Overflow pools bring a remarkable visual effect to gardens! Their view over the garden, as beautiful as it is, is also very difficult to manage. Indeed, the regulation of the water level is an essential element for these swimming pools. To do this, we propose you today to discover the different solutions and the way in which an automatic level regulator works.
Overflow pool and buffer tank
Overflow pools are always accompanied by a connected buffer tank. This buffer tank will be essential for the regulation of the water level (and thus obtain this desired visual effect). This buffer tank can hold up to 10% of the total pool volume and is where the level sensors will be installed.
The buffer tank collects the water that is discharged from the pool via the overflow and then sends the water into the filtration circuit. It can be installed next to your main pool (and used as a paddling pool for example) or all around your pool under wooden beaches.
How does a level switch work?
To manage the water level and overflow, you can opt for an automatic regulator that will manage the level present in the basin. The level regulator consists of a control box, level sensors and accessories such as remote controlled water valve and strainer.
The level sensors are installed in the buffer tank and consist of different “levels” of detection. When a level sensor is crossed, the box interprets the information and thus adapts the level.
The functions of the level controllers
-If the “overfill” sensor is crossed, the cabinet starts a drain of the pool allowing water to be emptied until reaching the optimal water level sensors.
-If the “water shortage” sensor is above the water level, the cabinet starts the solenoid valve (connected to your water source) which adds water to your pool until the correct level sensors are reached.
-In both cases, in order to protect the filter pump, the regulator can choose to stop or force the filtration.
The different level sensors
In addition to the enclosure, each controller is available with different level sensors. You can choose to position a channel with 4 levels or independent probes at different levels in the buffer tank.
The advantages in use
Automatic level regulators protect the filter pumps by preventing them from operating when the level is too high or too low. They are also a way to reduce your total year-round water bill by optimizing your pool’s water level.
Now, if you were hesitating to build an overflow pool, you’d know how to manage it!
