Water Coming Through the Ceiling
Water coming through a ceiling is an active leak from a pipe, fixture, or drain above. This can sometimes indicate a burst or pinhole supply line, a leaking drain under a bathroom, a failed supply line to a toilet or sink, or a leaking shower pan. Shut off the water immediately to limit damage.
- —Burst or pinhole leak in a supply line above the ceiling
- —Leaking drain pipe from a bathroom above
- —Failed supply line to a toilet, sink, or washing machine
- —Leaking shower pan or tub drain
- —Corroded cast iron drain pipe (older homes)
Try This First
Safe, simple steps you can try yourself. If any step feels beyond your comfort level, skip it and continue below.
- 1
Shut off the water source safely
Use an accessible fixture shutoff if the leak is clearly isolated there; otherwise use the home's customer-side main shutoff if you know it and can operate it safely. If you cannot isolate an uncontrolled leak, contact the serving water utility rather than forcing or manipulating utility-owned meter equipment.
- 2
Keep clear of a bulging ceiling
Place containers only if you can do so without standing beneath a sagging or bulging ceiling. Do not puncture a water-loaded ceiling as a routine homeowner step — concealed electrical wiring and sudden collapse can create additional hazards.
- 3
Treat nearby electrical equipment as a separate hazard
Do not touch wet outlets, switches, fixtures, cords, or a wet breaker panel, and do not cross standing water to reach electrical equipment. If a completely dry electrical panel is safely accessible without entering the wet area and you know the correct breaker, power to the affected area may be shut off; otherwise leave electrical isolation to the utility or a qualified electrician.

Identify the source if possible
Is there a bathroom directly above? A washing machine on the floor above? The fixture above the leak is the first suspect. If it's a drain (only leaks when water runs), you may be able to stop using that fixture. If it's a supply line (leaks constantly), the main must stay off.
If the problem is resolved
If shutting off a specific fixture's supply valve stops the leak, you've isolated it — but the pipe or fixture still needs repair before you turn it back on.
If the problem persists
If the main water must stay off to stop the leak, you need a plumber. Do not turn the water back on until the leak is repaired. Continue below.
Stop and Call a Plumber If…
- Water is actively coming through the ceiling — shut off the main and call
- The ceiling is bulging or sagging with water weight
- Water is near electrical fixtures or wiring
- You can't find or turn the main shutoff valve
- The leak is from a drain that continues even with the main off (sewage)
- ✓Narrowing the source of the leak above the ceiling using fixture use patterns, visible conditions, moisture tracing, and access where needed
- ✓Determining if it's a supply line, drain, or fixture failure
- ✓Repairing or replacing the failed pipe or fixture
- ✓Checking for hidden damage in the ceiling and subfloor
- ✓Evaluating whether mold remediation is needed
