Plumbing Inspection Issues Guide

Plumbing issues range from $50 fixes to $10,000+ re-pipes. Here's how to evaluate what your inspector found.

Common Plumbing Findings

  • Slow drains: May indicate clogs or bigger issues. Cleaning: $100–$300. Sewer scope recommended if multiple drains affected
  • Polybutylene pipes (1978–1995): Known failure-prone material. Full re-pipe: $4,000–$10,000. May affect insurability
  • Galvanized steel pipes: Pre-1960 homes. Corrosion reduces flow over time. Eventually need replacement: $4,000–$10,000
  • Active leaks: Under sinks, at connections, in basement. Fix: $150–$500 per leak
  • Low water pressure: Could indicate corroded pipes, municipal supply, or PRV issue. Diagnosis: $100–$300
  • Sewer line concerns: Get a sewer scope ($200–$400). Replacement if needed: $3,000–$10,000

The Sewer Scope Question

If your inspection raises any plumbing or drainage concerns, get a sewer scope. It costs $200–$400 and can reveal $5,000–$15,000 problems (root intrusion, bellied pipes, collapsed sections). This is one of the highest-ROI diagnostic tests a buyer can order.

Negotiation Approach

Known failure-prone pipe materials (polybutylene, orangeburg sewer) = strong negotiation items. Active leaks = seller should fix or credit. Aging but functional pipes = budget for future, don't negotiate hard. Low pressure or slow drains = diagnose before negotiating.

Cost range

Plumbing repair range: $150–$15,000
