Gary, I have to confess I didn't quite get all of the finer points of your description; would you possibly have a diagram or drawing of the system? Thanks

Ever since, it has been my mission to build a system that would work properly; that is, no leaks, no smell and can't syphon when the uninitiated left a valve in the wrong state. After many attempts and changes, over the years, if feel I have accomplished my goal. I have received many ideas from others including Peggy Hall (the head mistress) and probably a few adult beverages along the way. I'm an engineer, not a writer, so the fact that you could understand my babbling, speaks more to your brilliance than mine. If you ever want additional details on my system, just let me know.

In the case of my boat there were times when the level of the effluent in the tank was above the bowl in the tank. In my case the tank is transverse in the boat (head on the port side) and when on starboard tack the fitting on the port side of the tank is submerged and the effluent pressure goes back to the joker valve. The joker valves are never perfect and they will leak some. What I did is run a pipe through the tank from the head fitting in the tank to the opposite side of the tank, so the fitting is on the port side but the pickup is on the starboard side. Then when on starboard tack the effluent sloshes to port and the pickup is out of the effluent. When on port tack, the pickup is submerged, but is below the level of the head so it doesn't matter. That solved the problem for me. Does that description make any sense to anybody?

For the last couple of years I have done an annual job of flushing a bunch of fresh water through the system, and then pouring about four gallons of cheap white vinegar down the head. I make sure some is in the bowl, and that the hoses are full of it. I let it sit for a day or two, then flush the whole system with fresh water. After that job I need to disassemble the pump and lubricate the O-rings with silicone grease. This particular problem sounds like a bad joker valve, though. Wal you wrote: Salt from urine crystallizes on your joker valve and the joker valve leaks back. Ideally we are supposed to flush clean water thru but it never happens on the Great Lakes when you are trying to conserve holding tank space. -- s/v Stella Blue www.wbryant.com _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com [email protected] -- ~~~~~~~_/)~~~~~~ _______________________________________________ his List is provided by the C&C Photo Album ttp://www.cncphotoalbum.com [email protected] -- ~~~~~~~_/)~~~~~~ _______________________________________________ his List is provided by the C&C Photo Album ttp://www.cncphotoalbum.com [email protected]
