Head holding tank switch

[Donn]

I just purchased the hunter model 31 and noticedthe black water from the head was coming out ofthe starbord through hole. Can anyone tell me wherethe switch is so the black water goes into the holdingtank?

It may not be the same as original!

Donn:It may not be the same as original. The original plumbing layout was designed so the boat could be setup for holding tank storage or direct overboard discharge.We had ours replumbed so we always discharge into the holding tank. Then we can determine which way to empty the holding tank.AS I REMEMBER, there is a 'Y' value under the V-berth on the port side. The value in one position is for the holding tank the other position is for direct discharge.

There's more than one possibility

As Steve said, the plumbing may not be "factory original"...so you're gonna have to find out for yourself where the hoses go by tracing them (something every boat owner should do ASAP after buying a boat anyway ...an emergency is NOT the time to START looking for y-valves and thru-hulls!). A y-valve that offers a choice between flushing directly overboard and going into the tank is usually fairly accessible, so it shouldn't be too hard to find if there is one. However, if waste is coming out a thru-hull fairly high on the hull, it prob'ly means that waste is going into the tank but the tank is full and waste is overflowing out the tank vent. Or, you may not have a holding tank--or if you do, the toilet may not be connected to it. but only flushes overboard. So...there's only one way to find out how your sanitation system is plumbed and what's happening: start exploring your own boat.
