My 86 C-27 (new to me) has a Groco HF head
. On Tuesday I closed the seacock water
inlet to flush the head
. The bowl was dry, the lever was down.
The holding tank
was pumped out Saturday and used only a few times.
sailing for 5 hours with little healing. It was too hot to stay around when we got back to port so I went this morning to finish taking the stuff off the boat
. Today I looked into the bowl and it was full of some very dirty water
(didn't really smell). Seacock still closed. I opened seacock, flushed the head, emptied the bowl and closed the seacock again. I can't get back to the boat
until Monday and I suspect that the bowl will be full again even though I closed the seacock.
Is there a check valve stuck? Is the joker valve shot? What do this symptoms of?
