House plumbing inspection

House Plumbing Inspection

A comprehensive house plumbing inspection identifies current issues, prevents future problems, and ensures your system meets safety and efficiency standards. Whether preparing to buy or sell a home, performing routine maintenance, or troubleshooting recurring issues, a professional inspection gives you a clear picture of your plumbing’s condition.

What a Thorough Inspection Covers

• Water supply lines: Check for leaks, corrosion, improper materials (e.g., galvanized steel), pressure issues, and proper shutoff valve operation.

• Drain, waste, and vent (DWV) system: Inspect drains for blockages, slow drainage, signs of backups, proper venting, and odors indicating sewer gas.

• Fixtures and appliances: Test toilets, faucets, showers, tubs, and water-using appliances (dishwasher, washing machine, water heater) for leaks, proper operation, and correct installation.

• Water heater: Assess age, condition, temperature/pressure relief valve, tank integrity (for tank heaters), pilot/burner operation (for gas), and signs of sediment buildup or inefficiency.

• Sump pump and sewage ejector: Verify operation, float switch function, discharge routing, and backup systems where present.

• Outdoor plumbing: Inspect irrigation connections, hose bibs, exterior spigots for leaks or freeze damage, and visible sewer cleanouts.

• Main sewer line: Check for signs of blockages, root intrusion, bellied pipe sections, or prior repairs—camera inspection recommended when indicated.

• Water quality and pressure: Measure static and dynamic pressure, look for signs of hard water, and recommend testing for contaminants if needed.

• Valves and shutoffs: Confirm accessibility and operation of main shutoff and branch shutoffs; recommend replacements for seized or leaking valves.

• Visible piping materials and routing: Note materials (copper, PEX, CPVC, PVC, cast iron), evaluate proper support and insulation, and identify code or safety concerns.

• Gas plumbing: Inspect gas lines and connections to appliances for leaks and correct venting (when offered by a qualified technician).

Signs an Inspection Is Urgent

• Persistent or hidden leaks, especially inside walls or ceilings

• Sewage odors or repeated drain backups

• Rapidly increasing water bills

• Discolored water or rust flakes

• Water heater issues (no hot water, rumbling noises, visible corrosion)

• Low or fluctuating water pressure throughout the house

Inspection Methods and Tools

• Visual inspection of exposed piping, fixtures, and appliances

• Pressure testing and meter readings

• Dye tests for toilet leaks

• Thermal imaging to locate hidden leaks or insulation gaps

• Video camera sewer inspection for main lines and deep clogs

• Water sampling for quality testing

• Smoke or gas leak detection for gas lines

Typical Inspection Deliverables

• Written report summarizing findings, prioritized by safety and urgency

• Photos or video clips of problem areas (e.g., camera sewer footage)

• Cost estimates for recommended repairs or replacements

• Maintenance recommendations and timelines

• Optional follow-up inspection after repairs

DIY Prep for an Inspector

• Clear access to crawlspaces, basements, and utility rooms

• Provide access to the main water shutoff and water heater

• Note any past plumbing issues, repairs, or warranties

• Make a list of problem areas (slow drains, noises, odors) and when they started

When to Hire a Licensed Plumber

• Evidence of gas leaks, sewage backups, structural water damage, or major sewer line problems

• Water heater replacement or complicated appliance connections

• Remodeling or adding new plumbing fixtures

• When inspection reveals corroded supply mains or systemic pipe failures

Benefits of Regular Inspections

• Early detection of leaks and corrosion saves on repair costs and reduces water damage risk

• Improved water efficiency and lower utility bills

• Prolonged life for appliances and piping

• Safer home environment with reduced risk of mold and sewer gas exposure

• Documentation that supports home sales and insurance claims
