Default Lubricant for plumbing fittings?

Just unscrewed the nut to take out the ceramic cartridge from my
shower mixer. I'm pretty sure the brass nut and ceramic internals
should be a single removable unit. But the nut came off and left the
whole ceramic assembly firmly fixed in the brass body of the unit. I
haven't yet tried applying force to remove the remains of the
cartridge, though finger pressure won't budge it in the least.

If it does need some welly to get it out, I'm wondering how easily the
replacement will slide into place. I guess the cartridge body needs to
be able to rotate as the integral nut is tightened. So whatever is
causing the old cartridge to resist extraction may make inserting the
new one difficult.

If it turns out there is some resistance, is it ok to use a grease,
such as Vasaline for instance, on the combined ceramic and brass
parts?

For things like this I would use a silicone grease. Don't fancy gobs of
Vaseline on my head... :-)


Thanks, I'll have a look for some silicone grease. I was also hoping
someone would comment on whether the stuck cartridge is a common
feature, with some tried and tested remedies. It all looked so simple
and straight forward in the guide.



(BTW You signature has just hyphenhyphen - needs a trailing space to
work properly.)

Hypothyroidism is a seriously debilitating condition with an insidious
onset.
Although common it frequently goes undiagnosed.

Still no good. Needs to be "-- " - what I see is "--".

(There again, that is what my own sig. looks like in your post where it
is included. What *should* happen is that the whole sig. should be
stripped when you prepare your reply. Maybe something to do with using
Google groups?)

It's a Trevi from Ideal Standard.
Here's a link to a pic of the cartridge.
