Water leaks can lead to substantial damage to property and belongings, resulting in costly repairs and replacements. This article delves into the automation of leak detection, featuring solutions from Danfoss Climate Solutions. By utilizing Danfoss’s innovative eco brass solenoid valves, which are safe for potable water and straightforward to install, you can effectively prevent water leaks.

Water leaks often stem from aging or damaged pipes and fittings, improper installations, water hammer, or even freezing conditions that can cause pipes to burst. Initially, these leaks may go unnoticed until they form puddles, potentially damaging ceilings, walls, wooden floors, and electronic devices. Mold growth and expensive repairs may follow. In apartment buildings, a single leak can impact all units below.
Traditionally, leak detection depends on someone noticing the leak and manually shutting off the water supply. To automate this process and safeguard property and assets, two components are essential: a method to detect the leak and a mechanism to cut off the water supply.
There are two primary approaches to detecting water leaks: data comparison using a flow meter and physical detection with a sensor. By measuring the flow rate through a pipe and comparing it to historical patterns, potential leaks can be identified. This method can be applied to an entire home or specific appliances, such as washing machines.
For instance, in a single toilet, the flow rate should be zero most of the time, except during flushing. If a leak exists, the flow rate will not be zero; instead, there will be a small but constant minimum flow rate.
Manual leak detection can be performed by checking a water meter, recording and comparing consumption values over time, or observing the small dial on a mechanical meter. The two most common methods for measuring water flow are mechanical and ultrasonic flow meters.
Mechanical flow meters utilize a small internal impeller or paddle wheel that rotates as water flows through it. The meter measures the rotational speed of the impeller, and the volume of water flowing is proportional to this speed. A sensor detects the movement and generates electrical pulses, which are used to calculate the flow rate.
Ultrasonic flow meters can be clamped onto existing pipes. They emit two ultrasonic signals: one travels downstream with the water, and the other travels upstream against it. When water flows, the downstream signal travels faster than the upstream signal. By measuring the time difference, the velocity of the water can be determined, allowing for the calculation of the flow rate.
To detect the presence of water, a simple probe sensor with two stainless steel probes at floor level can be used. When water passes between the probes, it completes a circuit, allowing a small electrical current to flow. Other versions may have conductive tracks that complete a circuit when water flows over them.
The signal from these sensors is sent to a controller, which activates an alarm and sends a signal to the solenoid valve to shut off the water supply. Another common method is a leak detection cable, which uses conductive wires that trigger an alarm when water contacts them.
To automatically stop a leak, a solenoid valve, a controller, and a sensor are required. When the water sensor detects moisture, it completes the circuit, energizing a relay that closes the solenoid valve and shuts off the water supply.
The solenoid valve consists of an inlet and outlet for water flow, a diaphragm, and a piston held by a spring. When current passes through the solenoid, it creates a magnetic field that pulls the piston down, closing the valve.

Water leaks can cause significant damage to property and belongings, leading to expensive repairs and replacements. In this video, we will explore how to automate leak detection, sponsored by Danfoss Climate Solutions. You can prevent water leaks by using Danfoss’s new eco brass solenoid valves for leak detection, which are safe for drinking water and easy to install. Check the link in the video description for more information and specifications.
Water leaks often occur due to old or damaged pipes and fittings, poorly installed systems, water hammer, or even frost, which can cause pipes to burst. Initially, leaks can be difficult to detect until puddles form, leading to potential damage to ceilings, walls, and wooden floors, as well as destruction of electronic goods. Mold can develop, and costly repairs may be necessary. In an apartment building, a leak can affect all properties below.
Currently, leak detection relies on someone noticing a leak and manually shutting off the water supply. To automate this process and protect property and assets, we need two components: a method to detect the leak and a way to cut off the water supply.
