We have just replaced ALL the head hoses on our Hunter Legend 35 (1987) in hopes that we can reduce/eliminate the odors that build up in the cockpit locker (where all the tanks and hoses are). The hoses may be original, though I'm not sure.I used high quality flex hose and Sch80 PVC pipe (with flex joints) for sections where sewage would be standing, and I am glad to report that one day later the smell (which was very strong in the locker and slightly less strong in the cabin) is now almost completely gone.To help prevent the hoses from getting stinky too soon, I'm going to be posting "head" instructions to help ensure that people use it correctly. We have the standard Jabsco marine head. Here is what I was going to say (any thoughts?):Rules:1.NOTHING (no exceptions) goes into the head unless youfe eaten it first (except single ply toilet paper)2.Guys should sit down (first choice), and clean up after themselves.Instructions:For Number 1:1.Go pee2.Flip lever to gwet flushh3.Pump until water runs into the bowl for about 2-3 pumps to rinse the bowl (not too much water, it fills the waste tank)4.Flip level to gdry flushh5.Pump lots; maybe 20 times (get the waste to the tank!)For Number 2:1.Use the sink and a cup and pour a few cups of water into the bowl until it has a few inches of water in it. (gwet flushhs do not leave much water in the bowl)2.Have a crap3.Use minimal toilet paper. If you need to use a lot, do it in two passes.4.Flip level to gwet flushh5.Pump until waste has left the head and bowl is rinsed6.Flip lever to gdry flushh7.Pump lots to get the waste to the tank; maybe 20+ timesThanksChris
