whats this (waste) cap for?
 

84 f302 boat with a porta toilet....

i see were the lake water comes in for the toilet, but were does the waste go??
by the gas cap on the boat theres another cap that says (waste) what are you suppose to do get that sucked out??
how do you do that go to a marina?

thers aholding tank on the boat. yes it needs to be sucked out. not at a marine but a pump out station (on the water)if one is in your area or pump out boats.

Ask any local cruiser owner where they get the holding tanked pumped out. Full service marinas will have a pump out, usually at one end of the gas dock. Some are free, most charge a few bucks and use a suction hose to empty that holding tank.

Hold on a minute Mookster, we need to visit this whole potty thing a little closer:

You say your 302 has a porta-potti. So, there is likely not a separate waste holding tank. The tank is the base of the porta-potti. Look in the potti room and see if there are fittings and hoses hooked to the porta-potti.

You also said you can see "where the lake water comes in". If you're seeing the valve in engine bay on the bottome of the boat, that is not incoming lake water - at least it better not be. That is the offshore discharge from your macerator pump. Look under the front cushions in the bow and see if you have a macerator pump. If you do, and if your porta-potti is still plumbed as it came from the factory, then the waste hose goes from the porta-potti to the macerator. From the macerator you can direct flow to either the waste pump-out or the discharge valve (I think).

In any event, you need to check out all of this plumbing very carefully and make sure it's in good shape and still connected tightly. You can imagine the outcome if its not. Do this before you hook up to one of those marina vacuums.

And, it may not be connected. I removed all of the waste plumbing from my boat and capped of the pump and valve. Couldn't stand the thought of KA-KA stuck in those corregated hoses. I just use the potti as a true porta-potti taking it out to empty it. And of course, only the girls can use it. Guys, jump overboard and do your thing.

Know also that if your through-hull discharge valve is still connected and functional, you cannot use it on inland waters and you can only use it in the ocean if you're far enough out, I think it's five miles but I'm not sure.

TB is correct on my 311 the porta potti has a 2 inch waste line coming from the rear and goes back to a Y-valve in the starboard side storage area behind the driver. if the valve is switched to the waste fitting you can pump it out. If it is switched the other way the waste goes through the macerator pump and out the hull below the starboard engine(ewwww). If the Coast Guard inspects you and finds the Y-valve not secured in the pump out position (use a wire tie) you get a heap big fine.

Something about this whole thread stinks....:poopoo:

thanks alot. i have to leave town but will let you know what i find when i get back

Wow, I haven't heard the term "KA KA " used in a long time. :eek:

Where the fitting comes thru the deck..is it a flush fitting?

Isn't this somewhat of a double standard here? Get Bob's dog Ginger to dig you a hole and keep your chit in your Pond.

Basic plumbing rule is that chit flows downhill, better not see any Bird turds floating thru the Bay! :eek:

Unfortunately He's right ..... AGAIN !!!! Dolt!

What's really funny about your post is what Third Bird does for a living....:eek:



Dave

Doh!!!

Didn't really know how to spell it. :o

I think you spelled it just fine. :p

ok i got home and looked.. the big line is going to the pump and its run right out the side of the boat!
then theres a small one inch line also goin in to the toilet.

there is another 2inch line but it is capped off.. that must of went to the holding tank??

is the holding tank hard to remove?

The one inch line should be just a vent from the toilet to a vent thru the hull ...there should be a about 1.5" line from the toilet to the Macerator then out of the Macerator to a "Y" Valve that will allow you to either pump the waste out of the head to the Thru hull in the engine room out of the boat (illegal) or to the sewage discharge cap up on the Starboard deck .....If its not like that ..someone has changed it ....m

is there anyway to get to the holding tank.. like to clean iy ouy good
