How to Fix a Humming Toilet

If you have heard a moaning, groaning, or humming noise when you flush your toilet, you are probably feeling annoyed and frustrated that you have been unable to locate the issue and fix the problem. In fact, it may take you a while to determine where the noise is coming from. You may think that it is coming from your pipes or a gremlin in the basement, but rest assured, the culprit is most likely your toilet.

This annoying noise coming from within your toilet tank is an indication that something is wrong. Consider it a warning that a more serious problem is lurking in your future if it is not taken care of immediately. Leaks, excessive water loss, damage to your floors and walls, and other major expensive problems may lie ahead.

No one wants to be faced with a leaking toilet. aquaHALT offers an easy-to-install system that not only detects water leaks but also shuts off the water source and sends an alert directly to you. Save yourself money, time, and headaches by installing an affordable solution with aquaHALT.

What Causes a Toilet to Hum?

There can be several sources of noise from your humming toilet, but perhaps the most common is inconsistent water pressure. Pressure exerted against the diaphragm in the fill valve can cause the issue. This can be adjusted through a pressure reducer valve located near the meter. Be sure to check the diaphragm for wear or weakness as well.

If the humming is more like a loud groan, check that all the washers are tight and the ballcock assembly is working as it should. If you think this is the problem, try opening the tank, lifting up on the float, and flushing. If the groan goes away, you may have found your problem: a loose washer. Locate the three screws at the top of the fill valve, Turn off the water, and flush to empty out the tank. By unscrewing the screws, you can remove the ball, armature, and the top of the flush valve. Take the washer out of the bottom of the valve and replace it with a new one.

If this does not solve your humming problem, you may need to replace the fill valve. Once you have replaced the fill valve, adjust the water level within an inch of the overflow tube. If you are still hearing the noise when you flush, it could be a vibration in your water supply lines.

If your water supply lines are vibrating, you will hear a noise as the toilet refills. This could lead to serious problems since the vibrations could result in splits in your lines and excessive water leaks.

In commercial facility management, the traditional approach to maintenance has been either
reactive (fixing things after they break) or preventive (fixing things on a fixed schedule).
Predictive Maintenance (PdM) represents a significant leap forward, utilizing real-time data
and analytics to anticipate equipment failure before it occurs. For commercial water
systems
, PdM, powered by water automation, is the key to minimizing downtime, reducing
costs, and ensuring continuous, reliable operation.

Predictive maintenance for water systems relies on the continuous stream of data generated
by an automated infrastructure. This data is analyzed by machine learning algorithms to
establish a “normal” operational baseline for every component.

The system constantly monitors critical KPIs that signal system health:

  • Flow Rate Consistency: Fluctuations in flow rate that do not correlate with usage patterns can indicate a blockage or a developing leak.
  • Pressure Trends: A gradual, unexplainable drop in pressure can signal a small, growing leak in the piping network.
  • Vibration and Temperature: For pumps and motors, abnormal vibration or temperature spikes can predict mechanical failure.

The core of PdM is the ability to detect anomalies. For example, if a pump typically runs for
15 minutes to fill a tank, but the system notices it is now running for 20 minutes to achieve
the same result, the algorithm flags a potential issue—such as a clog or a loss of efficiency—
allowing the facility manager to inspect and repair the pump before it burns out.

By only performing maintenance when it is truly needed, PdM ensures that components are
used for their full, optimal lifespan. This reduces the cost of unnecessary replacements and
the labor associated with fixed-schedule maintenance. Furthermore, by preventing
catastrophic failures, the system protects the lifespan of the entire water infrastructure.

The shift to predictive maintenance is essential for any commercial property aiming for
operational excellence. By leveraging the continuous monitoring and analytical power of
water automation, facility managers can move beyond the costly cycle of reaction and
prevention. They gain the ability to anticipate and mitigate risks, ensuring that their
commercial water systems operate reliably, efficiently, and cost-effectively for years to
come.

Modern commercial buildings are complex ecosystems managed by a Building
Management System (BMS)
, which centralizes control over HVAC, lighting, security, and
energy consumption. For a water automation system to deliver its full value, it must be
seamlessly integrated with the existing BMS. This smart building integration ensures that
water management is not an isolated function but a core, contributing element to the
building’s overall operational intelligence and efficiency.

Operating a water automation system independently of the BMS creates silos of data and
limits the potential for holistic optimization. Integrating water automation with BMS
provides several critical advantages:

Facility managers benefit from a single, unified dashboard where they can monitor all critical
building functions, including water usage and leak detection status. This eliminates the need
to switch between multiple platforms, streamlining workflows and accelerating response
times.

Integration allows the water system to trigger actions in other building systems, and vice
versa. For example:

  • Leak Event: Upon detection of a major leak, the water system can alert the BMS, which can then automatically shut down nearby electrical systems or notify security personnel.
  • Energy Optimization: The BMS can use water consumption data from the cooling tower to optimize HVAC scheduling, ensuring that water-intensive systems only run when necessary.

Combining water data with energy, temperature, and occupancy data within the BMS allows
for deeper, more sophisticated analysis. This holistic view is essential for predictive
maintenance
and identifying complex correlations, such as a spike in water usage coinciding
with a specific HVAC operational mode.

The method for smart building integration depends on the existing BMS infrastructure, but
typically involves one of the following protocols:

Integration
Protocol
DescriptionBest Use Case
BACnet/IPA standard communication protocol for building
automation and control networks.
Most common for modern
commercial BMS; allows for direct
data exchange between systems.
Modbus
TCP/IP
A widely used serial communications protocol.Ideal for integrating older or
simpler water automation devices
into a modern BMS.
API
Integration
Using a vendor’s Application Programming
Interface (API) to exchange data directly between
the cloud platforms of the water system and the
BMS.
Provides the most flexibility and
allows for the exchange of rich,
real-time data and control
commands.

When planning to integrate water automation with BMS, FMs should prioritize systems
that offer:

  • Open Architecture: The system should use open, non-proprietary protocols (like BACnet) to ensure compatibility with a wide range of existing and future BMS platforms.
  • Scalability: The integration should be able to handle the addition of more sensors and devices without requiring a complete system overhaul.
  • Cybersecurity: Since the water system is now connected to the building’s central network, robust security measures are essential to protect against unauthorized access.

For commercial properties striving for true operational excellence, integrating water
automation with the Building Management System
is a non-negotiable step. It transforms
water management from a standalone function into an intelligent, contributing part of the
smart building ecosystem. This seamless integration enhances efficiency, improves risk
mitigation, and provides facility managers with the unified control necessary to optimize the
entire property.

Consult with waterAUTOMATION to ensure your water automation solution achieves
seamless and secure smart building integration with your existing BMS.

The effectiveness of any commercial water leak detection system hinges on the quality and
strategic deployment of its sensors. With a variety of water sensor technology available,
facility managers must understand the differences to make an informed decision. Choosing
the right water leak sensor
for a specific application is critical for maximizing coverage,
minimizing false alarms, and ensuring rapid response to a leak event.

Water leak sensors can be broadly categorized based on what they detect: the presence of
water (spot/rope sensors) or an anomaly in the water flow (flow sensors).

These sensors are designed to detect the physical presence of water on a surface.

Sensor
Type
Detection MethodBest PlacementKey Benefit
Spot SensorUses two metal probes that
complete an electrical
circuit when bridged by

Under sinks, near water heaters,
under HVAC units, in drip pans,
and near floor drains.

A long, flexible cable that
detects water along its entire
length.
Wrapped around pipes, along the
perimeter of a room, or under
raised floors (e.g., in a data
center).
Excellent for covering
large areas or tracing
the path of a pipe.

These sensors are installed directly on the water supply line and monitor the movement of
water through the pipes.

Main water line, sub-
meters for specific zones
(e.g., cooling towers,
tenant floors).
Detects leaks within the pipe
system and monitors overall
consumption for billing and
waste analysis.

Even the most advanced sensor is useless if placed incorrectly. Effective best placement for
water leak detectors
requires a risk-based approach:

  • Near the Source: Place sensors directly at the point where a leak is most likely to originate. This includes under all water-using appliances (dishwashers, ice makers), near plumbing connections, and at the base of water heaters and boilers.
  • In the Path: In areas where water could travel, such as mechanical rooms or basements, use rope sensors to cover the floor perimeter or the path leading to a drain.
  • Near Critical Assets: In areas like server rooms, place sensors under raised floors and near cooling units to protect high-value equipment.
  • At the Entry Point: Install a flow sensor on the main water line to monitor the entire building’s consumption and detect large-scale leaks immediately.

The final consideration is how the sensor integrates into the overall water automation
system
. A smart sensor should not just detect water; it must communicate instantly with a
central hub that can:

  1. Alert: Send immediate notifications to the facility manager.
  2. Analyze: Differentiate between a small drip and a burst pipe.
  3. Actuate: Trigger an automatic water shut-off valve to stop the flow of water.

Choosing sensors that are compatible with a robust, cloud-based platform ensures that the
data collected is actionable and contributes to a comprehensive predictive maintenance
strategy.

Choosing the right water leak sensor is a critical investment in commercial property
protection. By understanding the different water sensor technology and implementing a
strategic placement guide, facility managers can create a layered defense that provides
continuous, reliable monitoring, ensuring that no leak, large or small, goes undetected.

Consult with waterAUTOMATION experts to determine the optimal sensor
technology and placement strategy for your commercial facility.

While the financial cost of water waste—inflated utility bills and damage repair—is
immediate and tangible, the environmental toll is often overlooked. For commercial
properties, every gallon of wasted water represents a significant drain on local resources and
contributes to a larger carbon footprint. Adopting a strategy for commercial water

conservation is therefore a dual imperative: it is essential for financial health and a non-
negotiable component of corporate sustainability initiatives.

Water waste in a commercial building is not just about the water itself; it is about the energy
and resources required to treat, pump, heat, and deliver that water.


The Incident: At 2:00 AM on a Tuesday, a supply line to a washing machine in a 25th-floor
unit failed catastrophically. Under normal circumstances, this failure would have resulted in a
continuous flow of high-pressure water, flooding the unit and cascading down through the
walls and ceilings of the 24 units below it.

  1. Energy Consumption

Water is an energy-intensive resource. Significant amounts of electricity are used for:

  • Pumping: Moving water from the source to the building and throughout the property.
  • Heating: Heating water for domestic use and HVAC systems.
  • Treatment: Treating wastewater before it is returned to the environment.


When water is wasted through leaks or inefficient systems, the energy used to process and
deliver that water is also wasted, directly increasing the building’s carbon footprint.

2. Strain on Local Water Resources

In many regions, water scarcity is a growing concern. Commercial properties that waste
water place an unnecessary strain on local reservoirs, aquifers, and municipal water supplies.
This impacts the community and the environment, particularly during periods of drought or
high demand.

3. Wastewater Treatment Burden

Every gallon of water that enters a building must eventually be treated as wastewater.
Excessive water use from leaks or inefficient systems overloads municipal wastewater
treatment plants, requiring more chemicals, energy, and infrastructure capacity to process.

Automated water systems are the most effective tool for addressing the environmental
impact of water waste
by providing the data and control necessary for true conservation.

The decision to implement automated water conservation strategies extends far beyond
the water bill
. It is a commitment to reducing energy consumption, preserving local water
resources, and minimizing the environmental footprint of the commercial property. By
leveraging the power of automation, facility managers can transform their buildings into
models of efficiency, aligning financial success with environmental stewardship.
