Re: [Amel Yacht Owners] Sink/Shower grey water

Greetings Roger,

I confirm that Judy's response answered my question, as the question was intended. But, thank you for your considered response to the original post.

I am heartened that Judy, Ian, and Serge are satisfied with the yard's drains arrangement.

Judy, are you not able to achieve an (almost) empty bilge with the manual bilge pump?

Hi Ian

I would agree with you and Judy if the original post was about what
you are suggesting, but I read it differently and was awaiting his

By the way, on my Mango, the sink and basins empty through the side,
above the water line, and only the shower goes into the sump by
gravity and is emptied by the bilge pump. I once gave consideration
to recycling and it was from that experience I responded; I realized
I am well off with the Mango arrangement, and could be more so with
yours as you get even more soap regularly neutralizing any bilge
greases. Not sure about food scraps from the sink though, sounds
disgusting and likely to clog the bilge pump; no wonder Judy reports
have to clean out the sump which i don't seem to need to do.

I really don't think it's in the spirit of a forum to browbeat other
respondents, which is likely to frighten them away (not me though, no
worries). Wish I'd had the same level of response when I requested
the section diameter of the forestay recently (twice).
