Waking up to no water in your apartment can be stressful, especially in Zurich where reliable utilities are expected. Whether it affects your entire apartment or just certain fixtures, understanding the cause and knowing the right steps to take can save you time and money.
This guide walks you through common reasons for water outages, what you can safely check yourself, and how Casafix can help you get your water supply restored quickly.
Common Reasons for Sudden Water Loss
Water Supply Interruption from the City
Zurich's water provider occasionally performs maintenance or repairs on municipal water lines. You'll typically receive a notice beforehand, but interruptions can sometimes occur unexpectedly.
Check: Contact your building manager or Zurich's water authority (ZWV) to confirm if there's a planned outage in your area.
Frozen Pipes
During cold Zurich winters, water pipes can freeze, especially in unheated areas like basements, exterior walls, or poorly insulated sections.
Signs: No water during freezing weather, pipes feel cold to the touch, or you see frost on exposed pipes.
Main Water Line Break
A rupture or damage to your apartment's main water supply line can completely cut off water flow to your home.
Signs: Wet spots on walls, unusually high water bills before the outage, or visible water damage in utility areas.
Closed or Stuck Water Shutoff Valve
Your apartment's main shutoff valve may have been accidentally closed or may be stuck in the off position.
Location: Usually found near your water meter or where the main line enters your apartment.
Water Meter Problems
A faulty or blocked water meter can restrict or stop water flow to your apartment entirely.
Note: Water meters are often located in shared building areas and require professional inspection.
Air in the Pipes
After maintenance work or water pressure fluctuations, air can become trapped in your pipes, preventing water flow.
Duration: This typically resolves itself within a few minutes to an hour as air releases.
What You Can Safely Check Yourself
Before calling a professional, try these safe diagnostic steps:
Check if it's a building-wide issue
Ask neighbors if they have water. If only your apartment is affected, the problem is likely internal. If multiple units are down, contact your building management.
Test all faucets and fixtures
Turn on faucets in your kitchen, bathroom, and other fixtures. Does any water come out? Is the pressure low? This helps identify if the problem is isolated to specific areas.
Locate your main shutoff valve
Find your main water shutoff valve (usually near the entrance point of water to your apartment or by the water meter). Ensure it's fully open (handle should be parallel to the pipe). You can gently try to open it if it appears closed, but don't force it.
Look for visible leaks
Check under sinks, around pipes, and in basement or utility areas for signs of water damage, leaks, or puddles. Note any wet spots or unusual moisture.
Wait a few minutes
Sometimes water returns after a few minutes, especially if air was trapped in pipes or temporary pressure fluctuations occurred. Wait and try again.
Important: Do not attempt to force any valves, disassemble pipes, or make repairs yourself. Even small mistakes can cause significant water damage or safety hazards.
When to Call a Professional Plumber in Zurich
Contact a professional plumber immediately if:
- Water remains off after waiting and checking the shutoff valve
- You see visible leaks, wet spots, or water damage in your apartment
- Only hot water is affected (could indicate a water heater issue)
- Water pressure is extremely low despite the valve being open
- You notice water flowing from external pipes or in shared building areas
- You hear unusual sounds (banging, hissing) from pipes
- The problem affects multiple apartments in your building
- It's after-hours and you need emergency assistance (frozen pipes, burst lines)

Frequently Asked Questions
What's the difference between a water shutoff valve and a water meter?
The shutoff valve controls water flow to your apartment and can be opened or closed as needed. The water meter measures consumption. Both are important, but only the valve should be adjusted by tenants.
Can frozen pipes thaw on their own?
Sometimes, as temperatures rise. However, never use an open flame or extreme heat to thaw pipes, as this risks fire or pipe damage. Call a professional if water doesn't return as weather warms.
Is my landlord responsible for plumbing repairs in a rental apartment?
Generally, yes. Landlords are responsible for maintaining essential services including water supply. Document the issue and notify your landlord immediately. In emergencies, you may arrange repairs and deduct costs from rent (follow Swiss rental law guidelines).
How long does a typical plumbing diagnosis take?
Most diagnostics take 30 minutes to 1 hour. Complex issues may take longer, but our plumbers will communicate timelines upfront.
What should I do while waiting for the plumber?
Close your main shutoff valve to prevent additional water damage if a leak is suspected. Take photos of any visible damage for insurance purposes. Keep the area accessible for the plumber to work.
