How reliable are Sealand Vacuflush's ?

When it's working, you'll know it and will be left with little doubt on its ability to handle solids. It's best to flush the stuff before the TP one, then the TP in a separate flush (or two). The combination has a habit of being the culprit in any head or toilet clogging.

Now there is a good plaque for inside the head door. "PLEASE FLUSH NO. 2 BEFORE FLUSHING TP"

As noted above, when working properly it sounds just like the head on a commercial airplane. Very obvious.

Wayne, in some of our in-house testing of prototype toilets, etc., we used medium-sized peeled bananas (don't try to flush the banana peels) to replicate #2 for test purposes. If you should get a clog, it's a lot less nasty to clean out couple of crushed bananas - plus, it smells a whole lot better.

When you step on the pedal to flush it, you should get a loud "pop" when the ball valve opens. It's loud enough to scare a small child. Then you'll hear the vacuum pump come on and run for 15 or 20 seconds.

What a marvelous idea.

Thanks Guys,

Great Banana idea...much better than the reconstituted soya bean facsimile [:-indifferent],....

I never did hear any "pop" when the peddle was pressed, and certainly the noise would not have scared anyone , so I'll guess I'll just have to wait for the dealer to look at it now.

A WHOLE lot better than "Hey Frank, get over here. We need to test another prototype!"
 
Thanks Guys,

Dealer has fixed the blockage, and says that there was a missing "O" ring at the head end, causing a loss of vacuum. (but I never heard the pump running more than it should ??)

Anyway, I'll head up to the boat this week-end and test her out ! (I'll take some extra buckets just incase)
 
An Update...blockage has been cleared by the workshop. Did 10 or so No 1. flushes and it went fine. I do get the "pop" when you press the pedal, but the vacuum seems to equalise before the bottom of the venturi has been exposed.

Next day I tested it with three sheets of sealand toilet paper (and nothing else) and it blocked up again.

My feeling is that there must be some sort of partial blockage, or collapse in the line, letting air and water thru, but no solids.
 
My guess would be a kink in the line somewhere before the vacuum tank, or a foreign object in the venturi. Turn off your water supply,flush bowl two times to get rid of any water, turn off head pump switch, flush the bowl and hold the pedal wide open--look inside at the bottom you should see the venturi-whole about 3/4 to 1 inch,use a small piece of vinyl hose that fits in side hole and see if there is any resistance. it should pass right on thru .If you feel any resistance mark the hose before you remove it and you'll know approximately how far down the line you have to look and start disassembly. Good luck

Sublimetime: You be right ! ..... there was a kink in the line.

Dealer said an elbow had been omitted at build time, and the pipe had been bent around a tight corner below the head. Elbow inserted - let's hope all is well.

Thanks for all the input !
 
Glad they found it. I this was the fix (and sounds like it is) then when you use it you will know.
 
Guys,

Problem Solved - missing elbows in waste line.

Used the boat with a number of guests extensively over the past week and all is going great...I even hear a woosh when we flush !

Thanks for all the great advice.
