new WC

[kettle1]

probably been done to death, but i cant find it.

i have a new close coupled, push button WC going onto a newly laid concrete/screed floor. is it advisable to bed it on anything,eg; silicon?
and is it advisable to put some silicon like LSX on the two rubber bungs that are on the screws in the cistern, that hold cistern to base, and on the rubber ring that goes between the two.

Its going into a rental property and i dont fancy call backs.

many thanks.
Chris

I would screw it to the floor aslong as you know there aren't any pipes in the screed.Wouldn't bother with silicon on the rubber washers/doughnut on a new wc.

I would agree with screwing it to the concrete. I always put sililcone on the rubber washers inside the cistern but not the donought washer.

anyone that puts pipes where the wc is going to be screwed down needs shooting.

thanks for the replies.

there are no pipes under the screed. Its a freshly laid floor as the original tiles were laid on a bit of ballast and that was on the dirt. No DPM, but then the house is 112 years old.

with regards to hidden pipes, i have just spent a day fixing floorboards where a sparks had butchered them, i lifted everyone to check first that there were no pipes underneath. we wouldnt want to put a nail right through the middle of a pipe would we???? and no one on here has ever done that, have they?
