Quick Answer

Plumbing inspection covers supply, drain, water heater, fixtures, and visible piping. Plumbing failures are some of the most expensive and disruptive surprise repairs.

What we check on every plumbing inspection

  • Water main shutoff location and operation
  • Supply line material (galvanized, copper, PEX, polybutylene)
  • Drain line material and visible connections
  • Water heater age, capacity, T&P valve, expansion tank, vent
  • Fixture operation, drain speed, leaks under sinks
  • Water pressure and any noticeable pressure issues
  • Sump pump presence and operation

Common defects we find

  • Galvanized supply piping with reduced flow and rust
  • Polybutylene supply piping (1980s) — known failure-prone material
  • Original cast-iron drain stacks at end of service life
  • Water heaters past 12-year typical service life
  • Missing or improperly sized expansion tank
  • Failed sump pumps or no backup

Southern Minnesota considerations

Pre-1960 southern-MN homes commonly still have original galvanized supply lines. 1980s subdivisions often have polybutylene — a known failure-prone material that should be flagged for any buyer.

Common questions

How do you check for hidden leaks?

Visual inspection plus FLIR thermal imaging (premium add-on) finds most hidden moisture issues. We check under sinks, around water heaters, behind toilets, and look for ceiling stains indicating upstairs leaks.

Will you tell me if I have polybutylene?

Yes. Polybutylene is identified by its gray-brown color and visible "PB" markings. We always document polybutylene because it has known failure patterns and should be replaced.
