Florida Plumbing System 4‑Point Inspection Guide

The plumbing system is a major component of the Florida 4‑Point inspection. Carriers rely on this section to confirm the home’s supply lines, drain lines, water heater, and fixtures are safe and free of leaks.

How Plumbing Systems Are Evaluated on the 4‑Point Form

Inspectors document the plumbing system using the Florida 4‑Point inspection form. The form requires photos of the water heater, TPR valve, under‑cabinet plumbing, and exposed valves. Underwriting uses this information to determine whether the system is in good working order.

Water Heater Requirements

The inspector records:

• Presence of a temperature pressure relief valve (TPR)

• Any active leaks

• Any prior leaks

• Water heater location

• Water heater age

A missing or improperly installed TPR valve is an automatic underwriting hazard.

Leak Indicators Documented

Inspectors must check for:

• Active leaks

• Prior leaks

• Wet or soft spots

• Mold

• Corrosion

• Grout or caulk failure

Active leaks almost always result in an unsatisfactory plumbing rating.

Fixture & Appliance Condition

The 4‑Point form includes a fixture condition table. Inspectors evaluate whether each item is:

• Satisfactory

• Unsatisfactory

• Not applicable

Fixtures inspected include:

• Dishwasher
• Refrigerator
• Washing machine
• Water heater
• Showers and tubs
• Toilets
• Sinks
• Sump pump
• Main shut‑off valve
• All other visible plumbing

Pipe Types Documented

Inspectors must identify all supply and drain pipe materials present in the home. The form includes:

• Copper
• PEX (with year installed)
• PVC / CPVC
• Galvanized
• Cast iron
• Polybutylene
• ABS
• Other (specified)

The form also documents whether the home has been:

• Completely re‑piped

• Partially re‑piped

• Original piping

Why Plumbing Condition Matters for Insurance

Plumbing failures are one of the most common sources of water damage claims. Carriers rely on the plumbing section of the 4‑Point inspection to determine whether the system is safe and acceptable for underwriting. Homes with active leaks, polybutylene piping, or unsatisfactory fixtures may be declined until repairs are completed.
