Len,My experience does not agree with yours, with the idea that both the
anti-siphon valve and head check valve have to be malfunctioning to fill the
bowl with clear water. Ours filled with clear (sea) water until we replaced
the head check valve, and we have no indication of a problem with the
anti-siphon valve.Replacing the pump on the Jabsco head, including replacing
the joker valve solved the problem, and it's been fixed for almost a year
now.We've also not had a problem with the sink in the v berth filling. Just my

Stus-List C&C37+ starboard tack / head Edd, BOTH the anti siphon valve and head
check valve have to be malfunctioning as others have said to have the bowl fill
with clear water. Black water would be a joker valve issue if you use your
holding tank. We also have an issue with the V berth sink on a port tack
filling with water so I installed a 1/4 turn drain valve because the thru hull
valve is so difficult to access. It only happens 7.5-8.5 knots. All good now
because she has been sitting on her steel cradle for a month!!!Len
