Installation
WARNING: Contaminated water
hazard.
Do not connect sea water flush toilet inlet
line to an onboard potable water system
in any way. This can cause contamination
of the potable water system. If fresh water
is desired, purchase the freshwater-flush
version of the toilet, or provide a separate
freshwater tank that supplies water only
to the toilet. Failure to obey this warning
could result in death or serious injury.
Be sure to install a vented loop that will
not prevent the required water flow to
the toilet when it is flushed. An electric
solenoid type is recommended.
6.3.1 Sea water flush models
1. Install the seacock and inlet water line (not
supplied).
– Use a 3/4 in. (19 mm) full-flow seacock
and a 3/4 in. (19 mm) ID flexible hose.
Follow the seacock manufacturer's
installation instructions.
– Make sure the inlet seacock is below
the sea water line at all times, during all
conditions of full heel.
– Make sure all inlet hose connections have
no sharp bends or restrictions.
– Use two stainless steel hose clamps at
each connection.
– Provide hose support every 3 ft
(0.9 m) along the inlet hose run to limit
movement.
– Keep hose runs as short as possible.
Eliminate sags or low spots that may
hinder flow.
2. Install the water inlet strainer (not supplied).
– A 100-mesh strainer is recommended
between the inlet seacock and the sea
water flush toilet.
3. Install the inlet check valve for above-
waterline installations (not supplied).
– A check valve should be installed in the
inlet supply line to ensure the toilet's
sea water pump stays primed between
flushes.
– The check valve should be located as
close as possible to the inlet seacock. See
"Above water line system" on page 7.
4. Install a vented loop (not supplied).

– If the toilet rim will ever be less than
8.0 in. (203 mm) above the highest
possible waterline at any point of heel,
trim or load, then a 3/4 in. (19 mm)
vented loop must be installed in the inlet
hose between the inlet seacock and the
toilet. See "Below water line system" on
page 8.
– The vented loop must be positioned
a minimum of 8.0 in. (203 mm) above
highest possible waterline during all
conditions of heel, trim or load.
6.3.5 Freshwater flush models
1. Install the inlet water line (not supplied).
– Use a 0.5 in. (13 mm) ID flexible hose with
1/2 in. NPT fitting connects to the toilet
water valve.
2. Install a shut-off valve in the inlet line (not
supplied).
– For toilet cleaning and maintenance.
6.4 Outlet plumbing
Sea water flush models only.
1. Install the seacock and outlet sanitation hose
(not supplied).
– Use a 1.0 in. (25 mm) or 1.5 in. (38 mm)
full-flow seacock and flexible hose
to route the waste to a holding tank
with a discharge pump, or route
directly overboard. Follow the seacock
manufacturer's instructions.
– Make sure the waste outlet seacock is
both aft and higher than the water inlet
seacock.
– Outlet plumbing should have no sharp
bends or restrictions.
– Use two stainless steel hose clamps at
each connection.
– Provide support along entire hose run
to limit movement and side-loading on
connections.
– Keep hose runs as short as possible.
Eliminate sags or low spots that may
hinder the flow.
2. Install the discharge hose loop near the toilet
(not supplied).
– To retain water in toilet bowl, make
a 12.0 in. (300 mm) high loop in the
discharge line as near to the toilet as
