Fixing toilet cistern to pan - is silicone required

[garrymum]

Below is my toilet cistern - big dome type rubber washer over the cistern outlet. Do I need to use silicone or anything when fitting the cistern to the pan? I presume the two bolts are to fix the cistern to the pan and not to fix the cistern to the wall (with wingnuts)? Is it worth putting a bit of silicone on the two washers for the fixing bolts?

No.

Clamp down the cistern before you mark the position of the rear screws, and you won't need anything to seal the doughnut.

Correct.

Is it worth putting a bit of silicone on the two washers for the fixing bolts?

I've never had to do that.

Somehow, don't know if I have misplaced them or never received them, but, can't find the nut that goes with the above bolts!!!

What sort if nut do I need? Is it a plastic wingnut (or metal) or a normal nut and metal washer?

Could I buy a new set somewhere so I know I have the correct fittings with the bolts.

Likewise, no screws to fix the cistern to the wall. Was just going to use normal wood screws as I made sure when I built the false wall that I put a noggin at the correct height for the cistern fixing holes. Again here, I would have thought there would be some sort of protective washer / insert between the screw and the cistern?

Expect another thread tomorrow on fitting the pan to the floor as it uses these new "L" shaped brackets and screws (horizontal). Looks like I have to get the brackets in exactly the correct spot then lower the toilet down over them. Thought I could position the toilet, then place brackets in position from behind, hold then remove toilet - BUT only access is from the bottom!!!!!!!

You should use some sort of compressible washer between the screws (which should by non rusting such as brass or stainless) and the porcelain. Otherwise you might crack the cistern with the point load either when you tighten the screws or when the toilet is in use and someone is rough with the flush. I've used 3/4"tap washers when I've had no specific parts supplied but I've seen pieces of rubber sheet and pices of lead sheet too in cisterns I've worked on.

Most of the toilets I've fitted have metal wing nuts and washers to connect the pan to the cistern.
