Plumbing Inspection Cost: Whole-House & Camera Inspections

01What a good inspection covers

A thorough plumbing inspection is a system-wide walk, not a glance under the sink. The plumber checks water pressure and the pressure regulator, tests every fixture for flow and drainage, looks under sinks and around toilets for leaks and corrosion, examines the water heater age and condition, and confirms the main shutoff and fixture valves actually work.

• ·Water pressure reading and PRV check (40 – 80 psi is the normal band)
• ·Every fixture run for flow, drainage and leaks
• ·Water heater age, venting, relief valve and signs of corrosion
• ·Visible supply pipe material: copper, PEX, or red-flag galvanized and polybutylene
• ·Main and fixture shutoff valves tested, not just eyeballed
• ·Drain and vent function, including any shared wet vent serving more than one fixture, with a camera scope of the main if added

02Why the sewer camera is the add-on that pays

A visual inspection sees the parts above ground. The main sewer line, the single pipe carrying everything out to the street, is buried and invisible until something fails. A sewer camera inspection sends a scope down the line to show roots, cracks, bellies and the pipe material on screen.

On an older home, or one with mature trees near the line, this $230 – $700 add-on is the highest-value part of the whole inspection. Finding root intrusion or a collapsed clay line before closing can save you from a sewer line replacement that runs into five figures. It turns an invisible unknown into a documented, negotiable fact.

03The pre-purchase context

A standard home inspector glances at the plumbing but rarely tests it system-wide or scopes the sewer. On any home more than twenty or thirty years old, a dedicated plumbing inspection by a licensed plumber is worth ordering separately during your option period. The cost is trivial against the price of the house and the systems involved.

The timing matters: schedule it while you still have the right to negotiate or walk. A few hundred dollars spent before closing is leverage; the same problem found after closing is your bill alone. This is the rare inspection that frequently pays for itself many times over on a single finding.

04Red flags that become negotiation items

The value of the report is in what it lets you ask for. Each documented defect is either a price reduction, a seller repair, or a credit at closing, and a written inspection gives those requests teeth.

• ·Galvanized or polybutylene supply lines flagged for a future whole-house repipe
• ·A water heater at or past 10 years, due for replacement
• ·Roots or a cracked main line on the camera scope
• ·A failed or missing pressure regulator, or pressure outside 40 – 80 psi
• ·Active leaks, corroded shutoff valves, or a slab leak under investigation

05How to get full value from the report

Ask for photos and the camera footage, not just a checklist. A clear image of a root mass in the main line is worth more at the negotiating table than a line item, and it tells the next contractor exactly what they are walking into.

Have the plumber separate the findings into safety or active-damage issues, near-term replacements, and minor notes. That triage tells you what to push hard on in negotiation, what to budget for in the next year or two, and what to simply file away. A good report is a roadmap for the home, not just a pass-or-fail grade.
