Pumping Out Waste at Sea

[Wunu]

Sorry all, I only have access on my phone and can not do an adequate search. I am trying to find out what sort of fitting I need to pump the waste from my holding tank into the ocean by way of my flush mount tank fitting.
My 28' Mariner is fitted with a manual pump in the line for this purpose but will cover the deck with effluent unless I have some sort of adapter to send it over.
I feel that I had seen a thread here once before that addressed this but just can't find it. If someone doesn't mind rehashing an answer for me, or pointing me to that thread I would appreciate it.
Thanks.

That was meant to read "flush mount deck fitting" oops.

A piece of hose (snug fit in discharge fitting) long enough to go WELL over the size?

[gonesail]

that is a strange setup .. all the overboard pumps i have seen pump thru a sea cock underwater .. why would they expect you to pumpout to a deck fitting?

We just pumped out for the 2nd time ever and it all makes more sense to me now. We have been mostly using the Marina head since it is so convenient! Had to bite the bullet and learn how it all works today so that we can transit the ICW where there is no 3 mile limit for us! Thanks for the reply, I am guessing West Marine or somewhere like it will have the fittings we need.

raw pumpout is allowed in the iwc??

[Wunu]

Gonesail, we have (in this order) an inlet seacock that goes to toilet, then a hose to a Y-valve to either straight out to sea (outlet seacock below waterline) or the holding tank. From the holding tank we have a hose to the deck fitting to suck out at a pump-out station. On the hose that leads to this fitting there is also a manual pump mounted to the bulkhead about a foot under the deck fitting so that we can empty the tank by hand when we are 3 miles out. Our tank is a very small bladder type maybe 10 gallons so I imagine we will need to use this option on occasion when we can't get to a pumpout but can get to open water.

Sara, I was trying to say that we need to use the tank because we won't get to flush straight over in the ICW like when we are 3 miles off. Until now, we did not need to worry about the tank because we don't use the head until we are out where it is legal.

[Wunu]

Oh and Sara, we are only planning to pump out manually when there is no pump out facility and we leave the ICW for day sail or something like. I need to learn to write more clearly on these threads. I'm new. It seems so clear to me when I am thinking it! lol
Thanks again for responding.

AH, got it!

so glad I misunderstood...

Would it be worth it to relocate the manual pump between the tank and the y that options for overboard below the waterline?

That would allow you to ... no it wouldn't. the y wouldn't work that way...

hrrmmm.

Still seems that a hose of the correct dimension and sufficient length to control spillage and spatter might be the simple way to handle this scenario...

Seems to me the simplest solution would be a y-valve in the pumpout line--between the tank and the pump--and a piece of hose long enough to to reach from the pump to the thru-hull your toilet is already connected to. A tee or a wye to connect to that line.

Now you can dump the tank below waterline instead of splashing it all over the side of your boat, which is what you'll do if you send it over the side from the deck pumpout fitting.

I suggest you get some on-site help to spec out EXACTLY where all the new parts should go...my psychic powers aren't quite good enough to visualize it from here.

composting head, cough cough

My thinking now is to keep it as is and get an extra length of "stinky slinky" hose to reach the waterline from the adapter and hopefully cut down any spatter. It's a small boat 3 or 4 feet should do. More importantly, I will position myself below working the pump and get my unsuspecting husband to handle the discharge end of the thing the first time.
What a great resource this forum is for bouncing around ideas. Thanks y'all.

Have you thought about where you will stow this 3-4' (which should prob'ly be closer to 5-6' if you want it to discharge below waterline) length of smelly hose that will dribble sewage because you won't have any way to rinse it out? And which will dribble all over the deck around the fitting when you disconnect it after using it too... I suspect that you MIGHT be able to get your hubby to deal with the hose and the deck fitting, but I doubt you'll be able to talk him into going over the side to retrieve the hose if it's dropped an attempt to "dredge" it to rinse it out...

You already have the below-waterline thru-hull...and you already have the pump. A y-valve and a tee fitting, and some hose...and you have a means of dumping the tank that you can stand to live with--and can be done by just one person!

Sorry to hijack this thread but;

Peggie, have you had a chance to look at my web page yet? I've sent you two e-mails.

Thanks for you help
