The valve should be near the transom on the same side as the holding tank and you do not use the macerator when you pump out. Only 3 miles off shore (or anywhere in the Bahamas - gross).

Morning Phillbo!
I have been in that area of the inter hull (bilge, engine compartment, engine room, machinery space!) and have not seen a y valve!
Thanks
Don

Locate the waste hose going from the holding tank to the deck pumpout fitting. if it is a direct run there is no Y-valve and the boat is not equipment for over board pumpout.

My boat has a dedicated hose for the deck pump out, and a separate hose going directly to the macerator pump, which is sitting on top of the holding tank.

Hi Speedy!
I have a overboard pumpout, but I don't think I have a Y valve!
Will have to look closer, but I don't think there is one!
Thanks to all!
Don

Well I've not got a Y valve so I headed to the pump out.
Praying it wasn't going to be like the film RV lol
I pumped her out but it wouldn't lift the last inch or so of waste but at least it did the rest without incident.

Some times you need to add water to the tank. Also if it's been in there for some time it will solidify, water and wave action may break this up.

HI all!
I finally was able to get into the bilge and look for a Y valve! Don't have one!
One less thing to have to try to get to when cleaning holding tank!( I am setting it up to pump out through a hose into my RV dump system)
No I will not use it on the water, only when I dump at home or at a RV dump station!
Not all of the lakes here have pump outs, so I have improvise!

Sounds like you have a good solution for having limited resources for pump out.

Not all boats have Y valves. Mine doesn't have a Y-valve. My holding tank has two discharges; one to the pump-up deck fitting. The other to a macerator which goes to a through hull.

I have two momentary-On switches at the helm. Them must both be thrown together to actuate the macerator. This prevents accidental discharge. That is sufficient in my area.

Y-valves are the old way to bypass the holding tank and discharge directly overboard. Unless I'm on an inland body of water in which the local municipality requires a Y valve be specifically locked closed, then there not be a need to add an extra $25.00 item in the bilge unnecessarily.
