Most homeowners never have their plumbing professionally inspected until something breaks. That's understandable — plumbing that's working is invisible, and nobody pays to inspect invisible things. But a proactive plumbing inspection catches small problems before they become expensive ones, and for older homes, an inspection every few years is genuinely good value.
What a Plumbing Inspection Covers
A thorough residential plumbing inspection typically includes:
- Visual check of exposed supply lines — copper, PEX, or galvanized — for corrosion, leaks, or pinhole spots
- Water heater age, condition, venting, and T&P valve check
- Main shutoff valve operation (does it actually close?)
- Sump pump operation test (if present)
- Toilet flange and wax ring condition
- Sink, tub, and shower drain flow and condition
- Outdoor hose bibs and frost-free sillcocks
- Visible waste and vent lines — especially cast iron, which corrodes from the inside
- Gas line visual check for obvious leaks (soap test if concerned)
- Water pressure reading and any obvious water quality concerns
A more thorough inspection can include a video camera scope of the main sewer line — which is the only way to actually see what's happening in the buried portion of your plumbing.
How Often to Schedule One
- Home under 10 years old: inspection every 3–5 years is usually sufficient.
- Home 10–40 years old: every 2–3 years, especially if you haven't had major plumbing updates.
- Home 40+ years old: every 1–2 years. Galvanized supply lines, cast iron drains, and clay sewer mains all have predictable failure modes, and catching them early matters.
- Buying a home: always. A pre-purchase plumbing inspection (separate from the general home inspection) is one of the highest-ROI expenses in a real estate transaction.
What It Typically Costs
A basic residential plumbing inspection is usually a flat rate — often comparable to a service call. Adding a sewer main camera scope increases the cost but can be negotiated into the price if work is recommended as a result.
When to Skip the Inspection
If your plumbing is working fine, your home is under 10 years old, and you haven't seen any warning signs, a formal inspection is optional — a simple annual self-walkthrough (checking under sinks for leaks, testing the sump pump, looking at the water heater) catches most issues.
