Water Damage Starts Small but Grows Fast
Why Plumbing Issues Matter
Water damage is expensive and sneaky. A small leak can cause thousands in damage before you even notice. Plus, plumbing repairs often require opening walls and floors, adding to costs.

Plumbing Problems: Act Quickly
Small leaks become big disasters
Major Plumbing Red Flags
1. Polybutylene (PB) Pipes
What to look for: Gray plastic pipes, often stamped “PB2110” (installed 1978-1995)
Why it matters: Known to fail catastrophically without warning. Many insurance companies won’t cover homes with PB pipes.
Cost range: $4,000-$15,000 to replace entire system
My advice: This is a deal-breaker for most buyers. Require replacement or walk away.
2. Galvanized Steel Pipes
What to look for: Dull gray pipes (common in homes built before 1960)
Why it matters: Corrode from inside out, reducing water pressure and quality. Typically fail after 40-50 years.
Cost range: $4,000-$12,000 to replace
3. Old Water Heater
What to look for: Water heater 10+ years old, rust, corrosion, or leaking
Why it matters: Average lifespan is 8-12 years. Failure causes flooding.
Cost range: $800-$2,500 for standard tank replacement; $2,000-$4,500 for tankless
4. Active Leaks or Water Damage
What to look for: Stains on ceilings/walls, soft spots, musty odors, visible drips
Why it matters: Often indicates larger hidden problems; can cause mold
Cost range: $200-$1,000 for leak repair; $500-$5,000+ for water damage repair
5. Low Water Pressure
What to look for: Weak flow from multiple fixtures
Why it matters: Could indicate corroded pipes, leaks, or municipal supply issues
Cost range: Varies greatly depending on cause
6. Sewer Line Issues
What to look for: Multiple slow drains, gurgling sounds, sewage odors, lush patches in yard
Why it matters: Tree root intrusion or collapsed pipes cause backups and expensive repairs
Cost range: $3,000-$25,000+ depending on severity
My advice: For older homes, get a sewer scope inspection ($200-$400)
💡 Your Action Plan:
- Stay calm and take detailed notes
- Get 2-3 repair estimates from foundation specialists
- Negotiate: Request repairs, price reduction, or closing credit
- For severe issues, consider walking away
