Fixing toilet pan to floor with pipes underneath - suggestions

[transam]

Stuck loads of pans down with mastic or ct1 or what ever u call. It

In fact I very rarely screw pans down

Stand the pan on the floor run the ct around it

Make a neat job of it

Jobs a good un

I must admit that I used to use silicone but I've had too many callbacks with heavier people managing to burst pans away from the floor. People will naturally move about on a toilet pan and after a while the pan can move. I will always find a way to screw a pan down now.
