Hi,

Just wondered, before I (finally) did it:

Is it advisable to smear something (plumbing grease or LS-X) on the rubber
washers that seal the bottom entry to the cistern to the syphon? I'm aware I
don't want to glue it in irremovably, but at the same time I'd like it not
to leak! BES sell some silicone grease for plumbing - wondered if this was
an intended application?

Ditto pan spigot to pan connector (rubber ring seal) - seem to recall using
some special grease a long time ago, but that was into an old iron pipe that
was rough.

Ditto again the flush pipe into back (had to use a load of silicone on the
old bog to stop this leaking but the rubber was a bit hardened with age).

I used silicone sealant in one case where the porcelain was too
poorly molded to make a good seal on the rubber. Otherwise I would
not have used anything.

I use a smear of ordinary soap to make assembly easier. The water
will wash it away. You don't want silicone grease because the parts
will then slide apart too easily, and possibly not stay together.

Thanks Andrew. I'll go with nothing in the first instance, save for the
lubricant (I actually have a can of silicone oil spray as I've done so manty
push fit 110mm pipes - that's pretty good. Dries off and the joints don't
slip after a while).

I always use a smear of LSX.

Silicone lubricant.

This is a low level then? Normally just use a new connector. If its close
coupled I use Plumbers Mait.
