How To Perform A Plumbing Inspection

Maintaining a home involves numerous aspects, and often, the plumbing system is one area that gets overlooked. However, the importance of a well-functioning plumbing system, from ensuring a warm shower to facilitating the essential functionality of a kitchen sink, is immense. Therefore, the ability to perform a plumbing inspection is a vital skill. This guide will walk you through the process step-by-step.

Understanding The Basics

Before initiating the inspection, it’s critical to understand the basics of a home plumbing system. The system consists of two parts: one that brings fresh water in and another that takes wastewater out. Pressurized water flows to your faucets and appliances, while gravity aids in the disposal of waste and used water from the house.

This understanding is a starting point. However, if you’re unsure or hesitant about any aspect of your plumbing system, it’s always best to consult plumbers in Greenwood Indiana or the ones nearest your location who have the necessary tools and skills for the job.

Whether you employ professional help or do the task yourself, here are the necessary steps to take when performing a complete plumbing inspection:

1. Leak Inspection

How To Perform A Plumbing Inspection

Begin the process by checking for leaks, which can lead to water waste, higher utility bills, and even property damage. To inspect for leaks, start by looking for visible signs of water damage around pipes, such as discoloration or warping.

You can also run your fingers along the pipes to feel any moisture. If you suspect a leak, use a flashlight to inspect the area more closely. Look for cracks or pinholes in the pipes, as well as loose or corroded fittings.

If you find a leak, it’s important to address it promptly to prevent further damage.

2. Water Pressure Assessment

Next, evaluate the water pressure in your home. Low pressure could indicate a leak or blockage, while high pressure can lead to damaged pipes and fixtures. You can measure the pressure at an outdoor spigot using a pressure gauge.

A reading between 40 to 65 psi is typically considered ideal. If the pressure lies outside this range, consider installing a pressure regulator or calling a professional for help.

3. Shut-off Valves Checking

Shut-off Valves Checking

Another important step in a plumbing inspection is checking the shut-off valves. Shut-off valves are essential for controlling the flow of water in your home and can help prevent water damage in the event of a leak or burst pipe.

To check the shut-off valves, start by locating them. There should be a valve for each fixture and appliance that uses water, as well as a main shut-off valve for the entire house. Make sure each valve is in good condition and can be easily turned on and off. If you find a valve that is difficult to turn or appears to be damaged, it’s important to have it repaired or replaced as soon as possible.

4. Water Heater Examination

It’s also important to examine your water heating system. Look for any signs of rust or corrosion on the tank and any water on the floor around it. Also, inspect the pressure relief valve, a critical safety device that prevents the water heater from over-pressurizing and potentially causing damage.

When examining the water heater, take note of the water heater’s age as well. Most heaters last between eight to 12 years. If yours is nearing or beyond this range, it might be time to think about a replacement.

5. Drainage System Inspection

Drainage System Inspection

The drainage system is another important area to inspect during a plumbing inspection. A clogged drain can cause water to back up and potentially cause damage to your home, while a leak in the drainage pipes can lead to foul odors and unsanitary conditions.

To check the drainage system, start by running water in each sink, shower, and bathtub to ensure that it drains properly. If you notice slow drainage or gurgling sounds, it could be a sign of a clog. In addition, inspect the pipes for any signs of leaks, such as water stains or dampness.

Finally, check the cleanouts, which are access points to the drainage system. Make sure they’re in good condition and can be easily accessed in case of a clog or other issue.

6. Water Quality Evaluation

The final aspect of a complete plumbing inspection water quality evaluation. Discoloration of water or the presence of strange taste or peculiar smell can indicate a problem with your water supply. It’s also essential to note that if you observe your soap not lathering as well as it should, or if there are stains on your fixtures, you may be dealing with hard water. This might necessitate the installation of a water softener.


Plumbing inspection isn’t a task to be taken lightly. A slight fault in your plumbing system can be dangerous as it results in property damage and health risks. Regular checks can help you resolve any issues before they escalate.

It’s recommended to perform a plumbing inspection at least once a year, or more frequently if you notice any issues.
