The Lavac
Congratulations on the purchase of a Lavac
marine toilet. Lavac marine toilets are firm
favourites with sailors throughout the world,
providing their owner with a long and trou-
ble free working life.
The Lavac is one of the most simple to
operate marine toilets available. After use,
the seat and lid are closed and the pump is
then operated for 14-16 strokes (For full
instructions see page 21). As waste is
pumped out, the bowl is sealed causing a
vacuum which draws in the flushing water.
It’s as simple as that!
Within this handbook you will find informa-
tion and practical help on installing, running
and maintaining your Lavac. If you require
any further help or advice, please contact
us either by:
Telephone: +44 (0)1489 580580
Fax: +44 (0)1489 580581

Over many years we have taken advice from
sailors around the world concerning their
requirements for marine equipment and our
current range is a result of this ongoing com-
mitment. If you have any comments or help-
ful hints that you would like to share with us,
we would be very pleased to hear from you.
Installation kit provided with your lavac
All Lavac marine toilets are provided wit the
following parts for installation.
zPump – Hand (T/A: On Bulkhead; U/D:
Behind Bulkhead) or Electric (12 volt DC
or 24 volt DC, including wiring loom, time
switch, fuse and fuse holder)
zPlastic Bleed Plugs (Spares No.
TLZ9251)
zSelf adhesive operating instructions
zOwners Handbook.
Because the nature of an installation varies
from owner to owner, certain components
are easier to source locally. We therefore
feel it is best for you to purchase the follow-
ing separately, depending on your require-
ments.
z4 x 6mm (¼“) diameter Stainless Steel
securing bolts or screws for base
z4 x 6mm (¼“) diameter Stainless Steel

The Lavac System
General
The well known Lavac system is unique
and probably the only single action, above
or below water line, marine WC.
The Lavac has a china pan and is available
as either hand or electrically operated. On
the electric models 12 or 24V DC can be
supplied.
To flush simply close the lid and operate a
single pump. Pressure is reduced in the
bowl as waste goes out and flushing water
is drawn in. A small air bleed valve in the
inlet pipe prevents siphoning.
The particularly hygienic operation and
quietness are characteristics which in
themselves make Lavac a popular choice
for discerning owners. Simplicity of opera-
tion, robustness and reliability are further
important features.
By using a diverter valve the Lavac’s pump
can also be used for other pumping opera-
tions, such as shower tray discharge, bilge
pumping or discharge of the holding tank
(see page 20).
Because legislation is now prohibiting over-
board discharge from toilets, or at least
making it impractical, this edition of the
Lavac owners handbook now gives guid-
ance on holding tanks (see pages 18).
Features
zEasy and versatile in installation.
zCan be mounted under bunk or locker
and pulled out for use.
zPump, separate from bowl, can be
mounted in most convenient position
(above bowl consistent with instructions).
For installation behind bulkhead, a spe-
cial hand pump option is available (see
illustration on p.9).
zParticularly quiet and hygienic in opera-
tion.
zPump can also empty holding tanks, be
used as a bilge pump and/or shower
tray discharge pump.
zAny type of paper can be used,
although tissue is recommended.
zVirtually no maintenance.
zQuick release pump cover for easy
access.
zSingle action operation.
zExceptionally sturdy and durable.
zFull flow valve system.
zLow water usage.
zRemote holding tank installation (if cho-
sen).
zA water seal is the only certain and
complete way of preventing odour from
the waste pipe and/or holding tank.
Electric – Extra Features
zOnly marine toilet to offer manual back-
up with electric version
(see page 17).
zExtremely quiet in operation.
zFully marinised, automatic, adjustable
time switch
