Peggy,O'Day built the head system without any vented loops. Many manufacturers are still doing the same thing. I see this from other new boats with the same problems. Groco on it new head did not put hose clamps on the water line and after a year the hose will come off. All this to save a few dollars. With all the concerns with polution from fuel spills it is only a matter of time until the manufacturers find that by saving a vented loop and a few feet of hose a high final price could be the result. Most of us are sailors not plumbers.Thanks again
