Key takeaways
- Identify the pipe materials: galvanized, polybutylene, copper, PEX.
- Camera the sewer line before closing.
- Check the water heater age and pressure.
- Ask for repair and permit history.
Look at the pipes
Check the water heater area, under sinks and the crawl space or basement for pipe materials. Gray flexible pipe may be polybutylene, dull steel may be galvanized and green-crusted copper may be failing. Look for stains, patched pipes and signs of past leaks.
Ask the seller what has been repaired or replaced and for any receipts.
Test the system
Run every faucet, shower and toilet. Check pressure with a gauge at an outdoor faucet, look for slow drains and listen for banging. Check the age of the water heater and its venting, and ask when the main shutoff was last tested.
Many problems only show up when several fixtures are running at once.
Scope the sewer
A camera inspection of the main sewer line is one of the best protections for a buyer, especially with clay, cast iron or Orangeburg pipe and large trees nearby. It costs far less than a surprise replacement.
Use the findings to negotiate or to plan repairs. A written plumbing inspection with photos gives you a clear list of what is urgent, what can wait and what to budget for.

Quick answers
Should I get a plumbing inspection and a general home inspection?
A general inspection checks visible plumbing. A plumbing inspection goes deeper with pressure tests and a camera, so many buyers of older homes do both.
Can I ask the seller to fix plumbing problems?
Yes. You can ask for repairs, a credit or a price change. A written report from a plumber supports the request.
