Our new to us boat has screen washers at 3 lower helm screens. Where is the reservoir and filler? I can see two holes portside in the coachroof and one starboard, might these be the fill spots, if so how, hose and hope?
Mine are fed from the fresh water supply and domestic pump are you sure you have a tank?
Does your domestic water pump run when washing the screens? If so, it will be using a solenoid operated valve and domestic water pressure to wash the screens from the domestic water tank. That's a fairly standard setup on a mobo.
Have you tried running them for quite a bit. Any residual pressure in the system may operate them without the pump running. Turn the water pump off and open a tap to get rid of any pressure. Then, with the tap still open, try the washers. If they still run, you will need to trace the pipework or check the domestic tank for a separate take off.
Can you post a photo or link to one of a similar boat?
