The question to ask first
The real test is not how alarming the problem looks but whether you can make it safe yourself. If closing a valve stops the water, and nothing involves gas, sewage in living space or wet electrical equipment, the repair can usually wait for a regular appointment.
That makes the shutoff valves the deciding factor. Owners who know where every stop and the main are can turn many late-night emergencies into next-day repairs.

Common questions
Is a leaking water heater an emergency?
If you can close the cold inlet and turn off the burner, it can usually wait until the next day. Water you cannot stop is the emergency.
What if I cannot find the main shutoff?
Check near the front hose bib and the meter box at the curb. If you still cannot stop the water, call for help now.
Should I call my insurer at night?
Most insurers have claim lines. Stop the water and document the damage first; call when you can.
