Lavac marine head
http://www.lavac.com/
I found the website of the really great marine head installed on a racing trimaran that's visiting Charleston this week. After struggling with those cheap plastic crappers from Waste Marine all clogging and sticking plastic valves and the damned pumps that you have to keep greased....THAT STINK.... If you've never seen this toilet, or used it, or flushed it, look out for it.... The model installed on this spartan trimaran is the simplest thing I've ever seen. The seawater seacock through the hull is right behind it and there is a water loop with an anti-siphon U in the top of it because in this boat the toilet is far below the waterline and would flood the hull otherwise. There's NO PUMP, NO PARTS, NOTHING MOVING in the head, itself! The head is simply plumbed with plastic bilge pump hose to a regular Whale diaphram bilge pump surface mounted high on the bulkhead behind and to the side of it so you don't bump your head while seated. The outlet of the pump goes into the Y-valve to select sanitary tankage or overboard discharge. After the pump, it's the same old sewer system any boat has....way too small to hold much for long. You have two choices to flush.... Leave the seat OPEN and it merely pumps out whatever's in the bowl until it sucks air....LOTS OF AIR! That diaphram pump isn't that crappy little plastic pump on the head you have now...and it works SO EASY WITH SUCH A SHORT LIFTING HOSE...ABOUT 3' so the pump is ABOVE the waterline and can't backfill the boat if one of its valves is stuck open. If you want to use up your fresh water to flush with the shower head, this allows it just fine. Leave the seat CLOSED and it's a full-blown, self-flushing vacuum toilet because the seat seals to the toilet and the lid seals to the seat VERY TIGHTLY WITH A SOFT PLASTIC SEAL ON BOTH ON THE BOTTOMS. You hear a sound that sounds like one of those tankless gas station toilets flushing when you pull the big handle on the 1" water line that feeds them! This puppy flushes HARD on that much vacuum from the Whale pump! Running on 1 atmosphere of PRESSURE, 14 PSI, I don't think ANYTHING that can be sucked down that tube could EVER clog it up! Now the important part......IT SAYS SUCKED SHUT VERY TIGHTLY AFTER THE FLUSHING STOPS! The suction comes from an intake valve that won't let the toilet flow go backwards towards the seacock. As this valve, which must be a simple flapper, is on the seawater side, nothing in the toilet will clog it up and with this much pressure I cannot imagine anything from the sea stopping it from opening. To flush you need only close the lid and make TWO pumps on the Whale. Now SEALED, the toilet CANNOT SMELL UP THE BOAT! God, where was this when I used to have to stand watch downwind from the stinky heads in cruising boats?! |

Yes, Larry, I had one in a previous boat and it is just like you say but a very big disadvantage is that if there is a queue for the heads the next person is going to find the lid securely vacuumed shut until it slowly leaks its vacuum away and that takes some time. .. Sometimes people get so frustrated that they heave the lid up and then find that the sealing ring has pulled out of its groove and has to be pressed back in before it can be used again. Not always a nice job on a head that many people have used in rough sea conditions!!! |

Lavac marine toilets are made by Blakes a UK mfr whose marine toilets are considered the best in the world: http://www.blakes-lavac-taylors.co.uk/index.htm The Lavac has long been a favorite of live-aboard blue water cruisers for decades...and In the days when most of the people here were live-aboard cruisers, you'd prob'ly have been the last person here to discover it. The Lavac has never become very popular in the US among "weekend warriors" for two reasons: very limited parts availability and price--$350-$400 depending on the rate of exchange...plus, it's a bit intimidating to small children and landlubber guests compared ot pumping a piston-cylinder pump. -- 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://shop.sailboatowners.com/boat_odors/ |

@news.tiscali.it: Can a vacuum release be added to let the air in the bowl? I don't understand this vacuum problem. Just pull on the cover and it bends to leak air into the bowl. It's no problem at all on the one I used. It's not like it's sucked flat and noone can open it. There's a hissing sound when you pull on it and the vacuum is released. The idea of LEAVING IT SEALED is WELL worth any trouble opening it......THERE's NO SMELL AT ALL IF ITS SEALED SHUT! There's also no "seawater smell" wafting up when water is left in it, even shut with no vacuum on it....that's great, too! |

The Lavac has never become very popular in the US among
"weekend warriors" for two reasons: very limited parts availability and price--$350-$400 depending on the rate of exchange... Got mine at a boat jumble in Netherlands for 10 euros - but I have changed the seals. On my vessel suction pipe takes water from a small domestic cistern fed from the cold water. Also have two Lavac pinhole valves to fit to suction line, but have not yet got round to fitting them. |

Now the important part......IT SAYS SUCKED SHUT VERY TIGHTLY AFTER THE FLUSHING STOPS! The suction comes from an intake valve that won't let the toilet flow go backwards towards the seacock. As this valve, which must be a simple flapper, is on the seawater side, nothing in the toilet will clog it up and with this much pressure I cannot imagine anything from the sea stopping it from opening. To flush you need only close the lid and make TWO pumps on the Whale. Now SEALED, the toilet CANNOT SMELL UP THE BOAT! God, where was this when I used to have to stand watch downwind from the stinky heads in cruising boats?! Way too much trouble and expense when the following does the job better in every way: http://store.vernondeon.com/index.ph...&ID=17&PID=428 Only $8.95 plus shipping. Wilbur Hubbard We can buy 'em for 99p in the uk. That's probably what the vendor on this website pays for them. We're in the wrong business! Dennis. Send me a dozen, heck a gross. Thanks, Only if you pay for the air freight! Dennis |

Let's examine your fetish which is highly irrational. Take your kitchen sink, for example. Some uses of a kitchen sink include the following: washing dishes, cleaning vegetables, peeling potatoes washing your hands washing your hair washing your feet brushing your teeth dumping garbage in to be ground up by the garbage disposal washing your dog (small) pre-washing cloth diapers Now please tell me why you don't have a different kitchen sink for every different use?

Boeland wrote in news:4921bc34$0$14489$5fc30a8 @news.tiscali.it: Can a vacuum release be added to let the air in the bowl? I don't understand this vacuum problem. Just pull on the cover and it bends to leak air into the bowl. It's no problem at all on the one I used. It's not like it's sucked flat and noone can open it. There's a hissing sound when you pull on it and the vacuum is released. The idea of LEAVING IT SEALED is WELL worth any trouble opening it......THERE's NO SMELL AT ALL IF ITS SEALED SHUT! There's also no "seawater smell" wafting up when water is left in it, even shut with no vacuum on it....that's great, too! The issue is that a considerable vacuum is created while pumping. There should be a pinhole in an intake line loop to serve as a anti-siphon vacuum break. This also bleeds off the vacuum in the bowl, and allows the bowl to fill after pumping, but how fast this happens depends on how far the bowl is from the loop and the size of the hole. With no pinhole, it can be impossible for someone unfamiliar with the system to open it; as I said I can usually pry mine pretty easily but my kid can't do it within 10 minutes of a pump. |

I think about putting a little valve in the intake line, but I've never found quite the right item. |

Right, it is important that the pin hole is at the top of the intake line and that the intake is set-up so no water can collect between the pin hole and the head. If you have a sag in the intake line between the pin hole and the head it will negate the pin hole and you'll have to wait for the air to leak into the head through the water and seat seals. That seems to take minutes. With a proper set-up you you should be able to open the lid in 15 ish seconds. FWIW, I met a guy who had taken a regular home toilet and converted it to a Lavac like system by making a top that could be sealed down when the toilet seat was up. Seemed to work like a charm.
