LK CubicSecure is a water safety system that pro-

tects against leakage by continuously measuring 

water consumption, water pressure and tempera-

ture. The unit emits alarms for both micro-leaks 

and larger leaks. When the water safety system 

detects a leak, it automatically shuts off the water 

flow.

System description

LK CubicSecure is a small unit that is easy to 

install in confined spaces. The unit is easily in-

stalled on incoming water pipes for a house or 

apartment. The water safety system is equipped 

with a switch for manual shut-off in the event of 

power failure or emergency.

NOTE!

Two water safety systems can be paired in 

order to avoid scalding in apartments. Pairing 

provides a synchronised automatic shut-off 

between the hot and cold water pipes. 

With the LK app and Wi-Fi connectivity, you can 

remotely control the unit to shut the water off or 

on, acknowledge alarms and monitor your water 

consumption, for example.
