Maintaining your home’s plumbing system is essential for preventing costly water damage, improving efficiency, and ensuring long-term peace of mind. At Home Alliance, we believe that every homeowner should understand how to perform a comprehensive home plumbing inspection. With the right tools and a methodical approach, you can detect issues early and avoid expensive repairs later.
Below, we share a step-by-step guide on how to inspect your home plumbing system like a professional plumber.
Start with a General Overview of Your Plumbing System
Before diving into specific fixtures, take time to understand your home’s plumbing layout. Know where your main water shut-off valve is located - typically near the water meter or where the main line enters the house. Test this valve to ensure it turns smoothly and fully shuts off the water supply.
Also, identify branch shut-off valves for individual fixtures or appliances, such as sinks, toilets, and washing machines. This knowledge will save valuable time in case of a leak or plumbing emergency.
Inspect for Leaks Around Fixtures and Pipes
Even small leaks can waste hundreds of gallons of water each year and cause mold or structural damage. Start by visually inspecting:
- Under sinks – Check for dampness, water stains, or dripping connections.
- Around toilets and tubs – Look for signs of moisture or discoloration on the floor.
- Basement and crawl spaces – Inspect exposed pipes for corrosion, condensation, or water puddles.
- Ceilings and walls – Watch for bubbling paint or brown spots that may indicate hidden leaks.
Use a dry cloth or paper towel to detect subtle moisture and a flashlight to inspect dark corners.
Check Water Pressure Throughout Your Home
Proper water pressure is vital for both comfort and appliance longevity. Too low, and your showers become frustrating; too high, and pipes or fixtures may burst over time.
Attach a water pressure gauge to an outdoor hose bib or laundry faucet. Ideal household pressure should range between 40 and 60 PSI (pounds per square inch).
If readings are above 80 PSI, consider installing a pressure-reducing valve (PRV) to protect your plumbing system. If pressure is low, check for clogged aerators, mineral buildup, or a malfunctioning pressure regulator.
Examine Faucets, Showerheads, and Aerators
Turn on every faucet in your home, both hot and cold. Observe the water flow and listen for unusual noises such as rattling or hammering. Inconsistent water flow may indicate clogged aerators or mineral buildup.
To clean them:
- Unscrew the aerator or showerhead.
- Soak in vinegar for 15–30 minutes to dissolve limescale.
- Rinse thoroughly and reattach.
This simple maintenance task not only improves water pressure but also enhances overall water efficiency. For tips on selecting water-efficient fixtures and conserving water, check out the EPA’s WaterSense program.
Inspect Toilets for Leaks and Proper Operation
Toilets are one of the most common sources of hidden leaks. Start by removing the tank lid and examining the internal components:
- Flapper valve – Ensure it seals properly and isn’t warped or cracked.
- Fill valve – Confirm it shuts off when the tank is full.
- Flush handle – Test for smooth operation without sticking.
To detect silent leaks, add a few drops of food coloring to the tank. Wait 10–15 minutes without flushing. If color appears in the bowl, the flapper is leaking and needs replacement.
Evaluate Drains and Check for Clogs
Slow drains are a telltale sign of developing blockages. Run water down every sink, tub, and shower drain, watching for gurgling noises or sluggish drainage.
To maintain free-flowing drains:
- Pour boiling water weekly to break down grease and soap buildup.
- Avoid using harsh chemical cleaners; opt for enzyme-based drain cleaners instead.
- Install drain strainers to catch hair and debris.
If multiple drains are slow simultaneously, the problem could be in your main sewer line. This is why you should get a sewer inspection today to prevent major backups and costly repairs.
Inspect Exposed Pipes for Corrosion or Damage
Take time to examine visible pipes in basements, under sinks, and utility areas. Look for rust, white mineral deposits, or green discoloration, all of which indicate corrosion or slow leaks.
Pay close attention to pipe joints and fittings, as these are common leak points. For older homes with galvanized steel pipes, corrosion can severely restrict water flow and may necessitate repiping.
Additionally, check for vibration or rattling sounds when water flows - these can be urgent signs that you need a main pipe replacement and should be addressed immediately.
Test Your Water Heater’s Performance
Your water heater plays a critical role in daily comfort. Inspect it annually to ensure it’s functioning safely and efficiently.
- Check for leaks around the base.
- Listen for rumbling noises, which may indicate sediment buildup.
- Inspect the temperature setting - ideally around 120°F to prevent scalding and reduce energy costs.
- Drain and flush the tank at least once a year to remove sediment.
For tankless water heaters, follow manufacturer guidelines for descaling to maintain peak performance and enjoy the great benefits of tankless water heaters for your home.
Examine Outdoor Plumbing and Irrigation Systems
Outdoor plumbing and irrigation systems are often overlooked but play a crucial role in maintaining a functional home. Regularly inspect hose bibs, sprinkler heads, and irrigation lines for leaks or visible damage, especially after cold weather. Turn on outdoor faucets to ensure steady water flow, as low pressure or pooling water may indicate hidden or buried leaks.
To protect your plumbing during winter, follow some simple ways to prevent pipe freezing and avoid costly damage. Using insulated covers on exposed pipes helps prevent bursting, saving both money and stress while ensuring your outdoor plumbing stays in top condition.
Test the Sump Pump (if applicable)
If your home is equipped with a sump pump, regular testing is essential to prevent basement flooding during heavy rain. Pour several gallons of water into the sump pit; the pump should activate immediately and efficiently remove the water. Watch its performance carefully, ensuring it operates smoothly without unusual noises or delays.
Also, inspect the discharge line to make sure it channels water away from the foundation. Clean the pump inlet screen to prevent clogs and maintain reliable operation, protecting your home from potential water damage.
Review Your Water Bills and Look for Hidden Leaks
Unexplained spikes in your water bill often point to hidden leaks. Compare your monthly statements for irregularities. If your usage rises suddenly without increased activity, use your water meter to test for leaks:
- Turn off all faucets and water-using appliances.
- Check the meter reading.
- Wait 30 minutes and recheck.If the numbers change, a hidden leak exists somewhere in the system.
Schedule a Professional Plumbing Inspection Annually
While a homeowner inspection can uncover many issues, scheduling a professional plumbing inspection once a year is invaluable. Experienced plumbers use specialized tools, such as video camera inspections and pressure tests, to detect problems invisible to the naked eye. Relying on experts like Home Alliance ensures that even hidden leaks, corrosion, or blockages are identified early, preventing costly repairs and maintaining the efficiency of your plumbing system.
