I have no documentation for the boat. Are there valves that need to be opened? If so where are they? Do I turn on the macerator pump? Do I need to run the electric toilet. Could someone let me know the procedure? No you do not need to run the toilet. Is your toilet a self-contained system--iow, the tank is directly below the toilet...no plumbing to a remote tank anywhere--or do you have a separate toilet and tank? Regardless of which system, you SHOULD have a line coming off the tank (it's usually at the bottom, but could be on the top with a pickup tube inside the tank) that goes to a deck pumpout fitting...that fitting will look very much like your water and fuel fill fittings, but will have "waste" stamped in the flange. To pump out the tank, you only need to connect the pumpout to the that fitting...the dockhand should be able to tell you how to do that. The pumpout will then pull the waste out of the tank...it does not need any help from the macerator. It's possible that there is either a tee or wye fitting in the pumpout line--one side to the deck pumpout fitting, the other side to the macerator and then to an overboard discharge fitting. As Keith has already pointed out, it's illegal to dump a tank overboard in any US waters...you must be out to sea at least 3 miles from the nearest point on the whole US coastline to dump a tank legally. If there is no deck pumpout fittng, the tank cannot be pumped out...only dumped using the macerator...in which case--depending on the waters you're in--you'll either have to to install a y-valve (you could use a tee or wye fitting, but CG regs call for a y-valve...aka known as a "diverter valve") and deck pumpout fitting to give you a choice between having the tank pumped out...or--if you're not in coastal waters that provide immediate access to open sea beyond the "3 mile limit"--re-route the tank discharge hose to a new deck pumpout fitting. Bottom line: to find out what you can do, you're gonna have to trace your sanitation plumbing to find out where it goes. Ok...now I'm gonna beat you up a bit: why did you use a system on your boat before you knew how every part of it works? This time it was only your holding tank...but for all you know, you may have damaged the toilet. And if you also used the "just turn the key and go" approach to everything else on your boat, that's a very good way to find yourself several miles from shore--even in a lake--with a boat that's taking on water, a dead engine...and without a clue what to do about it. 99% of problems with any system on a boat are caused by owners, ,and could have been prevented...they're caused by ignorance of how to use systems, ignorance of how to maintain any of 'em, resulting in neglect of small problems until they become big expensive ones. So for Pete's sake, learn how everything works and how to recognize when it isn't working properly! However, to your credit, you were paying at least enough attention to know that your holding tank is full and did ask how to empty it...that is, unless you only found out that it was when you saw waste spurting out the vent. -- Peggie ---------- Peggie Hall Specializing in marine sanitation since 1987 Author "Get Rid of Boat Odors - A Guide To Marine Sanitation Systems and Other Sources of Aggravation and Odor" http://69.20.93.241/store/customer/p...40&cat=&page=1 "when you saw waste spurting out the vent."
