If you suddenly have no water anywhere in your house, the problem could be inside your plumbing system, at the water service or outside your property altogether.
Before assuming you have a broken water line, check how widespread the problem is.
A few simple observations can help determine whether the problem affects one fixture, your entire home or neighbouring properties as well.
Check More Than One Fixture
Start by trying several fixtures.
If one faucet has no water but other sinks, showers and toilets work normally, the problem is probably localized.
If there is no water at any fixture, the issue affects a larger part of the water supply.
Check both hot and cold water where appropriate.
Check Whether Your Neighbours Have Water
If the entire house has lost water, find out whether nearby properties are experiencing the same thing.
If several homes are affected, there may be an interruption to the public water system or work taking place nearby.
If neighbouring homes have normal water service but yours does not, the problem may be specific to your property.
Check Your Main Water Shut-Off Valve
If work was recently performed in the home, confirm that the main shut-off valve was not left closed.
Do not force a valve that appears seized, damaged or difficult to operate.
A valve that is only partly open can also affect water flow, although other problems can produce similar symptoms.
Was There Plumbing Work Recently?
Think about what changed before the water stopped.
Recent repairs, renovations, fixture work or work around the water service may provide useful information.
Tell your plumber about any recent work because it can help narrow down the cause.
Could a Broken Water Line Cause No Water?
Potentially.
A major problem with the water service can affect the amount of water reaching the house. However, complete loss of water does not automatically mean the underground line is broken.
That is why checking whether the issue is isolated to your property is useful before assuming excavation or major repair is required.
What About Low Water Pressure?
Very low pressure and no water are not necessarily the same problem.
A partially restricted supply, valve issue, leak or other plumbing condition may reduce pressure without stopping the water completely.
If you still have water but the flow has become noticeably weaker, the problem should be diagnosed based on those symptoms.
When Does No Water Become an Urgent Plumbing Problem?
If the public supply appears normal, your main valve should be open and your entire home still has no water, professional diagnosis may be appropriate.
Water is an essential service for toilets, washing, cooking and normal household use, so an unexplained complete loss of water should not simply be ignored.
If the problem involves an active water leak at the same time, controlling the leak takes priority.
What If Your Water Heater Was the First Problem?
If the issue began with water leaking around your water heater rather than complete loss of the cold-water supply, see what to do if your water heater is leaking.

FAQs
Possible causes range from a localized plumbing or valve problem to an issue with the property’s water service or a broader public water interruption.
If other fixtures work normally, the problem is more likely to be localized to that fixture or its supply rather than the entire house.
If multiple nearby properties are affected, first determine whether there is a broader water-service interruption.
Yes. A closed main water shut-off valve can stop the home’s water supply.
No. A water-line problem is one possibility, but there are other causes that should be ruled out before reaching that conclusion.
