Hi,

Probbaly worrying over nothing - but thought it best to check.

I have a ceramic (well, I'm not sure, but it's the type that isn't iron and
isn't plastic) bog cistern.

I have set M8 stainless studding into the wall to hang it on (wall is celcon
and I do not trust plugs).

Before I finally hang it - is the china likely to object to bearing on the
sharp threads on the studs (like stress points introducing cracks - that
sort of thing...)? Normal people hang cisterns on screws so chances are the
cistern bears on the smooth shank.

The studs are a good fit in the holes so not much space to sleeve it.

That leaves filing the threads off or wrapping a bit of tape around which
will probably just cut through anyway.

Or just hanging it as is. -- Anyone think my worries are founded - I hate
it to crack and fall off 'cos it's heavy!

Ta

Tim

This isn't a close coupled bog cistern then? With close coupled most
of the weight goes through the base and down onto the pan. The
fixings are just hold it back against the wall.

Assuming the weight is being taken by the fixings, I'd be a little
concrened as well. I'd sleeve the threaded part with something.

Room to get a bit of split and trimmed plastic pipe in?

Often not fixed to the wall at all.
They usually fix firmly to the pan.

Loo cistern fixing screws have plastic shields between the metal
and the porcelain (a bit like mirror fixing screws).

I got a packet of them from Screwfix and used a couple to fix my
toilet pan to the floor ....they are a small tube with a countersunk
end and fit in the holes and the screw goes in to it ..Fischer make
them

I've come across several close coupled cistern that dont even have fixing
holes for the wall.

Does the cistern not coming with fixings/instructions?
I have a 1970s build place and the original toilets had separate pottery
cisterns.
They were mounted on an "L" shape bracket, the leg of which went up behind
the cistern IYSWIM.
So the fixing holes at the back (that you are referring to) were simply to
stop the thing tipping forward not take the weight of the cistern full of
water.
If you can do something similar (discretely) then that's what I would
recommend.
I have retained one cistern of that ilk, but boxed it in for attachment of a
back-to-wall pan.

I'd also nip the nuts up against placcy or lead washers.

Oh, its not ideal, but it should be OK.

Easy solution is to smear back end of studs with silicone, put cistern
on and screw block to wall to support it till silicone sets, then use
nuts to tigthen down.

Inbuilt rubber grommet.

Option 3 would be to enlarge the holes in the cistern, then sleeve - I'm
not sure how practical that is, but just throwing it out there for
completeness' sake :-)
