Close Coupled fully enclosed back to wall toilet ...Fitting help

[renovation2]

I'm having 2 Close Coupled Roper Rhodes fully enclosed back to wall toilets fitted. Waste pipe coming through floor not wall so finding it nearly impossible to connect as cant see what you are doing. The first toilet we cut a trap out of the floor so we could get up underneath it...once it was checked for leaks we replaced the floor and fully covered in ply ready for bathroom floor to be fitted. The second one we done the same but the Tiler has pulled on toilet outwards to tile behind it and broke the connection. This floor is now fitted in ply and wondered if there was an easier way to connect rather than lifting all the ply to get into it again? We have got all the McAlpine concertina fittings.

An help would be greatly appreciated

Hi there the easiest way to connect your pan is by measurement measure the distance connection will be from wall and height throw away your flexi connectors and use a bent multikwik piece of 4" pipe and a straight multikwik use a block of wood between wall and bent multikwik to take the strain when pan is pushed on..brum
