What Should You Do When You Find a Water Leak in Your Ontario CA Home?
Finding water where it shouldn't be has a way of changing your plans pretty quickly.
Maybe you open the cabinet under the kitchen sink and everything is wet.
Maybe water is dripping through the ceiling.
Or maybe you're walking through the house and step onto a section of carpet that definitely
wasn't wet yesterday.
Your first reaction is probably to figure out where the water is coming from.
Your second is usually, "How bad is this?"
The answer depends on the leak.
A loose connection underneath a sink is very different from a pipe leaking somewhere behind
a wall. Still, what you do during those first few minutes can make a big difference in how
much damage you're dealing with later.
If you find a water leak in your Ontario home, here's where we'd start.
First, Figure Out How Much Water You're Dealing With
Not every leak is an emergency.
If there's a slow drip underneath the bathroom sink and you can clearly see where it's coming
from, you have a very different situation than someone who has water spreading across the
floor.
Take a look around before doing anything else.
Is the water still coming out?
Is it getting worse?
Can you see where it's coming from?
Is it near an electrical outlet or appliance?
Those questions help determine what needs to happen next.
If water is actively spreading and you can't control it at the fixture, shutting off the home's
main water supply may be the safest move until a plumber can take a look.
It's also worth knowing where that shutoff is before you ever need it. Trying to find it for the
first time while water is running through the house isn't much fun.
If You Can Stop the Water at the Fixture, Do That
First
Sometimes you don't need to shut off water to the entire house.
Toilets, sinks, and certain appliances have their own shutoff valves. If the leak is clearly
coming from one of those fixtures and you can safely reach the valve, turning it off may stop
the problem while leaving water available everywhere else.
This is especially helpful when you're dealing with something obvious, such as a leaking toilet
supply line or a problem underneath the sink.
But don't force a valve that won't move.
Older shutoff valves can become stiff over time. Trying to muscle one closed can turn a
manageable leak into another plumbing problem.
If it doesn't move easily, leave it alone and move to the main shutoff instead.
Water Near Electricity Changes Things
This is where we'd rather see someone be overly cautious.
If water is coming through a ceiling near lights, running toward an outlet, or collecting around
electrical equipment, don't start reaching around trying to find the leak.
Water and electricity aren't a combination worth experimenting with.
Stay away from the affected area and get professional help.
The same goes for water around certain appliances or electrical panels. Stopping property
damage matters, but your safety matters more.
Once the Water Stops, Don't Assume the Problem Is
Over
This catches people sometimes.
The valve gets turned off.
The dripping stops.
You grab a few towels, clean everything up, and suddenly the situation doesn't feel nearly as
urgent.
But all you've really done is stop more water from coming out.
You haven't necessarily fixed what caused it.
A loose fitting may need to be repaired. A damaged supply line may need replacement. If the
leak started somewhere behind a wall or underneath the floor, there's still the question of
exactly where the pipe failed.
Stopping the water buys you time.
Finding the cause keeps it from happening again.
What If You Can't Find Where the Water Is Coming
From?
This is where things become a little more frustrating.
You can see the water.
You just can't find the leak.
Maybe there's a stain spreading across the ceiling, but the room above it looks completely
dry. Or the flooring near a wall is damp even though there isn't a sink, toilet, or appliance
anywhere nearby.
Water doesn't always take a straight path from the leaking pipe to the place where you
eventually see it.
It can follow framing or other surfaces before appearing somewhere else.
That's why the wettest spot isn't automatically the place where someone should start
opening a wall.
Professional leak detection can help narrow down the source before unnecessary work
begins.
Royalty Plumbing offers leak detection in Ontario and uses methods including pressure
testing and line tracking to help locate plumbing leaks.
Sometimes You Don't Find Water at All
Not every leak introduces itself with a puddle.
Some are much quieter.
The first sign might be a water bill that doesn't make sense.
Maybe the wall develops a stain.
Maybe there's a musty smell in one room that keeps returning.
Or your water meter continues showing usage even though nobody in the house is running
water.
Those situations are a little different because you aren't dealing with an obvious leak you can
shut off.
We covered those clues in more detail in our guide to How to Tell If You Have a Hidden Water
If several of those signs are showing up together, having the plumbing checked is usually
better than waiting for the leak to become visible.
Should You Clean Up the Water Yourself?
If it's a small amount of clean water and the area is safe, getting things dry is a good idea.
Towels can handle small spills. Depending on the situation, fans can help dry damp surfaces
after the source of the water has been stopped.
The situation changes when you're dealing with a large amount of water, contaminated
water, or water that has gotten into areas you can't easily dry.
And if the backup involves sewage, that's not something we'd recommend treating like an
ordinary spill.
Keep people and pets away from the affected area and call for professional help.
Take a Few Pictures Before Everything Gets Cleaned
Up
This takes about thirty seconds and can be surprisingly useful.
Take photos of where you found the water.
Photograph any visible damage.
If you can safely identify where the leak appears to be coming from, photograph that too.
Why?
Because once the water is shut off and everything starts drying, some of the clues disappear.
Those pictures may help your plumber understand what happened before they arrived. They
may also be useful if the leak caused enough damage that you need to speak with your
insurance company.
You don't need to turn the situation into a photo shoot.
A few clear pictures are enough.
What About a Leaking Water Heater?
Water around the water heater deserves its own mention because the source matters quite a
bit.
Sometimes the tank isn't actually leaking.
The problem could be a valve, fitting, or plumbing connection around the unit.
Other times, especially with an older water heater, the tank itself has begun to fail.
Those are two very different repairs.
If you're seeing water around the unit, our Why Is My Water Heater Leaking? article explains
some of the common places it can come from and when replacement may enter the
conversation.
When Does a Water Leak Become an Emergency?
This isn't always determined by the size of the leak.
A relatively small amount of water near electrical equipment deserves immediate attention.
So does a leak you can't stop.
Water coming through a ceiling, a burst pipe, rapidly spreading water, or sewage entering
the home are all situations where waiting until tomorrow may create a much larger problem.

If you've already shut off the water and everything is contained, you may have more
breathing room.
The important part is not ignoring the cause simply because you've managed to stop the
immediate mess.
Frequently Asked Questions
Should I shut off the water if I find a leak?
If water is actively leaking and you can't stop it using the shutoff for the affected fixture,
turning off the home's main water supply can prevent additional water damage while you
arrange for repairs.
Where is the main water shutoff in a house?
The location varies from home to home. If you aren't sure where yours is, it's worth locating it
before an emergency happens so you aren't searching for it while water is spreading.
Can I wait until tomorrow to call a plumber?
That depends on the leak. A contained drip is different from a burst pipe, water near
electricity, sewage, or a leak that's actively damaging the home. If you can't control the
water or aren't sure the situation is safe, don't wait.
What if I can see water damage but can't find the leak?
The source may be hidden behind a wall, underneath flooring, or somewhere else along the
plumbing line. Water can travel before becoming visible, which is why leak detection may be
needed to locate the actual source.
