SLAVE TANK
Where the installation requires additional cold water storage, a slave tank can be connected to the Home Booster to provide an
additional 180 litres of storage. The slave tank should be mounted on the same level as the Home Booster. A 2” BSP female
connection is provided on the rear of the Home Booster and slave tank for inter-connection of the tanks. When the slave tank is
used the mains water supply should be connected to the slave tank to ensure a good exchange of the water within the tanks.
Where floor space is limited, the slave tank can be located above the home booster on a platform, adequate clearance must be left
above the Home Booster for access to the cover screws. In this arrangement the mains fills the upper slave tank, and the slave tank
then fills the Home Booster by a 15mm pipe from the 2” BSP connection to the mains water connection on the Home Booster. In this
arrangement, the capacity of the slave tank is not available immediately as it must fill the Home Booster tank first. This arrangement
can be of benefit where the mains water supply is poor at refilling the storage tank. Ensure that the support base is able to support
the combined weight of the Home Booster and slave tank.
BYPASS
In the event of a failure of the Home Booster, it is recommended to install a cold water mains water bypass, to allow continued water
supply albeit at a reduced pressure to the installation.
The bypass arrangement must be installed strictly in accordance with the Water Byelaws Regulations. To prevent
stagnation, the water in the bypass should be left drained when the bypass is not in use. The diagram below is for
guidance only.
