Most people only call a plumber after something goes wrong. A pipe bursts, a drain backs up, or the hot water suddenly stops.
But these problems don’t start with a bang. They begin as tiny leaks and slow wear behind your walls and under your floors, and they build for months before you notice.
Once a Year Is the Rule of Thumb
Plan for one plumbing inspection every year.
For most homes, that is the right pace. An annual plumbing inspection finds leaks, worn parts, and early clogs while they are still small and cheap to fix, before they turn into a bigger repair and a bigger mess.
Some homes need to be checked more often than that. Next, we’ll look at which ones.
How Often Should Plumbing Be Inspected? It Depends on Your Home
Once a year
- Most homes with regular use
- Homes with a basement or sump pump
- Homes with a tank water heater
Every 6 months
- Homes older than 40 years
- Homes with clay, cast iron, or galvanized pipes
- Homes with large trees near the sewer line
- Homes with past leaks or backups
Before you buy or sell
- Always, no matter how new the home is
After a big event
- A major storm or flood
- A freeze
- A renovation
Why a Yearly Home Plumbing Checkup Matters
A home plumbing checkup is a lot like a doctor visit. You feel fine, but a pro can spot things you can’t.
Here is what a yearly check can do:
- Find small leaks before they damage walls and floors
- Catch worn parts before they fail
- Keep water pressure steady
- Protect your water heater and pipes
- Save you from surprise emergencies
This is the heart of preventive plumbing maintenance for homeowners. A small visit now helps you avoid a big problem later.
What Happens During a Residential Plumbing Inspection?
People often wonder what an inspector really does. Here is the plumbing inspection checklist our team follows.
Pipes and Fittings
- Look for leaks, drips, and stains
- Check for rust and corrosion
- Test shutoff valves
- Look at pipe material and age
Drains
- Test how fast each drain empties
- Listen for gurgling
- Look for signs of buildup or roots
Water Heater
- Check for leaks and rust
- Look at the age and condition
- Check the pressure relief valve
- See more on our water heater services
Toilets, Sinks, and Showers
- Look for running or leaking toilets
- Check faucets and supply lines
- Test water pressure
Sump Pump and Basement
- Test the pump and float switch
- Check the pit and discharge line
- Learn more about our sump pump services
Main Water and Sewer Lines
- Check the main shutoff
- Look for signs of sewer trouble
- Add a camera inspection when needed
Gas Lines
- Look for loose fittings or odd smells
- Gas work always needs a licensed pro. See our gas line services.
Should You Add a Camera Inspection?
A normal inspection shows what is visible. But your sewer line is buried.
A sewer camera goes inside the pipe and shows us:
- Cracks and breaks
- Roots growing inside
- Buildup and blockages
- Low spots where water collects
It is a smart add-on if your home is older, your drains are slow, or you are buying a house. Read why it matters in our guide on sewer camera inspection benefits.
Signs You Need a Plumbing Inspection Right Now
Don’t wait for your yearly visit if you notice these signs you need a plumbing inspection:
- Slow drains in more than one spot
- Low water pressure
- Water stains on walls or ceilings
- Musty smells or mold
- Rusty or cloudy water
- Gurgling pipes
- A sudden jump in your water bill
- A water heater that is loud or leaking
- Wet spots in your yard
Even one of these is worth a call. Many of them point to hidden leaks or drain problems.
Whole Home Plumbing Inspection Cost: What Affects It?
Homeowners often ask about whole home plumbing inspection cost. We don’t list set numbers, since every home is different.
Here is what shapes the estimate:
- The size of your home
- The age and type of your pipes
- How many fixtures you have
- Whether you want a camera inspection added
- Whether you have a sump pump, sewage pump, or special systems
- How easy it is to reach your plumbing
We explain everything before we start. If you’d like to spread out the cost of repairs that come up, ask about financing.
Simple Habits Between Inspections
You can help your plumbing last in between visits. Try these:
- Check under sinks once a month for drips
- Know where your main water shutoff is
- Don’t pour grease down the drain
- Use drain strainers in showers and sinks
- Flush your water heater on schedule
- Test your sump pump before storm season
- Keep trees and large roots away from sewer lines
If your drains clog often, regular drain cleaning or hydro jetting can keep them clear.
Myths About Plumbing Inspections
Myth: “If nothing is leaking, I’m fine.”
Many leaks hide inside walls, under floors, or underground.
Myth: “New homes don’t need inspections.”
Even new plumbing can have bad fittings or poor installation.
Myth: “I’ll just wait until something breaks.”
Emergency repairs usually cost more and cause more damage.
Myth: “Hard water doesn’t matter.”
Hard water builds scale in pipes and heaters. A water treatment system can protect them.

Frequently Asked Questions
How often should plumbing be inspected in an average home?
Most homes should have a plumbing inspection once a year. Older homes, or homes with past leaks and backups, may need one every six months. Regular checks help you find small problems before they grow. Our residential plumbing team can set a schedule that fits your home.
What is included in an annual plumbing inspection?
An annual plumbing inspection usually covers pipes, drains, fixtures, your water heater, and your main shutoff valve. We also check for leaks, corrosion, and low water pressure. If you have a basement, we look at your sump pump too. See what we offer on our residential plumbing services page.
Do I need a camera inspection as part of a home plumbing checkup?
It is not always required, but it helps in many cases. A camera inspection lets us see inside your sewer line, where cracks, roots, and clogs are hidden. We recommend it for older homes, repeat clogs, and home purchases.
What are the signs you need a plumbing inspection?
Common signs include slow drains, low water pressure, water stains, musty smells, and rusty water. A sudden rise in your water bill can also point to a hidden leak. If you notice any of these, book a visit with our residential plumbing team right away.
What affects whole home plumbing inspection cost?
The cost depends on your home’s size, your pipe type and age, and the number of fixtures. Adding a camera inspection or checking special systems like a sump pump can also change the estimate. Contact us for a clear quote based on your home.
Is preventive plumbing maintenance really worth it for homeowners?
Yes. Preventive plumbing maintenance helps you find leaks, worn parts, and clogs while they are still small. That means fewer emergencies and less damage to your home. Services like drain cleaning and water heater care are a big part of keeping your system healthy.
Should I get a plumbing inspection before buying a home in Laurel?
Yes. A plumbing inspection before you buy can reveal hidden problems like old pipes, failing water heaters, or damaged sewer lines. This helps you plan repairs and negotiate with confidence. Our team can pair it with a camera inspection for a full picture.
