OT: replacing an ancient syphon in my cistern

[FloatLeft]

I like a challenge so am going to give it a go. I'll try and replace the syphon and if I can't I'll Make a new diaphragm.
If I flood the bathroom then I'll be sure to post pics. Thanks for all the advice

Go for it.
I always fit an isolating valve on the supply pipe to the cistern, if there is room, saves time keeping turning off the water to the whole house.
Get some old towels ready.
Good luck.

I only work weekends if someone has a gun to my head or I need some extra money, the novelty of this job wore off recently.
I've had enough at 10.30 on a Monday some weeks.

How do I tell if the pan is siphonic?

Difficult to say without getting inside it, but inside the syphon is an aerator 'bomb' which helps the water flush down.

Best pic i can find is here:

The circular rubber bung goes on the end of the black stem at the bottom of syphon.

Your pan doesn't look to be one as they're a bit bigger/longer due to the extra trap. But if it is (and they are also a bit of a bugger to set up AND not made anymore i heard) then ditch it for a new set up as recommended..just not from B&Q IMO..

If just the diaphragm is torn, and you can't find new one, then simply cut a new one from a rubble sack or similar.

Otherwise those 2 part TD are great.

Good luck

Thanks for your help.

So the diaphragm can be quite flimsy then? I was thinking it had to be some kind of special rubber.

I would prefer to replace with the 2 part siphon because in future I can just remove the siphon part without taking the whole cistern off.

Cheers All!

Get a 2 part syphon, Dudley Turbo syphon, I use the adjustable one.

Looks like a Whippy ice cream inside your bog, whack a flake in there

Technical term for it!!!

Not sure about that yellow bog you have.
While it is a bit wasteful I would be tempted to just buy a whole new khazi and improve the look of your bathroom.
Fitting an isolating valve on the inlet and is a definite though, specially if you decide to go the repeated fiddling with the existing siphon route.

I don't know whose bog that is to be honest. That pic just crept in.

That was me, it was on the photobucket link from Rowdey, I was just admiring the 1970s wall tiling

This explanation and the photo link is spot on Rowdey, I don't think I have worked on a siphonic for about 2 years now.

For all the faffing about trying to get the siphon out, replacing it etc you may as we'll put a new closed coupled pan and cistern in.
