The moment a pipe starts leaking, knowing what to do makes the difference between a minor fix and major water damage. Shut off the water to the affected area or at the main valve, drain the line by opening a nearby tap, contain the water with towels and a bucket, and call a plumber. The faster you stop the flow, the less damage you deal with.
Even a small leak should not be left. What looks like a slow drip can be hiding a larger problem, and water that reaches drywall, insulation, or flooring causes damage quickly so calling your plumbing company is important. If you feel like the pipe leak is an emergency, call right away. As an emergency plumber in Calgary, we are available 24 hours a day, 7 days a week, with upfront pricing and a 1-year warranty on all parts and labour so call (403) 294-1288 with any questions.
In the meantime, here is exactly what to do:
Step 1: Stop the Water
Your first priority is to stop water reaching the leak. If there is a shut-off valve close to the leaking pipe, such as under a sink or behind a fixture, turn it clockwise to close it. If the leak is on a pipe with no local valve, or you cannot find one, go to your main water shut-off valve and turn it off to stop water to the whole house.
In most Calgary homes the main shut-off valve is in the basement, utility room, or mechanical room near where the water line enters from the street, often close to the water meter.
Find Your Shut-Off Valve Before You Need It
The middle of a leak is the worst time to go looking for your main shut-off valve. Take a few minutes now to locate it, confirm it turns, and make sure everyone in the household knows where it is. A valve that has not been turned in years can be stiff, so knowing in advance that yours works, or that it needs attention, saves you critical minutes when it counts.
Step 2: Drain the Line
Once the water supply is off, open a tap or two that are lower than or near the leak. This drains the water still sitting in the pipe and relieves pressure, which slows or stops the leak while you deal with the rest. For a leak on a hot water line, it also helps to turn off your water heater.
Why Draining the Line Matters
Even after you shut off the supply, water already sitting in the pipes will keep draining out of the leak under its own weight and pressure. Opening lower taps gives that trapped water an easier path out, which pulls it away from the leak and speeds up the point where the dripping stops. It is a small step that noticeably reduces how much water reaches your walls and floors.
Step 3: Contain and Protect
With the flow stopped, limit the damage in the area:
- Place a bucket under the leak to catch any remaining drips
- Use towels to soak up standing water and keep it from spreading toward walls and flooring
- Move furniture, electronics, and valuables away from the wet area
If water has pooled near outlets or the electrical panel, keep clear and turn off power to that area at the breaker if you can do so safely.
Watch for Water and Electricity
This is the one part of containing a leak where your safety matters more than your property. If water has reached outlets, light fixtures, or the electrical panel, do not step into it to reach anything. Turn off power to the affected area at the breaker only if you can do so without standing in water. If you cannot reach the breaker safely, stay clear and tell your plumber and, if needed, an electrician when they arrive.
Step 4: Assess and Photograph
Before cleanup, take photos and video of the leak and any damage. Your insurance provider will want documentation if you end up making a claim. Note when the leak started and what you have done so far, so you can pass that information to the plumber.
What Your Insurer Will Want to See
Clear documentation strengthens a claim. Capture the source of the leak if you can see it, the water on the floor, and any damage to walls, ceilings, flooring, or belongings before you start mopping up. Photograph affected items individually where you can. The goal is a record of the full extent of the damage as it was, since once you clean up, that evidence is gone.
Should You Try a Temporary Fix?
A temporary fix can slow a leak, but it is not a substitute for repair. Options like pipe repair tape, a pipe clamp, or a rubber patch secured with a hose clamp may reduce the drip until help arrives. Do not rely on any of these as a permanent solution. The pipe still needs to be properly repaired, and turning the water back on before that happens risks a bigger failure.
When It Is an Emergency
Some leaks cannot wait. Treat it as an emergency and call right away if:
- Water is spraying or flowing rather than dripping
- You cannot stop the water at any valve
- Water is near electrical outlets, fixtures, or the panel
- The leak is coming from inside a wall or ceiling
- Water is accumulating faster than you can contain it
