Hi Victor,
Our boat, Tara, 2490 had a rubber bladder waste tank when we got it. Not
good as far as we were concerned. It was not new and retained an unpleasant
odour. Also it had only an inlet and an outlet, no breather outlet to let
odours and/or pressure build up dissipate so we replaced it with a waste
specific rigid "plastic" type of tank.
Iver
