What to Expect During a Home Plumbing Inspection

Get a clear idea of what plumbers inspect and why regular checks matter

Plumbing is the most important system in any home. It supplies clean water, takes away waste, and plays the third important role of overriding the first two and keeping everything working smoothly. But most people only think about their inspection and repair when something breaks.

A water heater making unusual noises or not heating properly may have sediment buildup. A toilet that constantly runs or clogs frequently could have a faulty valve or seal. If your sump pump fails to start during heavy rain or vibrates strangely, it might have a mechanical issue that needs checking.

Regular plumbing inspections help avoid major repairs. They also help keep your home safe and running efficiently. In this blog, you’ll learn everything about home plumbing inspections. We will take you through it step by step, so you understand what happens and why it is important.

Why Plumbing Inspections Matter

Plumbing inspections identify issues early. They prevent minor leaks from developing into serious problems. Plumbing inspections save money, up to thousands of dollars, in repairs. A small leak can lead to mold, water damage, or even structural damage. You might not notice these issues immediately, but they develop rapidly.

Professional plumbers have the training and equipment to detect problems. They also inspect areas you might overlook. You don't have the anxiety of unexpected repairs. Rather, you get ahead of issues.

Homeowners tend to neglect inspections until there's an issue. However, consistent check-ups provide reassurance. They make your plumbing system last longer and perform better.

When to Get a Plumbing Inspection?

Most professionals suggest a plumbing inspection every two years. Older homes require more frequent inspections. If your home is more than 40 years old, an annual check is ideal.

You should also have an inspection before purchasing a home. A standard home inspection tests whether the toilets flush and the taps run. It does not test the entire plumbing system. A complete inspection by a licensed plumber entails much more. It detects hidden leaks, burst pipes, or drainage issues.

Should it ever come to selling your house, having an inspection done will be worth every penny. It tells buyers that the plumbing is working well. It can also get the sale going faster.

Plumbing Inspection Types

Two kinds of plumbing inspections exist: one is a visual inspection, and the other is a camera inspection. The aim of both is to keep the functional system safe.

• Visual inspection: A visual inspection means checking faucets and pipes, drains, and flow control valves. It's an easier job than most homeowners believe. They check all areas, particularly for leaks, corrosion, and damage. Then the plumber checks the sinks, toilets, showers, water heater, and main valve.


• Camera inspection: The camera inspection is more specialized. The plumber inserts a high-definition camera inside the sewer line to inspect the pipe for any visible cracks, buildup, or clogs. Such inspection is useful in preventing sewer backups and other expensive repairs.

10 Vital Steps During a Plumbing Inspection

• A plumbing check inspects everything in the system. Plumbers investigate places where water enters and exits your home. They include bathrooms, kitchens, laundry areas, basements, and outside-the-home areas.


• Plumbers check bathroom toilets flushing and filling properly, inspect flappers and filling systems for leaks, and inspect sink, tub, and shower drains for blockage and water pressure.


• Plumbers check faucets, shut-off valves, and supply lines inside the house. They test for corrosion and slow drains. Dishwashers and garbage disposals can be checked as well.


• In the laundry room, plumbers inspect washer connections and floor drains. They check that water flows and drains correctly.


• Outside the house, they inspect hose bibs and outdoor faucets. They check that these fixtures are freeze-proofed. This is particularly important in cold climates.


• They check the shut-off valve for the main water supply. This valve has to function in an emergency. Plumbers make sure it operates freely and cuts off water effectively.


• They check the water heater. Plumbers check the pressure relief valve. They take water temperature readings. They check connections and for leaks. If necessary, they drain the tank to clear sediment.


• Sump pumps are also inspected. They check whether the pump is functioning and whether it is pushing water as it should, especially in homes that have basements and crawlspaces.


• Sewer lines are inspected with a camera for underground pipes. The camera exposes cracks, roots, or misalignment. These issues clog drains or lead to a collapse.


• If your home has a water filtration system, they inspect that too. Plumbers check for leaks and confirm that filters are working.

Cost of a Plumbing Inspection

A plumbing inspection price will vary based on its thoroughness. A simple visual inspection will probably cost about $200. This includes checking all exposed plumbing and fixtures.

If you need a camera inspection, the price increases. These can run $300 to $500 or more. The camera inspection is worth it because it detects unseen issues.
If you combine a plumbing inspection with a home inspection, it usually saves some money. Always ask what is included.

What a Home Inspector Looks for in Plumbing

If you are purchasing a home, a basic home inspector performs a general check. They run toilets, turn on faucets, and ensure drains function. They find the main shut-off valve. They inspect the water heater and its connections.

They check toilets for leaks and the level of fill in the tank. They inspect sinks and showers for water pressure and drainage. They examine sump pumps if the house is equipped with one. They also inspect for leaks or water damage that is apparent.

But this inspection alone isn't enough to bring about full peace of mind. A plumber examines further and employs specialized equipment.

What a Plumber Searches for on a Complete Inspection

In a complete plumbing inspection, the plumber inspects everything.

He or she checks for safety and efficiency in the water heater. They check toilets for flushing performance, fill rate of the tank, and internal components. They check all pipes for cracks or leakage. They check faucets and drains for correct flow and pressure.

They also check outdoor fixtures for freeze protection. They find and test the main shut-off valve. They inspect sewer pipes with a camera for damage that is not visible. They check water filtration systems. They test sump pumps and adjacent hydrants.

This complete check helps avoid emergencies and expensive repairs.

What You Can Do Between Inspections

• Between inspections, stay vigilant. Check for leaks. Inspect under sinks and toilets. If you notice water stains or wet areas, have a plumber fix them immediately.


• Identify where your main shut-off valve is. You might have to shut off the water in an emergency.


• Insulate outside pipes in cold temperatures. Frozen pipes might burst and cause extensive damage.


• Replace worn-out washers, flappers, and seals if you experience dripping. These little repairs avoid larger issues.


• If your house is old, begin saving for upgrades in the future. Plumbing systems don't last forever. Being prepared decreases stress later.

Final Thoughts

A plumbing inspection is a wise investment. It catches minor issues early. It prevents leaks, mold, and expensive damage to your home. Whether you are selling, buying, or simply keeping up your home, routine inspections are sensible.

Have a licensed plumber perform a full inspection. For optimal results, opt for visual and camera inspections. Include plumbing in your home maintenance routine.

The cost of average inspections is much less than that of costly repairs. Prevent problems down the line and keep your system functioning properly. Get informed, get safe, and safeguard your home with periodic plumbing inspections.
