Gravity System
The drawing shows a typical installation of a shower valve on a gravity supplied system.
Please note the minimum head pressure required to ensure correct operation of the valve. In
accordance with good plumbing practice, we recommend that a totally independent hot and
cold water supply be taken to the valve.
The cold water supply must be connected
directly to the water cistern. The hot water
supply should be connected to the hot water
cylinder via an Essex flange or Sussex flange or
to the vent or a draw off pipe as close as
possible to the top of the cylinder.
For equal tank fed pressures there is no need to
fit the flow regulators. This installation is the
recommended minimum for gravity supplies.
For systems with less than 2 metre head
pressure, we recommend that a suitable booster
pump is fitted to increase the supply pressure.
Cold Mains & Gravity Hot Supplies
If the cold supply to the shower is direct from the
cold water mains and the hot water supply is
gravity fed from the cold water cistern via the
hot water cistern you MUST fit a pressure
reducing valve or a 6 l/min flow regulator.
