Common Plumbing Problems in Older Florida Homes

Northwest Florida is home to many charming older properties, from historic Destin cottages to mid-century Fort Walton Beach homes. While these homes have character, they often come with plumbing systems that need attention. Here's what to watch for.

Galvanized Steel Pipes

Homes built before the 1960s often have galvanized steel pipes. Over time, these pipes corrode from the inside, leading to:

• Reduced water pressure
• Rusty or discolored water
• Frequent leaks
• Metallic taste in water

Polybutylene Pipes

Many Florida homes built between 1978 and 1995 used polybutylene (PB) pipes, identifiable by their gray color. These pipes are prone to sudden failure and are no longer approved for use. Insurance companies may refuse coverage for homes with PB plumbing.

Outdated Water Heaters

Older water heaters lose efficiency over time and can become safety hazards. Signs you need a replacement include:

• Unit is over 10-12 years old
• Rust around the base or on fittings
• Rumbling or popping noises
• Inconsistent water temperatures
• Higher energy bills

Cast Iron Drain Lines

Cast iron sewer lines were standard in homes built before 1970. While durable, they eventually rust and develop cracks, leading to slow drains, sewage odors, and even foundation damage from leaking waste.

Bellied Sewer Lines

Florida's shifting sandy soil can cause sewer lines to develop low spots or "bellies" where waste collects. This leads to recurring clogs and can eventually cause the pipe to collapse.

Outdated Fixtures and Valves

Older shut-off valves, faucets, and toilet components can fail without warning. It's wise to replace these components proactively rather than waiting for an emergency.

Tree Root Intrusion

Mature trees on older properties may have roots that have grown into sewer lines. Signs include recurring drain clogs, gurgling toilets, and patches of extra-green grass in the yard.

What You Can Do

If you own an older Florida home, we recommend:

• Schedule a professional plumbing inspection
• Have your sewer line camera-inspected
• Budget for pipe replacement if needed
• Update shut-off valves throughout the home
• Consider whole-house water filtration
