Hi, we just purchased a 1987 Newport 28 II and are in the process of fixing her up. One issue I'm having is that the head is shot and keeps filling up with water. I think I've shutoff the seacock for the raw water but it is still filling. I assume there is a syphon action with the
holding tank. Can anyone tell me where all the relevant seacocks are? I shut off the gate valve under the sink in the galley. That is the raw water intake for the head, correct?
Anyway, any advice would be greatly appreciated. I don't want a disaster.
Thanks!
