Leak Detection Process

How We Find and Repair Plumbing Leaks

Finding a leak starts with understanding where the water is showing up, what fixtures are nearby and how the plumbing is arranged behind the finished surfaces.

John The Plumber & Drain Cleaning uses the visible symptoms, plumbing layout and accessible connections to narrow down the likely source before recommending the appropriate repair.

01
Start With the Symptoms

Tell Us What You're Seeing

We begin with the location of the moisture, when it appears, which fixtures are being used and any other clues you've noticed.

02
Inspect the Plumbing

Narrow Down the Likely Source

Our plumber checks nearby fixtures, supply lines, shutoff valves, visible piping and accessible connections to determine where the water may be coming from.

03
Explain the Problem

Review the Repair Options

Once the likely source is identified, we'll explain what is leaking, what may have caused it and the practical options for repairing the problem.

04
Repair & Test

Fix the Leak and Check the Result

After the repair is completed, the affected plumbing is tested and the accessible connections are checked to make sure the leak has been addressed.

Leak Detection FAQs

Frequently Asked Questions About Plumbing Leaks in Ottawa

Plumbing leaks can happen almost anywhere in or around the home. These answers cover common indoor and outdoor leak concerns, how leaks are investigated and when professional repair may be needed.

How do I know if I have a hidden plumbing leak?

Hidden leaks may show up as ceiling stains, damp drywall, warped flooring, musty odours, unexplained moisture or the sound of water running when fixtures are off. An unexpected increase in water use can also be a clue that water is escaping somewhere in the plumbing system.

Can plumbing leaks happen anywhere in the home?

Yes. Leaks can develop at kitchen and bathroom fixtures, toilets, water heaters, shutoff valves, supply lines, basement plumbing, pipes behind walls and ceilings, or other accessible plumbing connections. If you know water is appearing but do not know where it is coming from, professional leak detection and repair can help narrow down the source.

Can plumbing leaks happen outside the house too?

Yes. Exterior plumbing can leak as well. Outdoor faucets, exterior water connections and accessible piping may develop leaks from wear, damaged components or seasonal conditions. If the problem involves an outdoor tap, our outdoor faucet repair service may be the appropriate next step.

Why is water showing on my ceiling if there is no plumbing directly above it?

Water can travel along framing, pipes and building materials before it becomes visible. The stain you see may not be directly below the source. Nearby bathrooms, supply lines, drains and other plumbing should be considered when investigating a ceiling leak.

What can cause a leak underneath a kitchen or bathroom sink?

Under-sink leaks can come from faucet supply lines, shutoff valves, drain connections, fittings or the faucet itself. If the fixture is part of the problem, we also provide faucet installation and replacement throughout Ottawa.

Can a toilet leak without water pooling on the bathroom floor?

Yes. Some toilet leaks are internal and may cause the toilet to run repeatedly or use more water than normal without creating a visible puddle. Other leaks can occur around the supply connection, tank components or base. Our toilet repair service can help with common toilet leaks and operating problems.

What should I do if my water heater is leaking?

Water around a water heater may come from valves, fittings, plumbing connections or the tank itself. Because a tank failure can release a significant amount of water, the source should be investigated promptly. Visit our water heater services page for more information.

What if the leak is coming from a damaged pipe?

If the pipe itself is cracked, corroded, damaged or leaking at a fitting, the affected section may need to be repaired or replaced. Our pipe repair and retrofit services are available for many types of residential plumbing pipe problems.

Is a plumbing leak always an emergency?

Not every leak is an emergency, but active water flow, rapidly spreading water damage, a burst pipe or a situation you cannot safely control should be addressed quickly. For urgent plumbing problems, visit our emergency plumbing service .
