Where does the grey water go??

25 posts in this topic

Spent the weekend learning all the systems for my new 2018 264 Sunesta.  The toilet flush goes into the holding tank... does the water from the sink go there as well or does that get discharged overboard?  Thanks in advance for the answer.

It depends on where you boat. Some states required all water to be drained to a holding tank. We purchased our boat from a seller in New Hampshire and it was plumbed so that all water went to the holding tank. Florida does not have that requirement, so I re-configure the gray water drains to flow overboard.

Most sinks go overboard.  There used to be diagrams in the owners manual on what all the through hulls were for.  The shower on ours goes into a sump, then out over board.  We use biodegradable soaps we found online.

I went through the Owners Manual and that was pretty much useless.  Only diagrammed out the water supply but not the waste lines from the sink.

Turn the water on in the sink and walk around the boat. If you see water draining overboard then you know you are not draining to the waste tank.

Download "parts list" for your boat from Chap site. Chances are, it will have the pictures of your boat with most thruhulls identified correctly, plus some other diagrams and info.

Most showers and a/c units are below the water line. Were the sinks are not. So a sump pump is needed.

Are you sure it was not a bilge pump discharge?

As said elsewhere on the forums recently, know your boat ...

I am sure.  Bilge comes out of a different port.

Just open up the hatches and look for the hoses.  I bet they will lead to the bilge.

They absolutely do not lead to the bilge, speaking as a 264 owner.

I could say that speaking as a Chaparral owner In general.

I wouldn't be surprised if you own or just got out of another brand boat.

I have never owned a boat where anything drained to the bilge.

The retractable cleats do, without and with the drain tubes installed. The tubes, if installed, go to the bilge.

Food bits ?  Wine sugary liquid ?  Body bacteria ?   Being added all the time.
