While the air is being pumped, the water booster must be disconnected from the water
in the installation and any water remained in the water booster must be drained.
Otherwise, the static water pressure of the building will cause additional pressure in
the tank and the correct adjustment will not be made. A compressor or pedal air pump
can be used to pump air.
Caution:
It is inconvenient to use tanks (galvanized tanks) where air and water are in direct
contact as water booster tanks. Because in such tanks, the air in the tank dissolves in
the water and continuously leaks from the tank with the water. In the motopump
assembly, there is no air suction device to reinforce this decreasing air. Therefore, the
motor-pump does not reinforce the decreasing air in the tank. The air ends after a
while. The tank is completely filled with water and becomes unable to function. The
number of switch of the motors increases excessively.
Caution:
The pressure of the air in the membrane tank should be checked periodically (every
month, etc.). The air reduces by diffusion through the rubber membrane inside the MT
into continuous water or by leaking in the flange and valve connections. If the air
pressure drops in the tank, the number of switches of the water booster increases.
Therefore, fluctuation in sound and water increases.
