So we have picked up our new boat and I was surprised to see (hear) there are no alarms on the bilge
pumps when they are running. Surprised this would conform to CE standards as well. Problem is if there is water
entering, we have no way of knowing till it is over the floorboards or worse.
There is a visible light at the panel which comes on when they are running.
So my question is, how to fit an audible alarm
to the system? Its a cat, so 2 bilge
pumps. Is it best to fit an alarm
to each at the pump, or a single
alarm inside the electrical
panel connected to the switch or LED's somehow?
Also, I would like to have a louder alarm from the Raymarine
e125 plotter than the built in beep beep. Is it possible to connect an external alarm?
One other question on bilge pumps, ours runs about 12 inches to a check valve, then T's with the shower
waste before being sent overboard
. I have noticed when we use the showers (both sides) a small amount of water
flows back through the check valve and into the bilge (maybe 1 litre per shower) Is that normal, or should check valves stop ALL water returning? I don't like the system as I prefer keep the bilges bone dry so I can monitor
for any leaks
. This system is ensuring there will always be some water in the bilge and the bilge pump
will have to run occasionally to clear some of that water. The keels have been filled with a small sump space left for the bilge pump
which holds approximately 10l of water. The most the pump can evacuate is about 9 litres, leaving a 1cm deep puddle in the sump.
Any thoughts on a fix to any of these items most appreciated !
