Common Plumbing Issues Found in Home Inspections

When it comes to home inspections, plumbing issues are among the most common problems encountered. These issues, if left unaddressed, can lead to costly repairs and significant water damage. In this blog, we'll explore some of the most frequent plumbing problems found during home inspections and provide tips on how to identify and address them.

1. Leaky Faucets and Pipes

One of the most common plumbing issues is leaky faucets and pipes. While a small drip might seem insignificant, it can waste a considerable amount of water over time and lead to higher utility bills. During a home inspection, inspectors will check all faucets and exposed pipes for signs of leaks.

Tip: Regularly inspect under sinks and around appliances for any signs of moisture or dripping. Replace worn-out washers and seals to prevent leaks.

2. Clogged Drains

Clogged drains are a frequent issue, often caused by the buildup of hair, grease, soap scum, and other debris. Inspectors will check sinks, tubs, and showers for slow drainage, which can indicate a clog.

Tip: Use drain screens to catch debris and avoid pouring grease or coffee grounds down the sink. Regularly clean your drains with a mixture of baking soda and vinegar to keep them clear.

3. Running Toilets

A running toilet can waste up to 200 gallons of water per day. This issue is usually caused by a faulty flapper valve, a worn-out seal, or an improperly adjusted float.

Tip: Check your toilet for running water by adding a few drops of food coloring to the tank. If the color seeps into the bowl without flushing, you have a leak. Replace the flapper or adjust the float as needed.

4. Low Water Pressure

Low water pressure can be a frustrating issue for homeowners. It is often caused by sediment buildup in pipes, corroded plumbing, or a problem with the local water supply.

Tip: Regularly clean faucet aerators and showerheads to remove mineral buildup. If the problem persists, consult a plumber to check for more serious issues.

5. Water Heater Problems

Water heaters are a critical component of any home's plumbing system, and they can develop issues such as leaks, insufficient hot water, or strange noises. Inspectors will check the water heater for signs of rust, corrosion, and proper venting.

Tip: Flush your water heater annually to remove sediment buildup. Inspect the unit for leaks and ensure the pressure relief valve is functioning correctly.

6. Faulty or Outdated Fixtures

Outdated or faulty plumbing fixtures, such as old faucets, showerheads, and toilets, can cause leaks and inefficiencies. Inspectors will check for signs of wear and tear on these fixtures.

Tip: Consider upgrading to modern, water-efficient fixtures. Not only will this improve the functionality of your plumbing system, but it can also save you money on water bills.

7. Sewer System Issues

Problems with the sewer system can be severe and costly to repair. Common issues include tree root intrusion, collapsed pipes, and blockages. Inspectors may recommend a sewer scope inspection to identify these problems.

Tip: Be mindful of what you flush down the toilet and avoid planting trees or shrubs near sewer lines. Regularly inspect and maintain your sewer system to prevent major issues.


Addressing common plumbing issues early can save homeowners from significant expenses and headaches down the line. Regular maintenance and inspections are key to keeping your plumbing system in good working order. If you’re buying a home, ensure that the home inspection includes a thorough check of the plumbing system. For current homeowners, proactive maintenance can help you avoid many common plumbing problems.

By staying vigilant and addressing issues as they arise, you can ensure that your home's plumbing system remains efficient and reliable. For more tips and advice on home inspections and maintenance, be sure to check out our other blog posts!
