Water Systems

The water pressure system is operated by a belt-driven, automatic diaphragm pump, controlled by a built-in pressure switch which turns the pump on when the pressure is lower than 1.5 kPa/cm² and off at 2.2 kPa/cm².

If the pressure of the water system fails, when the “fresh water” knob on the control panel is pulled out, it is possibly due to the pressure switch. A light tap on the red or black switch housing may help, but if not, the switch has to be replaced.

Pipes and Hoses

Filling, vent, and water pipes are made of PVC plastics. The tightness of the hose clamps at joints and fittings should be checked regularly. Leaks can be noticed if the pressure pump runs 1-2 seconds after intervals even when water is not used.

Junkers Gas Operated Water Heater (Type W 125)

  • Check that the “fresh water” switch is on.
  • Open the gas valve on the gas bottle.
  • Check that the gas valve under the sink is open.
  • Turn the water control counterclockwise to expel possible air.
  • Push the flame regulator to the “two-flame” slot and push it for 20-30 seconds.
  • Push the right-hand firing knob in until the pilot light is lit. Keep the knob in for 10 seconds.
  • Once the pilot light is on, push the flame regulator all the way to the right.

Caution: If the air is not properly expelled from the fresh water system, it may overheat the heater and possibly start a fire. Always ensure proper water pressure.

Raritan Water Heater

The NAUTICAT may be equipped with an optional Raritan water heater, an insulated 25-liter container that uses engine-cooled water for heating. The temperature is controlled by a thermostat, and the heater requires no operation after installation.

Hand Shower & Salt Water Pump

Hand Shower

An optional hand shower can be fitted in the forward or aft toilet. It has a 1.4-meter hose and a switch on the handle to toggle water flow from the faucet to the shower. The water runs through a hose to the bilge pump for disposal.

Salt Water Pump

A salt water pressure system, mechanical or electrical, can be installed as an option. The pump starts and stops automatically in the same way as the fresh water system. The outlets can be chosen for the galley, forward deck, and aft deck.

Water Gauge

The optional water gauge is fitted in one of the lockers of the galley. It works only when the ignition key is turned on.
