When we purchased Jan-kees, there was one water tank, 500 Liter. So last year I installed a 2nd water tank. Part of the sage is here and here.
Because I do not want to go into the bow compartiment each time to connect, one of the two tanks to the pump, or turn a valve, I bought 3 electric 3/4″ 24V valves, with a manual over ride. One for the inlet, and then one for each tank. So either both tanks can be filled, or tapped, or just one. And yes with float switches I can grab an Arduino or a Raspberry Pi and let it control the valve functions, fill both and when one is full, and the other is not, close the valve on the full one. Or use it to use the water level to level the barge. Another winter project.
So diving into the hold I mounted the 3 valves and turned on the pump…..but no luck…it kept sucking air. I suspected the 4 way connector. Removed all, cleaned all, reassembled and tried again….Again. just cold air, not even hot air !.
I just connected both tanks with a manual valve to the pump and it worked. Must have been the connectors? So I ordered new ones and just waited til then. Of course hot weather came, windy weather came, rain weather came, and then some time with some sun, so I dove in again. The trick was to push the Tyleen in deep enough so the rubber ring seals it. Duhhhhhh…..
So the system worked, now I have to just connect the valves to the control box and we can manipulate them from inside.
The box has 3 push buttons, and it should be obvious which one controls which one. The inlet valve is extra ‘protected’ with a little cover guards, so it can not accidentally opened. When it is open, the pump will not prime. Each tank has 2 float switches, currently I am only going to use one, but with 2 I can have a nearly full and a really full alert.
The push buttons when pressed in lights up the led and the white wire goes positive, when not pressed in, the blue wire goes positive.
The valves use connection 1-3 for open. and 2-3 for closed. (3 being negative)
When I connected the port float wire to the flashing/buzzer light, it started to buzz. OH dear, I missed checking the correct orientation of the ‘floatie’ on the float switch. Crawled back into the bow compartment, and by using my past training by Houdini and an Olympic gold medal winner turner I was able to reach deep enough in the water tank and just on feeling flip the ‘floatie’
Now just for record keeping
|Port Valve||Red = open (1)|
Green = close (2)
|Starboard Valve||Red = open (1)|
Green = close (2)
|Inlet Valve||xxx = open (1)|
yyy = close (2)
