Water damage is one of the most expensive issues property managers deal with—and many plumbing problems start small. Knowing what to look for can prevent a minor drip from becoming a major flood.

In homes built before 1990, corrosion in copper pipes is a growing concern. Look for green-blue stains around fittings or a drop in water pressure. In bathrooms, check under sinks for slow drips, soft cabinet floors, or mold.

Toilets that run constantly or gurgle during flushing could indicate partial clogs or venting issues. Listen to tenant complaints about slow drainage in kitchens, showers, or laundry areas.

Inspect water heaters annually. In rental properties, these often go untouched for years. Rust at the base or fluctuating hot water is a red flag.

Pro Tip: Add leak sensors under major appliances and water heaters. These affordable devices can alert you before damage spreads.

Preventive plumbing inspections—especially in older properties—are a smart way to protect your investment and keep tenants happy.
