Hi Guys. I am installing a new bathroom with the help of a young plumber. The toilet is a back to wall with a concealed cistern. The box it came in say's "VAIL". My problem is the flush connection in the toilet seems too small. It measures approx 50mm dia tapering down to approx less than 40mm dia. The Rubber Bush just pops out!! The flush pipe supplied is 50mm dia (for connection to the cistern) and 47 ish dia (for connection to the Bowl). I spent yesterday and today, touring the diy sheds for a smaller bush and a different flush pipe, with no luck.
I emailed the supplier and got this back.......... The TC concealed cistern has standard fittings known as "common parts". You always will require adapting the WC units to suit. In some instances you may require to fix a timber baton to the rear of the unit and then fix the cistern to the timber. We sell hundreds of these products and have never come across a problem with the parts not fitting.
What am I missing.
Regards Baz
