or leak, especially under sinks and behind toilets. Fixtures like faucets and showerheads also wear out and become prone to leaks.

Watch for:

• Drips around valve handles
• Hard-to-turn or stuck knobs
• Leaks that return even after tightening connections

Why These Problems Are Common in Pearland

The combination of humid weather, clay-rich soil, and older building practices makes plumbing issues more likely as homes age. Pearland’s natural environment causes more shifting, condensation, and pipe expansion than many other areas in Texas.

What You Can Do

For Homeowners:

• Schedule a plumbing inspection if your home is over 20 years old
• Consider upgrading to PEX or copper if your pipes are original
• Watch your water bill and listen for sounds in your plumbing
• Don’t ignore small signs—they often lead to bigger repairs

For Realtors & Buyers:

• Always ask when the home was last repiped or inspected
• Recommend a sewer camera inspection during the option period
• Look for signs of previous water damage or repairs behind walls
