Water leaks in hotels can occur in many locations and may be difficult to detect without a structured investigation process. When abnormal water consumption or leak alarms are detected, engineering teams should follow a systematic inspection approach to identify the source of the problem.

A structured investigation helps reduce water losses, prevent property damage, and restore normal system operation as quickly as possible.

Initial Verification of a Leak

Before starting a full inspection, it is important to confirm that abnormal water consumption is actually occurring.

Initial verification steps include:

• Review the main water meter readings
• Check water monitoring dashboards or Smartvatten alerts
• Review water consumption during low-demand periods
• Compare current consumption with historical patterns

If abnormal flow or continuous water consumption is confirmed, further investigation should begin.

Check for Continuous Flow

Continuous water flow during periods of low occupancy can indicate a possible leak.

Engineering teams should check whether water consumption continues during times when demand should normally be low, such as:

• Late night hours
• Early morning periods
• Periods of low occupancy

If water flow does not return to near zero during these periods, a leak may be present somewhere in the system.

Inspect Guest Rooms

Guest rooms are one of the most common locations for water leaks.

Typical issues include:

• Leaking toilet cisterns
• Dripping faucets
• Faulty shower mixing valves
• Damaged plumbing connections
• Toilets that continue to refill

Even small leaks in individual guest rooms can cause significant water losses if they occur continuously.

Inspect Public Restrooms

Public restroom fixtures may also develop leaks due to heavy usage.

Inspection points include:

• Toilets and flush mechanisms
• Urinals and flush valves
• Faucets and mixing valves
• Sensor-operated fixtures

These areas should be inspected regularly as part of routine maintenance.

Inspect Kitchens and Restaurants

Food and beverage operations use large amounts of water and contain several potential leak sources.

Inspection areas include:

• Dishwashers
• Ice machines
• Food preparation sinks
• Water supply connections
• Water filtration systems

Leaks in kitchen areas may sometimes remain hidden behind equipment or under counters.

Inspect Laundry Operations

Hotel laundry systems are another major water consumer and can be a source of leaks.

Inspection points include:

• Washing machines
• Water supply hoses
• Drain pipes
• Steam or hot water connections

Laundry equipment connections should be inspected regularly for wear or damage.

Inspect Mechanical Rooms

Mechanical rooms often contain several water systems and should always be inspected when investigating leaks.

Key inspection points include:

• Domestic hot water systems
• Water pumps
• Expansion tanks
• Pressure valves
• Pipe connections and joints

Mechanical room leaks can sometimes be detected through visible water, corrosion, or abnormal humidity.

Inspect Cooling Towers

Cooling towers can consume large volumes of water and may also develop leaks.

Inspection areas include:

• Cooling tower basins
• Make-up water valves
• Overflow pipes
• Blowdown systems
• Pipe connections

Incorrect cooling tower settings may also lead to excessive water consumption that may resemble a leak.

Inspect Irrigation Systems

Irrigation systems may develop leaks due to damaged pipes, broken sprinkler heads, or faulty valves.

Inspection steps include:

• Check irrigation zones for wet areas
• Inspect sprinkler heads
• Check irrigation valves and pipes
• Verify irrigation scheduling settings

Leaks in irrigation systems are sometimes difficult to detect because they may occur underground.

Use Submetering to Isolate the Leak

If the hotel has submetering installed, engineers can use subsystem water meters to narrow down the location of the leak.

Typical subsystem meters may include:

• Guest room water meters
• Laundry water meters
• Kitchen water meters
• Cooling tower make-up water meters
• Irrigation system meters

Comparing subsystem meters with the main water meter can help identify where abnormal consumption is occurring.

Confirm and Repair the Leak

Once the leak has been identified, corrective action should be taken immediately.

Typical repair actions may include:

• Replacing faulty valves
• Repairing damaged pipes
• Replacing worn seals
• Adjusting equipment settings
• Repairing irrigation systems

After the repair is completed, water consumption should be monitored to confirm that the issue has been resolved.

Preventing Future Leaks

Preventive maintenance helps reduce the risk of future leaks.

Recommended practices include:

• Routine plumbing inspections
• Regular monitoring of water consumption data
• Maintenance of valves and seals
• Inspection of irrigation systems
• Monitoring of Smartvatten or water monitoring alarms

Regular monitoring and preventive maintenance help hotels detect leaks earlier and maintain efficient water management.
