A slow drip behind a wall. A water bill that keeps creeping up. A faint musty smell you can't quite place. These are the kinds of signs that often get ignored - until they turn into a much bigger, more expensive problem.
Plumbing leak detection is one of the most important things a homeowner can do to protect their property, and in the Greater Vancouver area, where older housing stock is common and wet winters put extra strain on home systems, catching a leak early can save you thousands. If your water heater, boiler, or HVAC system is showing signs of trouble, our team at Eco Pro is here to help.

Water damage is one of the most costly home repairs a homeowner can face. What starts as a minor leak can quietly cause structural damage, promote mould growth, and compromise insulation - all before you ever notice a visible problem.
The challenge is that many leaks don't announce themselves clearly. They develop slowly, often hidden inside walls, under floors, or behind appliances like water heaters and boilers. By the time you see water staining or feel soft flooring, the damage is already done.
Early plumbing leak detection gives you the chance to address problems before they escalate. It's not just about fixing pipes - it's about protecting your home's structure, your indoor air quality, and your wallet.
You don't need to be a plumber to notice the early warning signs. Here are the most common indicators that something may be leaking in your home.
Your water bill has gone up unexpectedly. If your usage habits haven't changed but your bill has risen, a hidden leak is often the culprit. Even a slow, steady drip can waste hundreds of litres of water per month.
You hear running water when nothing is on. If you can hear the faint sound of water moving through pipes when no taps or appliances are running, it's worth investigating.
There are damp spots, staining, or bubbling paint. Water staining on ceilings or walls, or paint that's bubbling and peeling, often points to moisture behind the surface.
Your water pressure has dropped. A sudden or gradual drop in water pressure across your home can indicate a leak somewhere in the supply line.
There's a musty or mouldy smell. Even without visible mould, persistent musty odours in certain areas of your home can signal moisture buildup from a hidden leak.
Your water heater or boiler area shows signs of moisture. Puddles, rust, or corrosion around your water heater or boiler are serious red flags that shouldn't be ignored. These systems are under constant pressure, and a leak near them can quickly become a safety issue.
Understanding where leaks tend to develop can help you know where to look - and what to watch for.
Water heaters are a leading source of household leaks. Over time, the tank can corrode from the inside out, or the pressure relief valve can begin to fail. Sediment buildup - common in areas with harder water - accelerates wear and can cause the tank to crack or leak from the base.
If your water heater is more than 10 years old, regular inspection is important. A leaking water heater can cause significant floor and wall damage in a short period of time. Learn more about water heater installation and when replacement makes sense.
Boilers circulate hot water or steam throughout your home, and any leak in the system can reduce efficiency, cause pressure drops, and lead to corrosion in surrounding materials. Leaks often develop at pipe joints, valves, or the heat exchanger itself.
Because boiler systems are pressurized, even a small leak can indicate a larger underlying issue. If you notice moisture around your boiler, drops in system pressure, or hear unusual sounds during operation, these are signs worth acting on promptly. Our boiler installation and service team can assess whether a repair or replacement is the right move.
The pipes that carry water to and from your fixtures can develop pinhole leaks over time, especially in older homes. Copper pipes can be susceptible to pitting corrosion, and older galvanized steel pipes degrade from the inside, reducing flow and eventually leaking.
Anywhere pipes connect - to appliances, to fixtures, or to each other - there's a potential failure point. Fittings can loosen, seals can dry out, and compression joints can fail under repeated temperature changes. This is especially relevant in heating systems where pipes expand and contract with each heating cycle.

Professional plumbing leak detection uses a range of tools and techniques to locate leaks without tearing into walls or floors unnecessarily.
Some of the most common methods include:
Pressure testing - the system is pressurized and monitored to see if it holds. A drop in pressure over time confirms a leak somewhere in the line.
Thermal imaging - infrared cameras detect temperature differences in walls and floors that indicate moisture presence. This is one of the most effective non-invasive methods available.
Acoustic detection - specialized listening devices can pick up the sound of water escaping from a pipe, even through concrete or drywall.
Moisture meters - these tools measure moisture levels in building materials and can confirm whether a damp area is actively wet or has dried out.
The right approach depends on the type of system, the age of your home, and where the leak is suspected. A qualified technician can assess the situation and recommend the most effective detection method.
If you think you have a leak, here's what to do right away.
First, check your water meter. Turn off all water-using appliances and fixtures in your home, then check your meter. If it's still moving, water is escaping somewhere.
Second, locate your main shutoff valve. Know where it is and how to use it. If a leak is causing active damage, shutting off the water supply buys you time.
Third, don't ignore small signs. A drip that seems minor today can become major water damage within weeks. The sooner you act, the lower your repair costs are likely to be.
Finally, contact a qualified technician. If the source of a leak isn't obvious, or if it's coming from a water heater, boiler, or heating system, it's important to have a professional assess it. These systems involve both water and either gas or electricity, so they carry safety risks beyond typical plumbing.
Preventing leaks is always easier - and cheaper - than dealing with them after the fact. Here are a few practical steps to reduce your risk.
Schedule regular maintenance on your water heater and boiler. Annual servicing keeps these systems running efficiently and gives a technician the chance to catch early signs of wear before they turn into leaks.
Know the age of your appliances. Most water heaters have a lifespan of 10 to 15 years. Boilers can last longer with proper maintenance, but components like valves and seals have shorter service lives. Keeping track of the age of your equipment helps you plan ahead.
Inspect visible pipes periodically. Take a look under sinks, around your water heater, and near your boiler a few times a year. Look for any signs of moisture, rust, or mineral buildup.
Monitor your water bill. A sudden or gradual unexplained increase is one of the easiest early indicators of a hidden leak.
Sometimes plumbing leak detection reveals that a repair isn't enough. If a water heater is leaking due to internal corrosion, patching it won't solve the underlying issue - replacement is the safer, more cost-effective path. The same applies to aging boilers with repeated pressure problems or cracked heat exchangers.
In these cases, upgrading to a new, more efficient system can actually save money in the long run - especially when you factor in improved energy efficiency and reduced risk of future failures.

What is plumbing leak detection?
Plumbing leak detection is the process of identifying the source and location of water leaks in a home's plumbing or heating system. It can involve pressure testing, thermal imaging, acoustic equipment, and moisture meters to find leaks without unnecessary damage to walls or floors.
How do I know if I have a hidden water leak?
Common signs include an unexplained rise in your water bill, damp spots or staining on walls or ceilings, reduced water pressure, a musty smell in certain rooms, or the sound of running water when nothing is in use.
Can a leaking water heater be repaired, or does it need to be replaced?
It depends on the cause and extent of the leak. Minor valve or fitting leaks are often repairable, but if the tank itself is leaking due to corrosion, replacement is usually the better option. A technician can assess which applies to your situation.
How often should I have my boiler inspected for leaks?
Annual servicing is recommended for most boiler systems. Regular maintenance checks pressure, seals, valves, and connections - all of which are common leak points - and helps catch issues before they become serious.
Is a small drip really worth worrying about?
Yes. Even a slow drip can cause significant water damage over time and lead to mould growth inside walls or floors. Addressing small leaks early is almost always less expensive than dealing with the damage later.
