we just pressurized our tanks last weekend (thanks for the advice).while draing we noticed our forwar sink was leaking around the base of the sink.either a bad seal or a crack in the white plastic (what looks like trap)..our aft sink is a very slow drain......I was looking to replace both "traps" however can not find then in Boat US or west marine...do they need a trap or will a 90 degree suffice?thanksrobPS these "traps" look like a small white round cup at the bottom of the sink almost ball shape.with the hose connected at a 90 degree angle.
