New Home Plumbing Inspection Checklist: For New Construction and Older Homes

Plumbing Checklist for Buying New or Older Homes
Buying a home in Jacksonville — whether it’s shiny new construction or a charming older property — is exciting. But hidden plumbing issues can turn your dream home into a headache. From builder oversights in new builds to aging pipes in historic homes, a careful plumbing inspection is essential before closing.
This combined New Home Plumbing Inspection Checklist gives you two tailored checklists:
-
- One for brand-new construction
-
- One for older homes
Use the version that fits your situation (or both if you’re touring a mix of homes) to spot problems early, negotiate repairs, and move in with confidence.
Why a Plumbing Inspection Matters
-
- Prevent costly surprises: Hidden leaks or flaws can cost thousands to repair after move-in.
-
- Strengthen negotiations: Inspection findings can lead to credits or seller repairs.
-
- Ensure safety and quality: Verify everything is up to code and functioning properly.
-
- Peace of mind: Move into your new home knowing the plumbing is sound.
Plumbing Inspection Checklist for New Construction
Even brand-new homes can have plumbing mistakes — loose fixtures, missing shut-offs, or improperly installed connections. Use this checklist during your builder walkthrough:
Checklist for New Construction
-
- Turn on every faucet to check water pressure and hot/cold balance.
-
- Inspect toilets for proper flushing and secure installation.
-
- Confirm all shut-off valves are labeled and accessible.
-
- Test the water heater for function and verify energy source (gas or electric).
-
- Check dishwasher, laundry, and refrigerator connections for leaks.
-
- Ensure outdoor hose bibbs work and are frost-proof if needed.
Pro Tips for New Builds
-
- Request plumbing schematics from the builder for future repairs.
-
- Verify installation of water softener loops if included in the build.
-
- Consider upgrading builder-grade fixtures for long-term durability.
Plumbing Inspection Checklist for Older Homes
Older homes bring character — and often outdated plumbing. Use this checklist to uncover hidden issues:
Checklist for Older Homes
-
- Look under sinks for water stains, leaks, or mold.
-
- Check toilet bases for movement or leaks.
-
- Inspect the water heater’s age (10+ years likely needs replacement).
-
- Test water pressure at multiple fixtures.
-
- Look for rusty or discolored water (sign of aging pipes).
-
- Inspect crawlspaces or basements for corrosion or leaks.
Pro Tips for Older Homes
-
- Budget for possible cast iron sewer line replacement in historic neighborhoods.
-
- Ask sellers for repair history and warranties on recent upgrades.
-
- Schedule a sewer camera inspection for peace of mind on older properties.
