Abstract

A main water supply (1) is equipped with a main valve (2) followed by a first main pipe (3) running through a first check valve (4), and further to a first adapter (6) while a pilot pipe (7) runs from the main valve (2) through a secondary valve (9) and further a pilot coupling (16). A pressure pipe (12) runs to a secondary valve (9). From the first main pipe (3), a branch pipe (26) runs through a second check valve (28) to a water heater (27) and a second main pipe (29) runs to a second adapter (6.1) through a third check valve (30). A solenoid valve (17) is operated by a timer (18) or by the control signal of a household appliance. Pressure sensors (23, 33) signal of a household appliance. Pressure sensors (23, 33) signal to lamps (23, 34) on a panel(25).

Dependent claims

Method for controlling the supply of a fluid from a pressure system and for monitoring leakages characterized in that the supply of fluid of the pressure system is closed by a main valve (2) which:

a) opens for the fluid to a first main pipe (3) if
a pressure drop signal which produces by drop in the pressure in the first main pipe (3) when at least one valve is opened which are connected to the first main pipe (3) and at the same time
the pressure in the first main pipe (3) is registered to be higher than a threshold value when at least a valve is opened, and
b) closes for the fluid into the first main pipe (3) if
a pressure drop signal which produces when the pressure is dropping in the first main pipe (3) when at least one valve is opened which is connected to the first main pipe (3) and at the same time
the pressure in the first main pipe (3) is registered to be lower than a threshold value when at least one valve is opened.
