Hello all, we recently purchased a 21 American Eagle 45K. It has extremely low miles but needs some love. Had a lot of issues that I've been checking off but the toilets have me stumped. It has SaniMarin marine toilets. No water runs in the bowl when activating a flush. Yesterday I checked the power going to the water inlet valve, I cleaned the inlet valve screen, I removed the hose that goes from the valve to the bowl and blew air through, no obstruction, I checked that the controller is working properly. With the hose removed, I activated the flush and let the valve empty into a plastic jug. The valve opens and water passes, then stops for the flush time, then opens again to fill the bowl. There seems to be a fair bit of water pressure coming out of the valve, but no volume. I'm sure the valve mechanism is gummed up because the fresh water tank was pretty bad but nothing seems to make a difference. I have the panel programmed for max fill time already, but unless I figure out how to get more water passing through the valve then the toilets won't work properly. I would just buy new valves, but I can only find them in Europe and they won't ship here. Any thoughts??
