What’s Included in a Whole-Home Plumbing Inspection?
Homeownership comes with regular upkeep, and few systems are as essential (or as easily overlooked) as your plumbing. A Whole-Home Plumbing Check ensures your pipes, fixtures, and appliances are all functioning efficiently and safely. Whether you’re preparing to buy a home, selling one, or just trying to stay ahead of costly repairs, a thorough Plumbing System Evaluation can save you serious time and money.
In this guide, we’ll explore what’s included in a Plumbing Inspection Checklist, why these evaluations matter, and when to schedule yours.
Why Plumbing Inspections Are Critical
Most plumbing systems are tucked behind walls and beneath floors, which means small issues can grow unnoticed. A Whole-Home Plumbing Check gives you peace of mind and early warning for issues like:
Water damage from hidden leaks
Unsafe water pressure
Pipe corrosion or clogs
Faulty water heaters
Sewer line concerns
Annual plumbing inspections are a smart preventative measure. And when conducted by licensed professionals like Eastside Repipe & Plumbing, they become a powerful tool for long-term home care.
What Does a Whole-Home Plumbing Inspection Include?
A full Plumbing System Evaluation is far more than just checking for leaks. Here’s a breakdown of the most important elements on a standard Plumbing Inspection Checklist.
1. Visual Pipe Inspection
The plumber will examine exposed pipes for:
Corrosion or rust
Leaks or moisture buildup
Signs of past repairs or patch jobs
Material type (e.g., galvanized steel, copper, PVC)
This part of the Whole-Home Plumbing Check reveals a lot about the health and longevity of your system.
2. Water Pressure Testing
Too little pressure? Your showers may be frustrating. Too much? You risk pipe bursts. Professionals test the home’s water pressure to ensure it falls between 40–80 PSI.
Improper pressure can indicate:
Hidden leaks
Sediment buildup
Regulator failure
Your Plumbing System Evaluation will uncover any issues and recommend fixes like a new pressure regulator or pipe cleaning.
3. Drainage and Flow Evaluation
Slow-draining sinks or tubs could signal:
Partial clogs
Vent pipe blockages
Broken or misaligned pipes
This part of the Plumbing Inspection Checklist ensures every drain flows freely without gurgling, bubbling, or backups.
4. Faucet and Fixture Inspection
Each faucet, showerhead, and toilet is checked for:
Leaks and drips
Proper water flow
Secure mounting and seals
Rust or wear
Any leaks here can waste hundreds of gallons a month—and quietly inflate your water bill. Eastside Repipe’s plumbers will identify both minor and major fixture concerns.
5. Water Heater Assessment
Your water heater is one of the most important—and expensive—components of your plumbing system. During your Whole-Home Plumbing Check, technicians will:
Check for leaks or corrosion
Inspect the anode rod
Verify water temperature (ideally between 120–130°F)
Ensure the pressure relief valve is functional
Examine sediment buildup
This part of the Plumbing System Evaluation can help extend your heater’s life and improve efficiency.
6. Sewer Line and Drainage Inspection
Though not always included in a basic inspection, many homeowners opt for a camera-assisted Plumbing System Evaluation of the sewer line.
This identifies:
Tree root intrusions
Pipe misalignment
Major clogs
Cracks or leaks underground
Eastside Repipe & Plumbing’s General Services include advanced camera inspections for accurate diagnostics with minimal disruption.
7. Shutoff Valve and Emergency Access Review
Knowing where your main water shutoff is—and making sure it works—could save your home from major flood damage. Your plumber will:
Locate and label the main shutoff
Test valves near sinks, toilets, and appliances
Recommend replacements if old or stuck
This step in your Plumbing Inspection Checklist prepares you to act fast in case of emergencies.
8. Appliance Connection Checks
Appliances like dishwashers, washing machines, and refrigerators are all connected to your plumbing system. During your Whole-Home Plumbing Check, a technician will inspect:
Supply lines
Drain hoses
Valve conditions
Leak risks near floors or walls
Even small appliance leaks can result in mold, warped flooring, and structural damage if left unaddressed.
When Should You Schedule a Plumbing System Evaluation?
Here are the most common times homeowners should consider a full Plumbing Inspection Checklist:
Annually, as a routine maintenance step
Before buying a home, to uncover hidden issues
Before selling a home, to avoid last-minute surprises
After a major storm or earthquake, check for underground damage
After a water bill spike, to investigate hidden leaks

Benefits of a Professional Inspection
Attempting a DIY inspection may catch obvious problems, but it won’t uncover the full picture. Here’s why hiring a licensed plumber for your Plumbing System Evaluation is worth it:
Advanced tools: Thermal imaging, pressure gauges, and pipe cameras
Expert insight: Professionals know what signs to look for—and where
Comprehensive reporting: Receive a summary of findings and recommended repairs
Early issue detection: Avoid major repairs or water damage down the line
A professional inspection offers peace of mind—and pays off in long-term savings.
How to Prepare for a Whole-Home Plumbing Check
Make the most of your appointment by preparing your space:
Clear access to sinks, appliances, water heater, and shutoffs
Make a list of concerns or recent symptoms (low pressure, drips, etc.)
Gather documents if available—previous repair records or warranties
Be available to answer questions and review the findings
Eastside Repipe’s team makes the process smooth and respectful of your time and home.
