IMPORTANT INFORMATION
Professional installation
We recommend that our products are fitted
by a fully qualified professional plumber. They
should be installed correctly and in accordance
with all local water regulations and the system
protected by non-return valves (not supplied).
All products should be accessible for routine
servicing.
Supply temperature safety notice
A thermostatic mixing valve (TMV) should
be fitted (not supplied) to the hot supply to
restrict the temperature to a safe working/
maximum temperature to comply with local
building regulations, current legislation, relevant
standards and codes of practice. Maximum
allowed temperatures vary subject to type of
installation or specification of building.
Flushing system
It is most important to flush out all pipework
thoroughly before connecting the taps. This
is the single most common cause of ceramic
cartridge failure.
Supply connections
Lefroy brooks do not supply any pipework or
connections for taps as they can be installed
in a variety of configurations subject to each
customers installation design or requirement.
Water quality
In hard water areas, a suitable water treatment
system should be provided to prevent limescale
deposits (calcium deposits) which may eect
the long term performance of the ceramic
cartridge. Exterior surfaces should be gently
wiped with a dry soft cloth after use to minimise
water stains and limescale deposits.
General installation details
Basin models have ½" BSP threaded tails and are
designed to fit standard 15mm tap connectors.
Bath models have ¾" BSP threaded tails and are
designed to fit 22mm tap connectors. The white
sealing washer should be fitted to the underside
of the basin/bath/mounting surface, NOT
directly under the tap base.
Servicing
All serviceable parts are available to maintain
your Lefroy brooks product.

SERVICING – CARTRIDGE REPLACEMENT
Before continuing please ensure that the
water supplies have been isolated and drained
where necessary. Always support the spout
when removing/fitting handwheel/lever
assemblies or ceramic cartridges.
1 Unscrew and remove the handwheel/lever
assembly in a counterclockwise direction.
Wearing rubber gloves such as those used for
washing up will improve grip.
2 Unscrew and remove the ceramic cartridge
in a counterclockwise direction using a 17mm
spanner.
3 Fit a new ceramic cartridge. Turn the splined
end of the ceramic cartridge so that it is in the
‘o’ position.
4 Fit the handwheel/lever assembly ensuring
that the indice/graphics are correct.
