If everything on my boat worked as well as the Lavac, I would sail a lot
more. -- Dennis Gibbons S/V Dark Lady CN35-207 dkgibbons at optonline dot net "Karin Conover-Lewis" wrote in message ... Ditto the "Lavac" recommendation. I would have no other.

Peggy,
Have you ever heard of the following setup: The waste tank is ABOVE the water line with a bottom drain to a seacock. There is a second drain from the top of the tank to the deck pumpout. The head pumps up to the top of the tank. Close the seacock in protected water to keep the bad stuff aboard and then open the seacock when you get out.When offshore, simply leave the seacock open to drain as you go (so to speak). Real simple if you have the freeboard. I wouldn't worry about carrying the weight so high because the tank would always be empty out to sea. -- Dennis Gibbons dkgibbons at optonline dot net "Peggie Hall" wrote in message ...

I'm not crazy about that set up. When the seacock is closed waste has to sit in the line to thru-hull, permeating the hose...any sludge in the tank will end up in that hose, so if you're in coastal waters very long, that can cause problems...and I can't see any reason to go through a tank at sea instead of flushing directly overboard. If the tank vent should become blocked, you'll have problems flushing the toilet due to the backpressure. Worst case would be a blocked tank vent AND a clogged overboard discharge hose at sea in 8'+. -- 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://www.seaworthy.com/html/get_ri...oat_odors.html |

Close the seacock in protected water to keep the bad stuff aboard and then open the seacock when you get out.When offshore, simply leave the seacock open to drain as you go (so to speak). That is _nearly_ exactly the set-up that I have, with one important modification, see after Peggie's comment. Peggie Hall writes: I'm not crazy about that set up. When the seacock is closed waste has to sit in the line to thru-hull, permeating the hose...any sludge in the tank will end up in that hose, so if you're in coastal waters very long, that can cause problems Right. So what I did is to have a PVC ball valve right at the drain, then go with sanitation hose (the good one, of course) to the seacock. Both the PVC ball valve and the seacock are usually closed and only open off-shore for draining the tank. Thus, the hose ONLY ever contains sea water (or antifreeze, in winter), except for brief periods during draining. And after draining the tank I would pump enough sea water through it (using the existing pump, i.e. through the head) to make sure it is clean before closing both valves again. Just like you pump fresh water into the tank when pumping it out. Of course, I have never done it so far since I was always within 3 miles. ...and I can't see any reason to go through a tank at sea instead of flushing directly overboard. Oh, reason is options, and simplicity. I can sail legally in coastal waters and without problems off-shore. True, having some construction with Y-valves, or additional pumps and dip tubes would also work (and actually have some advantages), but this setup is far simpler. If the tank vent should become blocked, you'll have problems flushing the toilet due to the backpressure. Worst case would be a blocked tank vent AND a clogged overboard discharge hose at sea in 8'+. -- Peggie OK, this part I don't understand. Why would a second drain block the vent(s)?? --Ernst |

Peggy -- I think SunMar makes one that doesn't need any power, but they do
require that "excess fluid drainage" that you mention. Some of those that require power claim to be able to dry the "fluid" sufficiently not to actually use the overflow under lower usage (one or two people full-time), but they're also way too big for my boat. -- Karin Conover-Lewis Fair and Balanced since 1959 klc dot lewis at centurytel dot net "Peggie Hall" wrote in message ...
