I have an Armitage Shanks syphonic WC (1970's vintage) which is becoming difficult to flush - I think the diaphragm in the syphon is faulty because the lever flaps around for a few goes before the flush kicks in (have tried increasing the water level in the cistern but doesn't fix it). I need to remove the syphon mechanism from the cistern to get at the diaphragm but it doesn't want to come out .
In many cisterns I've seen the syphon mechanism is a push fit into the outlet, but before I get really physical and try and wrench it out, does anyone know if the A/S Syphonic has a backnut or something below the cistern? The alternative is to completely remove the cistern to get underneath.
