When it comes to owning a home or managing a property, few things are as important as ensuring the plumbing is up to scratch. A plumbing inspection can reveal hidden issues that, if left unchecked, could lead to costly damage and major headaches. Whether you’re preparing for a routine check, a property sale, or just trying to stay on top of maintenance, knowing how to prepare for a plumbing inspection can save you both time and money.
In this guide, we’ll walk you through exactly what to expect and how to get your home inspection-ready like a pro.
Why Do You Need a Plumbing Inspection?
Plumbing inspections are more than a box to tick. They serve as a critical checkpoint for:
- Identifying leaks (even the sneaky ones behind walls),
- Checking for corrosion or damage in pipes,
- Ensuring water pressure and drainage systems are functioning properly, and
- Confirming your plumbing complies with local regulations.
They’re especially important before selling or buying a home, after major renovations, or as part of regular maintenance for older properties.

Types of Plumbing Inspections
Before your plumbing inspection, it’s always wise to have a clear summary of all your key plumbing issues, from recurring leaks to past repairs, to ensure nothing is overlooked and your inspector can address all your concerns efficiently. Before we dive into preparation, it helps to understand the different kinds of inspections you might encounter:
1. Visual Inspection
This involves a qualified plumber examining visible pipes, fixtures, taps, drains, and toilets. It’s the most common type and doesn’t require any invasive procedures.
2. Camera Inspection
For issues underground or inside walls, plumbers may use a small CCTV camera to inspect the inside of your pipes.
3. Pressure Testing
This test checks your water pressure and helps detect hidden leaks in closed systems.
4. Backflow Testing
Especially important for properties with irrigation or sprinkler systems, this test ensures that contaminated water isn’t flowing back into your clean water supply.
Step-by-Step: How to Prepare
Let’s break down how to prepare for a plumbing inspection so that everything runs smoothly and efficiently.
1. Clear the Way
Start by making all plumbing areas easily accessible. This includes:
- Cupboards under the kitchen and bathroom sinks,
- The hot water system,
- The water meter,
- Outdoor taps, and
- Access points to crawlspaces or basements.
Remove personal items or storage boxes so the plumber has space to inspect and test fixtures without obstruction. Think of it like preparing for a cleaner — the less clutter, the quicker the job.
2. Check for Obvious Issues
Do a quick DIY inspection before the plumber arrives. Look out for:
- Dripping taps,
- Slow-draining sinks or showers,
- Unusual noises (like gurgling or banging),
- Signs of mould or water stains on ceilings or walls, and
- Low water pressure.
Fixing minor issues ahead of time not only helps the plumber focus on bigger problems but also makes you look like a proactive homeowner.
3. Know Your Plumbing History
If you’ve had previous work done or repairs made, try to gather any paperwork, invoices, or warranty information. This helps the inspector understand what changes have been made and whether certain issues are recurring. It’s also handy to know:
- The age of your pipes,
- The last time your hot water system was serviced, and
- Whether you’ve had any drainage problems in the past.
4. Test All Fixtures
Walk through your home and check that every tap, toilet, shower, and appliance that uses water is functioning. Note anything that seems off — even if it seems minor. For example:
- Does the toilet continue running after flushing?
- Does the kitchen tap spray sideways?
- Is the washing machine inlet leaking slightly?
The more info you can give the inspector, the more efficient (and accurate) the inspection will be.
5. Locate the Main Shut-Off Valve
This is a simple but often overlooked step. Make sure you know where your main water shut-off valve is — and that it’s working. If the inspector needs to test or turn off the water supply, this will speed things up and prevent any unnecessary searching or delays.
Bonus points if you also know where your sewer clean-out or stormwater outlets are. This is especially helpful if you’ve previously experienced blocked storm water drains, as knowing these access points allows plumbers to quickly inspect and clear potential buildup, debris, or root intrusion before it causes flooding or property damage.
6. Secure Pets and Kids
A friendly dog might be your best mate, but they’re not always a plumber’s best friend. On inspection day, make sure pets are secured and children are supervised or occupied. It ensures safety for everyone and allows the plumber to focus without distraction.
7. Ask Questions and Take Notes
A plumbing inspection isn’t just a report card — it’s a learning opportunity. Don’t be shy about asking questions, especially if you don’t understand the jargon. Ask things like:
- How urgent is this issue?
- Can I fix this myself?
- Is this a common problem for homes in this area?
Taking notes will help you prioritise future repairs and make more informed decisions about maintenance or renovations.
After the Inspection: What’s Next?
Once the inspection is complete, the plumber will usually provide a report or summary. This might include:
- A list of issues found,
- Recommendations for repairs or upgrades,
- Cost estimates,
- Photos (especially for camera inspections), and
- A timeline for when issues should be addressed.
Even if everything looks good, keep the report on file for future reference or when selling the property.
Common Issues Found During Inspections
If you’re curious about what typically shows up during inspections, here’s a quick list:
- Corroded or old galvanised pipes,
- Tree root intrusion into sewer lines,
- Leaky fixtures or toilets,
- Poor water pressure,
- Non-compliant installations,
- Improper drainage or backflow issues.
Preparing for a Plumbing Inspection
Preparing for a plumbing inspection doesn’t need to be stressful. With a bit of effort and planning, you’ll not only help the process go faster, but you’ll also get a clearer picture of your home’s overall condition. Regular plumbing inspections can prevent emergencies, protect your investment, and give you peace of mind — one pipe at a time.
Remember: a good plumbing system is mostly invisible — until it isn’t. So, whether you’re dealing with a decades-old bungalow or a newly built home, taking the time to prepare properly will always pay off.
