Hi ,just been messing about a bit and trying to understand how things work.I can run the galley water and the bathroom water using either the vanity or the shower ,no water comes out the side of the boat at all ,but I took a look at the sump pump and I noticed any water from the galley and bathroom(that has gone down the drains) ends up in the sump,but then runs down into the bilge,I removed the sump pump and when I turn it upside down it runs or if I lift the float up it will also work .My boat has a freshwater tank in the starboard transom area,which I know fills when I run a gardenhose into the filling point on the port side.I also checked the other 2 tanks in the mid berth which I presume are a black and grey water holding tanks,they both seemed to be empty or have almost nothing in them.The question is why does the water go into the sump and end up in the bilge? shouldnt it go into the tanks ,or overboard? either way I want to alter things so they all drain overboard ,then remove the unused grey and black water tanks to provide extra storage ,can anyone help me with how to go about this? do I need a macerator? my boat doesnt have a macerator ,but does have the spare switch in the head marked 'toilet' it does nothing(as far as I can tell) any help would be fantastic!! ,thanks again,Mike
If the sink water runs directly into the bilge you do have an issue. Either a disconnected or severed hose to the grey water (or overboard). I'm guessing a disconnected hose to the tank at this point, however.
If you want to use a macerator to purge black water, you will still need a black water tank. I have never seen a setup that moves waste from the toilet directly overboard. The systems I have seen always put waste into the black water tank and the macerator is activated by a switch which "sucks" the waste from the black water tank through the blades and overboard. This might be a great use for the unused toilet switch in the head. I have that switch as well, it doesn't do anything if you have a manual pump toilet. But you could make it run the macerator if you added one.
Regarding the grey water tank, yes if you reconfigure, you can get rid of that tank. If your sinks and shower drain overboard and your toilet water is pulled from the seacock, you have no use for the grey water tank.
