Whether you are buying a home or planning a remodel, a plumbing inspection helps you avoid costly surprises. A strong inspection process is not just about finding leaks. It is about confirming safety, code alignment, and realistic project scope before work begins.
Homebuyer Plumbing Inspection Checklist
Use this checklist before closing:
- Confirm water pressure and fixture performance
- Check water heater condition, venting, and safety setup
- Inspect visible supply and drain lines for corrosion or active leaks
- Test all toilets, shutoff valves, and major fixtures
- Evaluate signs of hidden moisture or prior leak damage
- Consider sewer camera inspection for older homes
Remodel Plumbing Checklist
Before opening walls or ordering materials:
- Confirm which plumbing changes need permits
- Validate fixture rough-in locations and drain slopes
- Check pipe material condition (copper, cast iron, PEX, PVC)
- Identify any code corrections needed before finish work
- Build contingency budget for hidden corrections
When an Inspection Fails
A failed inspection is usually fixable, but speed matters. The best sequence is:
- Get a clear correction list.
- Prioritize safety and code issues first.
- Complete corrective plumbing scope.
- Re-inspect with documentation ready.
Typical Bay Area Planning Ranges
