syphonic double trap toilet.

Hi TGOR,
So are you saying that as the water flows down from the syphon in to the pan through the rim,this causes a sucking type of action and sucks air up through the tube creating a vacuum between the two traps momentarily, then releases the suction when water empties from the syphon. (sorry if i sound a bit thick on this one)

 

[TGor]

Yes that's the way it works!!

Thanks a lot TGOR.
I'll be able to drink my J.S in peace now
without trying to think that one out.

As just a simple two-dimensional electronic engineer I am now completely confused!!!!
Is there a (simple) drawing of the innards of this abomination; siphons, traps, (bombs, aspirated or otherwise) to enable an understanding of how it works?
I now have The Flushing Problem with one. The handle came off the lift plunger thingy so I had to take off the tank to get at the insides of the siphon; since then it has not worked! I have replaced the donut and clamped the tank down hard onto it but NFG. Obviously my fault but how?
Thanks....

Hi Leon,
I dont know where you can find a really good explanitory drawing.(tried myself)
Make sure the syphon diaphragm is not split/damaged.Is the cistern water level o.k. Is C link set right.
Is the bomb still on the aspirator when you refitted the cistern.(as well as the donut ring).
Screw fix site will show you what the aspirator should look like.
I was advised a new turbo syphon and aspirator/bomb makes a good job on these systems
but have not tried it myself.

Other members on this site may well be able to help you.
Good luck mate. :frown2:

Cistern water level is as before and flushing moves all the water out of the tank. Still trying to find what bombs and aspirators etc are....!
I did not see anything different when I dissassembled the tank gear and thought I had done the Hains manual thing ok; Reassembly is the reverse of dissassembly!!
Will check out ScrewFix. Thanks for the tip!

Found it! Thanks.
Can you, or anybody, tell me who makes these things?
The manufacturers might have some Special Tricks!
