Hi Ray,

Thank you: worked like a dream! Into open water, insulating tape and rubber glove for seal, and bingo! Never had a holding tank before, so was quite worried.

BTW, when conneccted to shore power, is the battery charger suppoosed to be quite noisy? I’m not used to inbuilt chargers: used to use an Optimate on my previous boat, which was, of course, totally silent!

Thanks again,
