How to locate Macurator Y vlave for Sailfish 272

[alexander.rodov]

Hi there Grady White enthusiasts.
Got myself 1995 Sailfish 272. Love it.
Have trouble locating Y valve for the Macurator. Was trying to look up in the manual, could not figure that out. Looked under the lower deck, no luck either. Please help. Thx, Alex

Have you located the macerator pump and holding tank?

No y valve just seacock for macerator pump out and connection on starboard walk around for marina pump out
Under the cap in cabin floor port seacock is pump out and starboard seacock is intake for flush

You may not have the overboard discharge option. If you do have it, there will be a separate seacock for that function and it will connect to a larger diameter hose than typical for the seacocks for raw water. livewell, head flush water etc..
If you find a msd discharge seacock follow the fatter hose backwards . Your macerator pump may be built into the holding tank also.

There is a macurator switch with 3 lights indicator (red, yellow, green) and pump button. When I turn on the switch all light are lit and and there is sound indicating that the tank is full. Whan I try yo use the pump button to bump (only do this offshore), I do hear the sound of the pump, bot no discharge going out of the seacock. Maybe the pump or the indicator is out of order.

At least on my 2007 282 there is no Y-valve. There is no commonality in the two different discharge lines. I'll try to show.

In the forward bilge is the overboard discharge seacock. It is the one on the right with no handle on it - it has never been and never will be used, although I turn it once in a while.

You have to remove the aft panel in the aft berth to see the inner workings. Only one line exits the pump that sits atop the holding tank. That line runs to the discharge seacock in the above photo. There is only one line (labelled Marine Fuel of all things!) that runs in to the holding tank (closer to the left foreground in the photo), obviously from the head. Two lines run out to the left in the photo. The slightly smaller diameter line runs to a vent on the starboard side. The slightly larger diameter line runs to the pump-out outlet, which, on my boat is located on the deck of the starboard walk-around. That line is not internally pumped, it depends on the pump of the pump-out station.

Hope this helps.

Personally, since we will never use overboard discharge, I'd rather remove this whole works and replace it with a portable toilet. Then use this space for a marine AC unit. But I fear pulling out the holding tank will hurt the boat's resale value.

So, you remove the handle to meet the USCG requirement inshore, that it be mechanically locked in the closed position?

 

[Sailfish]

In my 2000, it was in the cabin floor under a round cover between the head door and galley.

The seacock also must be open in addition to the Y valve.
It is also possible that the valve is open, your seacock is open, but your macerator impeller is shot, a common maintenance item

Yes. Also, we were hoping that Canada would make the decision to allow vaccinated travelers in during our recent trip through the Great Lakes. I was advised that keeping the handle under lock and key would satisfy the Canadian requirement as well. Alas, Canada did not make the announcement in time for us on our trip.

The valve has to be in the 'disable overboard discharge' position and not easily changed. A lock is fine but in the US ( don't know about Canada) so is a zip tie. I guess removing the handle is OK as long as the valve can not be changed without the handle.
On some electric systems there is a key switch that disables the overboard discharge pump (as long as you don't leave the key in the switch
