    Water system for fire monitors and ECS
    I have laid out all the various components on a building board, not necessarily in the correct orientation/position. The only thing I do know is that water needs to come out of the 4 pipes pointing into the tin. I have a caravan pump serving as a water scoop (to simulate the
    water pickup
    as the boat moves forward) any water going through the system into the tin is piped back into the container under the bench where the pump is. First thoughts are similar to others in that when the fire monitors are operated the water is drawn back through the exhaust pipes and sucks air. To try and solve this I have put some small solenoid valves in the circuit. But first test show that they restrict the flow too much so a larger valve? Or I think the easiest solution would be to put another entry opening in the hull somewhere near the pump just below the water line on the side mid-ship so the pump can be connected directly and be primed when the boat is at a standstill (anybody see problems with this?) I think the only issue I can see is that when the boats in motion it may force water through the pump โ€“ then the monitor result โ€“ drip, drip. I think a properly designed inlet, that when in motion the tendency is to draw the air out of the system and not force water in until the boat is at a standstill when the water should just flow in. I have designed another outlet (not shown) for the exit of the cooling water and hopefully the smoke which has the water coming out of the centre 6mm pipe and the smoke exits through the surrounding space between the 6mm pipe and the 8mm surrounding hole. (Ignore the black pump, top right, it was a first attempt at a water supply, itโ€™s a car washer pump, but not powerful enough)

    Re: Fire Monitors Part 4
    Hi Martin, The cooling isnโ€™t pumped. There is enough flow round the circuit just from the motion of the boat and the pressure from the prop. At least there was until I fitted the valve. Havenโ€™t had chance to test it on the lake since I fitted that. If necessary, I could change the plumbing so that the pump is in the direct line from the
    water pickup
    and runs all the time. That would increase flow through the cooling circuit, and the valves could still be used to switch the flow between cooling and monitors. Graham93

    Evening Colin, Nowt on the haunted fish tank so I took another look at your pics. Something was itching at the back of my mind! Looking again at the last pic it occurred to me. I think I would be inclined to reverse the yoke on the rudder post, otherwise it's going to be blocked by the
    water pickup
    / water tube ๐Ÿ˜ฎ Just a thought. I still get one once in a while ๐Ÿ˜ Cheers and G'night all, Doug ๐Ÿ˜Ž
