Hi Sean,
Enjoyed following your head replacement project. Learned a lot. Of course my layout on an E-28 is different from yours but tanks are tanks and hoses are hoses and what goes through them is all the same on different boats.
You mentioned a fresh water flush system in the project. I can guess at the connections from the photos. It looks like the sink drain is connected to the raw water heat inlet at the seacock with a T or Y fitting? Is this the way it is set up? That seems to explain the sucking in air phenomenon since the water in the hoses will just be up to the water level and get sucked down when you pump the head.
Did you eliminate the original through hull for the sink drain to make this arrangement? Your comments gave me the idea to make a similar arrangements except to keep my original sink drain but put in a Y valve which would select between normal overboard discharge through the existing through hull and to a hose connecting to a T fitting in the head inlet.
To flush the head system with fresh water, direct the sink drain Y to the head inlet, close the head inlet sea cock, fill the sink, and pump away.
This would seem to solve the air sucking problem since during normal operation the sink drain would be directed to the normal through hull and blocked off from the head inlet. On the other hand, if you think space was tight behind the vanity on an E-35, it's going to be even tougher on my E-28. I may run out of room for lines.
Would appreciate your (and other folks) comment on this and more details on this drain layout in your E-35.
Take Care,
Jim R.
