The Burtons Auto Top-up system is designed to keep a constant water level in you pond.
When the water level of your pond drops below the low sensor the unit open the mains water solenoid letting water though to top up the pond. Once the water has reached the high level sensor the unit shuts the solenoid off again stopping the water flow.
With all ponds keeping a constant water level is important and more so for systems with a gravity fed drum filter. Our unit comes as standard with a 20mm water level differential but this can be easily adjusted if required.
