Thanks very much for the advice. Indeed a whale gulper with flow switch seems a much more elegant solution, I simply didn't know they existed! There are a few cost effective kits around I see. Now to plan this semi flexible wet room! Cheers

Hi all, My partner and I have bought a tiny 30ft cruiser stern narrowboat which we are now living on (we quite like small spaces). We currently have a toilet room near the stern next to the engine bay which I have an idea to turn into a wet room and install a shower. The floor of the wet room is lower than the cut water level which means a waste tank will be needed for grey water from the shower. I'm thinking of installing a grey water waste tank like those used with caravans in the engine bay (there's plenty of room) which could then be emptied using a standard 12v submersible pump. Any advice or suggestions on this idea? Might there be a BSC issue I should be aware of in terms of draining into a tank in my engine bay? Thanks for any help, Will
