4.6 Pressure Tank Outlet
The RainsaverMK4E is supplied with an additional outlet specifically designed for the installation of a
pressure tank.
The installation of a pressure tank will:
-
Reduce wear and tear on your pump by significantly reducing the number of starts
-
Reduce your electricity consumption by significantly reducing the number of starts
Reduce the incidence of "pressure drop" when opening a tap
-
-
Stop your pump kicking in every time you open a tap or because of a small leak, like a
dripping tap, or toilet cistern.
To install a WATERMARK approved pressure tank:
-
Turn off both mains water supply pressure and your rainwater tank pump and supply
-
Open a tap to remove all pressure from the system
Using the spanner supplied, remove the ¾" plug from the "AUX. OUTLET" port. Note that
-
there is an o-ring inside the body of the Rainsaver which can be left in place if using a ¾"
BSP fitting, or removed if using a ¾" BSPT fitting.
Use a suitable flexible reinforced hose with ¾" BSP or BSPT MALE THREAD to connect
-
a WATERMARK approved pressure tank such as a GWS Energy Saver to your
RainsaverMK4E.
-
Carefully follow the manufacturer's instructions regarding pressurization of your
pressure tank.
4.7 Pressure Tank Pre-charge.
To ensure optimum performance and system life, the Pressure Tank pre-charge needs to be set by
filling the pressure tank with air through the air valve so that the air pressure is 65% of the pump
maximum pressure.
Pre-charge the pressure tank before it is installed by using an air pump or using the local service
station facilities.
