Water System
General
The water system is very similar to a normal domestic water system. The system uses a fresh water storage tank
and the water is pumped via a filter to the various outlets. The water pump, when switched on, will maintain the
water pressure automatically to a pre-set pressure.
Hot Water System
The water can be heated in two ways, either using the engine or the electric water heater. The first uses the engine
coolant, which is pumped around the clarifier’s integral heat exchanger. Water heats more quickly when cruising
than when moored, this is due to the extra heat generated when the engines are put under load. The second way
water can be heated is using the domestic type water immersion heater that is fitted into the clarifier. The heater is
thermostatically controlled to maintain the water temperature. For safety reasons, there is a circuit breaker mounted
on top of the immersion heater that will trip if the water starts to get too hot. The water pump switch can be left in
the “on” position when moored but it is advised that you turn it off when underway.
Water Tank and Pump
The water tank vents are located below the water tank filler and should be periodically checked as the fine mesh
inside the mouth of the vent can become blocked.
Water Tank Level Gauge
The water gauge is located on the main power panel. This gauge will only operate once the domestic water pump
breaker is turned on and the button next to the gauge is pressed. Also next to the gauge is a knob that allows the
gauge to be calibrated.
Bleeding the Water System
Should you empty your water tank completely, you should fill the water tank, open all the taps and turn on the water
pump. This process will take a little time, as the clarifier will have to fill up. As the water starts to flow cleanly
through the taps, turn them off. Turning off the final tap will shut off the water pump.
Problems : -
Motor will not start: -
Replace upper housing or motor.
Motor runs but no water: -
Replace diaphragm/jammed check valve.
Low pressure and flow: -
Replace pump diaphragm or motor.
Pump very noisy: -
Replace lower housing.
Pump cycles too much: -
Replace upper housing.
Pump will not shut off: -
Adjust pressure in top of pump. Turn anti-clockwise using a hexagon key.
Shower Waste
The shower drain system works on the same principle as that of a domestic system. Water drains from the shower
compartment via the floor drain, passes through the water trap and then travels down a plastic pipe into a waste
collection tank. When the level becomes high enough the float switch will turn on the bilge pump and empty the
tank. Should you experience difficulties with the water draining away from the shower or toilet compartment, check
the plastic filter fitted in the waste collection tank (See page 6; Shower Sump).
Maintenance
Pre-season checks should be carried out on the pressurised water, the toilet waste and shower waste systems.
Should the water in the fresh water system develop a slight taint, we recommend the use of water tank
cleaner/deodoriser.
