How it works?

Product Information

The system is build simple and reliable.

A pressure bulb pushes air into a tube that reaches all the way to the bottom of the cistern. The needle of the gauges correspondes with the depth of the water, as soon as bubbles come out of the nozzle at the bottom of the gauge. After pumping two or three times the needle reaches its maximum height. No matter how many times you pump, the pressure will not alter: You will just push more bubles out of the nozzle, but the reading remains the same.

Practically it means that you sqeeze the bulb two or three times until the needle doesn't go up any further. That's your readout. Simple and foolproof.

 

Since the installation is easy and fast, the first readout can often be obtained in matter of minutes
