Andre K, 1991 Hunter 30

Hi Peggy! I read all of your answers, you are the Queen of sanitation! I have a question regarding the Y valve: My hunter was (factory?) equipped with the aluminum holding tank. The tank has three outlets from the top - one is the IN discharge from the head, the other is an OUT to the Y connector which splits to PUMP-OUT and to MACERATOR, for alternative use where permited, and the third is the vent of course. Q: I will be installing new pipes and perhaps the new "plastic" tank: should I / do I need to - instal a proper Y valve to ease with emptying the holding tank(prevent loss of suction), or the Y connector is sufficient? Thank you very much for your input! Andre s/y Schatzi

Same Situation

I am in the same situation and would be curious to know the difference. Should a Y-valve be installed or not. I guess the danger is to the macerator pump's impeller when a pump-out vacuum is activated but how dangerous is it?

I may be mistaken but

Don't coast guard regs require that if you have the potential to disharge overboard via the macerator that there has to be a way to lock out that potential? I am 99.9% sure that Canadian boats coming into US waters are required to have a lockable y-valve to prevent accidental/on purpose direct discharge.

Definitely y-valve.

If for no other reason, to provid a means of closing off the flow from the tank to service the macerator. David, CG regs do require a means of "securing" the system...however, unless the discharge thru-hull is above waterline (YUK!), securing the seacock is all that's needed. Rob, a pumpout has no impact whatever on a macerator impeller.
