water storage tank - Balmoral Group

Pipe connections and fittings
All pipe connections are made at Balmoral Tanks’ factory before
dispatch and customers are asked to provide full details when
ordering. The type of pipe connection should be specified together
with the relevant standard to which the coupling flanges are drilled
or the pipes screwed. To assist delivery, the size and position of
each connection should also be specified at the time of ordering.
Ball and gate valves and all pipework, including bends and flanges,
can be supplied if specified at the time of ordering.
Connections can be supplied as flanged stools to BS4504, ASA or
DIN standards, or, for small pipework, screwed sockets to BS1387.
The connections are shop-welded to the plates in positions agreed
at the time of order.
Pipework configuration
The inlet or delivery pipe can enter the tank through either the side
wall at the top of the tank or through the tank base. Flow can be
controlled through a ball valve, equilibrium float valve or automatic
float switch.
The outlet or service pipe should be taken through the base of the
tank and fitted with an internal bellmouth pipe or rose strainer to
prevent suspended matter entering the water supply.
The overflow should always be fitted to give at least 75mm of
freeboard below the top of the tank in accordance with the UK
Water Byelaws, or other regulations, to give the required air gap.
The washout pipe opening should be fitted flush with the bottom of
the tank and a sluice valve fitted immediately below the tank base.
