You might not think about it often, but plumbing inspections are one of the unsung heroes of home maintenance. Many folks in Seattle and the surrounding area might not think twice about it, chalking it up as just another line item on their to-do list, but skipping this step could mean setting yourself up for a nasty surprise down the road. Imagine waking up to a flooded basement or a failed water heater just as the cold weather hits – suddenly, a simple home inspection plumbing seems like a small price to pay.
In this post, I’ll guide you through what a plumbing inspection is, the types available, and, most importantly, why it’s something you should consider. By the end, you’ll see how a proactive approach can protect your home, save you from emergency calls, and keep your house plumbing inspection in top shape.
What Is a Plumbing Inspection?
Simply put, a plumbing inspection is a check-up on your home’s water and sewer system. Think of it like a physical exam for your pipes, drains, fixtures, and water appliances. A qualified plumber comes in to assess the health of your system, looking for any signs of wear, leaks, or issues that could escalate if ignored. This isn’t just a casual glance – it’s a structured process to catch things that may not be obvious at first sight.
Types of Plumbing Inspections
Visual Inspection
A visual examination is the most straightforward. Our plumbers walk around, examine the visible pipes, fixtures, and drains, and assess their condition. This often catches corrosion, leaks, and other surface-level issues. It’s an important first step because sometimes, all it takes is a quick look to spot early warning signs.
Camera Inspection
When a simple glance isn’t enough, we bring out the big guns — the camera plumbing and sewer inspection. We feed a tiny camera into your pipes, typically focusing on your drains and sewer lines. This allows us to see any blockages, root invasions, or pipe breaks that could cause backups or structural damage. These are particularly valuable for older homes or if you’ve experienced recurring clogs.

Why Should You Get a Plumbing Inspection?
Protect Your Home
One of our clients in Seattle called me about a ‘small leak’ in their basement. By the time I arrived, the situation was anything but small. A routine review of their pipes could’ve caught that leak early on and saved them thousands in repair costs. Regular plumbing testing helps spot small problems before they become big headaches. A professional eye can often detect things you might miss.
Selling or Buying a Home
If you’re planning to sell, a plumbing inspection can be a selling point – potential buyers like to know the home’s system is in top condition. On the flip side, if you’re buying, it is crucial. We can’t tell you how many clients have dodged massive plumbing issues thanks to pre-purchase examinations. A thorough final plumbing inspection gives you a clear understanding of any potential fixes or replacements so you can make informed decisions.
Avoid Costly Plumbing Emergencies
We always say, an ounce of prevention is worth a pound of cure – especially when it comes to inspecting your system. Water and sewer pipe examinations prevent those costly emergencies that tend to strike at the worst possible time. A busted pipe or a failing water heater isn’t just expensive; it can be downright disruptive.
What Does a Plumbing Inspection Include?
To get an idea of what we cover, here is a sample of our plumbing inspection checklist:
- Water Heater Inspection: Water heaters often go unnoticed until they stop working. We’ll check for any signs of wear, leaks, or issues with temperature settings that could indicate a problem down the line.
- In-Depth Examination of Exposed Plumbing: From pipes under sinks to basement lines, we look for any signs of corrosion, damage, or leaks.
- Examine Fixtures and Caulking: Fixtures might seem harmless, but cracked caulking or loose fittings can lead to slow, insidious leaks.
- Examine Insulation: In Seattle’s cold seasons, pipe insulation is a must. We’ll check that your pipes are insulated properly to prevent freezing and bursting.
- Check for Lead Pipes: Lead pipes are still common in older homes. While the health risks are well-known, many people aren’t aware if they have lead pipes. We’ll recommend safe replacement options if necessary. We can replace your old pipes with PEX tubing or copper piping, which are both safe and durable solutions. Learn more about PEX repiping or explore our copper pipe services.
- Video Inspection of Drains and Sewer Pipes: For a more comprehensive look at your drainage system, we’ll use a camera to check for clogs, cracks, or roots. This is especially valuable if you have old pipes or have noticed slow drains.
- Sump Pump Inspection: Your sump pump protects your basement from flooding, especially during Seattle’s rainy season. We’ll ensure it’s in good working condition.

How a Plumbing Inspection Actually Works
A plumbing inspection isn’t just a quick glance under the sink — it often involves a full check-up of a home’s plumbing system. The goal is to assess whether everything is working safely and efficiently, and to identify any signs of trouble early.
Our licensed plumber begins by walking through your property and reviewing accessible fixtures and visible plumbing components. These might include faucets, toilets, sinks, drains, shut-off valves, water heaters, and sometimes exterior hose connections. During this process, they look for issues like corrosion, moisture damage, slow drainage, or other signs that may indicate a deeper problem.
Depending on the home’s age or prior plumbing concerns, additional tools such as video cameras may be used to inspect deeper within the system. This can help identify hidden cracks, clogs, or root intrusions — often without the need for digging.
Whether it’s part of routine maintenance or a pre-sale home evaluation, the inspection can provide valuable insight into the health of the plumbing system.
How often should I have my plumbing inspected?
Ideally, our professional plumber should take a look at your system annually, especially for older homes or properties with a history of issues. However, if you’ve had recent problems, noticed signs like slow drainage or leaks, or live in an area with harsh weather, more frequent check-ups can help catch potential problems early and avoid costly repairs.

Common Issues That Inspections Help Uncover
Even small plumbing issues can lead to significant damage if left undetected. Regular inspections often help uncover:
- Minor leaks under sinks or behind walls
- Signs of aging or worn-out water heaters
- Reduced water pressure due to mineral buildup
- Corroded pipe joints or fittings
- Cracks in drain lines
- Early signs of blockages or root intrusion in sewer lines
Identifying these problems early can help homeowners address them before they escalate into costly emergencies.
How to Prepare for a Plumbing Inspection
A bit of preparation can help make the inspection process more efficient. Ensure that areas around sinks, appliances, and other plumbing fixtures are accessible. If there have been recent plumbing issues, it’s helpful to let the plumber know in advance so they can pay special attention to those areas. Additionally, securing pets during the visit helps ensure safety and efficiency.
The Tools Behind the Inspection
Modern plumbing inspections often go beyond just visual checks. In some cases, and depending on a visual inspection and potential issues you may be having, we may use specialized tools like inspection cameras, thermal imaging, or pressure gauges to get a clearer picture of what’s happening inside pipes. These technologies can improve the accuracy of the inspection and help detect issues that aren’t visible to the naked eye.
What Does a Home Plumbing Inspection Cost?
The cost of a home plumbing inspection can vary significantly based on several factors, including the size of your home, the complexity of your system, and the type of inspection needed. For example, a basic visual assessment might cost less than a comprehensive plumbing and sewer inspection that involves specialized camera equipment. Additionally, older homes or properties with extensive plumbing systems may require a more detailed assessment, which can impact the price.
To ensure you’re getting an accurate estimate, it’s best to consult a professional who can assess your specific situation and provide a quote. Investing in a thorough assessment often pays off in the long run by catching issues early and helping you avoid costly repairs.
