Bolting-up porcelain

Apr 06, 2013 7 Replies

Hi all,



I'm just in the process of bolting this new WC bowl (one of the concealed f rame-behind-wall types) to the frame through the tiled plasterboard that co nceals it and was wondering how tight it should be? The bowl weighs about 6



5lbs and is held to the wall by only two M12 bolts.

I've always been ***very*** wary about bolting up porcelain sanitary ware o n account of its total inflexibility and inclination to crack with zero war ning. There is nothing in the instructions on this aspect. How do you tell how much force to use? THanks...

Until it breaks, then a bit less.

You sound like you've been there and done that!

Naah, but I have though about it before as I've been screwing down sanitaryware.

(There's an old joke about cooking toast; "Until it smokes, then 20 seconds less.")

I guess this is one of those jobs where it's actually an *advantage* to onl y have a short, cheap, crappy spanner available! Like those hopeless things they used to give away free with mopeds for changing spark plugs. I'm inclined towards just nipping the thing up until all slack between the bowl and the wall is taken up and leaving it at that. Tighten, wiggle, tigh ten, wiggle, and so on if you get my meaning. Best get some thread locking compound to stop it coming lose again.

A sample output from Linux ddate? Looks familiar...

Not a sample, it's todays date.

By Jove, you're right. Got the same result here on my system!

Nothing to do with Jove.

All Hail Eris!
