Head/waste designs on DE

[jerseysportfisher]

A while back not sure if it was on hear or noreast, pretty sure it was ronnie who said that from the head to the waste tank was connected, from the tank to a seacock. While under way if you crack the seacock, the suction will pump out the waste tank ? is this standard design on the DE ? or do they have macerator pumps ?

My boat has a gate valve that will allow me to either pump out from shore or pump into the ocean. No macerator. It has a manual pump to suck the goo out and push it down through a seacock.

I've never tried leaving it open to see if a venturi effect would suck the tank clean. I somehow doubt there would be enough vacuum generated for that.

But the setup is CG legal as long as I have the valve locked in the correct position while inshore.

I don't have a macerator. I use a hand-operated pump with the set up below. I can pump FROM either the head OR the holding tank and pump TO either the holding tank or overboard.

Also has a pump out connection along the gunwale. Set up works great.

I dont have overboard discharge on my boat. I have a pupout station near my dock. I can tell you what made a HUGE difference on my boat was to install a fresh water tank to flush instead of salt. I also add a little of that blue deodorant to the flush water. No more smell from sitting salt water.

Well aware of that part, already have a seperate 20 gallon fresh water tank for the head.

That is how mine is set up and I'm probably the person who brought it up.
Best to ask Mudhake about it as he built my boat and set it up, although when I bought my boat it had a manual hand pump toilet and I replaced it with an electric head that has a macerator pump on the toilet that both pumps raw water in and grinds & sucks out waste to the holding tank. Only reason I replaced with the electric is that I"m sure girls on my charters whould not want to be hand pumping and the fact that I had a new electric head from my prior boat.
From the holding tank the discharge hose is at the base of the tank and goes to a seacock & thru hull.
While under way with seacock open is sucks the tank dry in seconds !

YES!!!! thats what i was looking for, now do you leave the seacock open all the time or just underway ? i would think if left open all the time you would need a vented loop no ?
