Inlet plumbing requirements
For sea water flush models:
1. Seacock and inlet water line (not supplied with toilet):
a. 3/4 in. (19 mm) full-flow seacock and 3/4 in. (19 mm) ID flexible hose. Follow seacock
manufacturer's installation instructions.
b. Make sure inlet seacock is below sea water line at all times, during all conditions of full heel.
c. Make sure all inlet hose connections have no sharp bends or restrictions.
d. Use two stainless steel hose clamps at each connection.
e. Provide hose support every 3 ft. (0.9 m) along inlet hose run to limit movement.
f. Keep hose runs as short as possible. Eliminate sags or low spots that may hinder flow.
2. Water inlet strainer (not supplied with toilet)
a. 100-mesh strainer is recommended between inlet seacock and sea water flush toilet.
3. Inlet check valve for above-waterline installations (not supplied with toilet):
a. A check valve should be installed in inlet supply line to assure toilet's sea water pump stays
primed between flushes.
b. Check valve should be located as close as possible to the inlet seacock (
4. Vented loop (not supplied with toilet):
a. If the toilet rim will ever be less than 8 in. (20 cm) 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 (
b. Vented loop must be positioned a minimum of 8 in. (20 cm) above highest possible waterline
during all conditions of heel, trim or load.
Note
Be sure to install a vented loop that will not prevent required water flow to toilet
when toilet is being flushed. An electric solenoid type is recommended.
Warning!
Do not connect sea water flush toilet inlet line to a pressurized freshwater system.
This will result in a continuously running freshwater pump, which can possibly over-
flow the toilet bowl, flood the boat, and cause potential loss of property or life.
Warning!
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.
For freshwater flush models:
1. Inlet water line (not supplied with toilet):
a. 0.5 in. (13 mm) ID flexible hose with 1/2 in. NPT fitting connects to toilet water valve.
2. Shut-off valve in inlet line (not supplied with toilet):
a. For toilet cleaning and maintenance.
