Protect Your Home From Hidden Leaks, Mold, and Costly Plumbing Problems
Most plumbing issues begin long before a homeowner ever notices them. A tiny drip under a sink, an aging shutoff valve, a worn flex line, or a slow drain can quietly build into mold, dry rot, or flooding.
A Whole Home Plumbing Evaluation gives homeowners a clear picture of their plumbing system’s condition. It identifies early warning signs and helps prevent expensive repairs.
McCray & Sons Home Services provides detailed, professional evaluations that focus on long-term home protection, safety, and prevention.
What Is a Whole Home Plumbing Evaluation?
A Whole Home Plumbing Evaluation is a top-to-bottom visual review of all accessible plumbing components in your home. Instead of waiting for emergencies, this evaluation helps homeowners identify early warning signs and understand the health of their plumbing system.
This evaluation is a visual review of accessible plumbing components and does not include destructive testing, leak detection, pressure testing, or system certification, including gas systems.
We review your water supply, drainage systems, water heater, and fixture performance, and we check for any signs of leaks, corrosion, or failures.
What Our Plumbing Evaluation Includes
1. Water Supply System
We review the condition of all major water supply components, including:
Shutoff valves and angle stops
Flexible supply lines to sinks, toilets, water heaters, dishwashers, and washing machines
Visible copper, PEX, PVC, or galvanized piping
General water pressure levels
Evidence of corrosion, sweating, or small leaks
These checks help prevent sudden floods caused by aging or failing valves and hoses.
2. Drains and Sewer System
Our evaluation includes:
Testing drain flow in sinks, tubs, and showers
Inspecting P-traps and under-sink drainage
Checking for sewer odors or venting issues
Identifying slow drains that may indicate early blockages
If deeper problems are suspected, we can recommend a sewer camera inspection.
3. Water Heater Evaluation
Your water heater is one of the most important and most vulnerable systems in your home. This evaluation includes a visual review of the water heater and its associated water and gas connections, where applicable.
We check for:
Age and expected lifespan
Signs of leaks, rust, or corrosion
Earthquake strapping consistent with current California requirements
Expansion tank condition
Sediment buildup indicators
Visible venting condition and installation
Many water heaters fail without obvious warning. Early detection helps avoid major water damage.
4. Bathroom Plumbing Review
Bathrooms are one of the most common sources of hidden leaks. We evaluate:
Toilet stability and leaks at the base
Shower and tub valve operation
Caulking and grout condition
Under-sink supply lines and visible drainage condition
Even a slow toilet leak can cause subfloor damage if unnoticed.
5. Kitchen Plumbing Review
A quick look under the kitchen sink often reveals issues homeowners were unaware of.
We assess:
Garbage disposal function and condition
Visible supply and drain lines under the sink
Cabinet floors for moisture damage
Dishwasher supply and drain connections
Faucet and sprayer performance
6. Laundry and Exterior Plumbing
Additional areas we evaluate include:
Washing machine hoses and drainage
Exterior hose bibs
Vacuum breakers
Signs of moisture in crawlspaces if accessible
Washing machine hoses are one of the top causes of sudden home flooding, especially older rubber hoses.
Common Issues Found During Plumbing Evaluations
Our evaluations often uncover:
Expired or deteriorating angle stops
Bulging or corroded supply hoses
Slow drains and indicators of potential sewer concerns
Water heaters nearing end-of-life
Mold or mildew under sinks
Toilets leaking slowly into flooring
Galvanized pipe corrosion
Previous DIY repairs showing signs of concern
Identifying these issues early saves homeowners thousands of dollars and prevents major disruptions.
Why Plumbing Evaluations Save Money
A Whole Home Plumbing Evaluation helps prevent:
Mold and mildew
Dry rot and structural damage
Flooring and cabinet damage
Flooding from burst supply lines
Large emergency plumbing bills
Sewer backups
Water heater failures
Routine evaluations are one of the easiest ways to protect your home.
How Often Should You Schedule a Plumbing Evaluation?
Once a year for most homes
Twice a year for homes older than 30 years
Before buying or selling a home
After major plumbing repairs
**Frequency may vary based on home age, plumbing materials, and usage
Regular evaluations keep your plumbing system healthy and reduce the risk of emergency repairs.
