Fitting A Wall Hung WC

[Nickfromwales]

Toilet seats are fitted from the top with captive fittings so no need to remove the pan to change those either.

Going to need to do similar on the basin and pedestal. 

 

Is this a semi-ped basin..??

 

Basin needs its bolts into the wall, and any of the above to hold it back but do not bond the pedestal to the wall !!! it only needs to be fitted on its brackets as you have to be able to remove it.

Full height pedestal. Chunk of 6"x2" in the dwarf wall to screw to:

Just had a tally up of what Geberit  (mainly) bits I've left as I'm going to fit the wc next. 

 

 

Think I need another one of these...

 

 

Hoping it's in the box with the other Geberit WC frame!

[Nickfromwales]

I think that'll be dependant on the pan. That thing your holding, IIRC, is the bit that sits on the threaded bar to stop metal meeting porcelain. Some ( most ) pans come with captive fittings which stop that happening, and I've noticed a few frames have come with kit which ends up redundant / binned.

[Onoff]

These fixing holes in the Bernstein pan seem rather large for the plastic inserts that came with the Geberit frame?

 

Can't help thinking they should offer support all the way through the depth of the hole?

Not a bad Grohe guide?

how do you fit and tighten those nuts in-situ with that bowl?? Looks like a broken wrist is mandatory...

The Berstein pan came with a decent 19mm ratchet spanner in the box!

This is the fixing kit picture on the Bernstein eBay ad. The "top hat" inserts seem longer than what I have:

 

[Onoff]

Decided to go for it!

 

Removed the yellow bung ready to figure the flush pipe length:

 

 

Lubed the end with some silcone spray:

 

 

And inserted into the frame inside the wall. It stops hard against the shoulder on the flush pipe. Marked it:

 

 

Removed the flush pipe and inserted into the back of the flanged, rubber "stopper" that goes in the back of the pan. 

 

 

Not sure tbh whether the flanged stopper goes on the pipe end with the flange or the plain, to be cut end?

 

 

Inserted into the pan. Dry it's quite a tough push, lubed with silicone spray almost too easy and seems almost to want to pop back out:

 

 

And pushed in. Again, would the flush pipe flange be better against the rubber? Can't see it'll really matter once against the wall:

 

 

With a straight edge I note the back of the pan is pretty much flush with the rubber:

 

 

So I need to shorten my pipe by the distance from the back of the rubber to the mark I made earlier when it was pushed into the frame:

 

 

Cut:

 

 

De-burred inside with a Stanley, outside with some emery cloth and then inserted back into the rubber flange:

 

 

And pushed into the pan:

 

 

Onto the poo pipe!

 

Slip the poo pipe onto the pan:

 

 

And straight edge across the back of the pan:

 

 

Gloves on and a bucket of Dettol:

 

 

A plastic bag sandwiched between pipe and rubber helps to stop the stink from the live stack branch:

 

 

Lube the end of the poo pipe:

 

 

So out with the large yellow bung, trying not to breathe and into the bucket of Dettol. Push the poo pipe in and mark as before the face of the tiles on the pipe:

 

 

Remove the poo pipe put the yellow bung back in. Dip the end of the poo pipe into the Dettol!

 

The distance between the two marks needs to come off the end of the pipe.  It's the inside of the lhs and far right lines:

 

 

 

 

 

It was 18-20mm so. used the multi tool and a couple of bits of 3/4" MDF. De-burred inside with the Stanley and then chamfered the outside with it too.

 

 

We're here, nominally ready to fit:

 

 

@Nickfromwales, two questions if I may. Should I turn the flush pipe around so the flush pipe flange sits against the black rubber insert?

 

Secondly, should I try pushing it all on as is or put the pipes in the frame first the offer the pan up to the pipes?

 

Cheers

Made me laugh too! ? I was worried we were going to see a @pocsteresque photo of you on the bog! ? ??

[Onoff]

.....and another thing:

 

The little plastic lugs:

 

 

Looks like they want to naturally invert due to gravity. So does the ceramic seriously just rest on the M12 stud? The pan is 40mm thick where the stud passes through. The projection of the plastic bit is nowhere near that long.

With terms like "flange", "black rubber", "lube"and "insert" I'm wondering where he's gotten to!

Ahem. DependEnt. (/pedent) .

 

Since he has balls of steel, @Onoff will need three of those things.

 

Let's hope he never has an accident with all those electromagnets in his shed.

Seriously now, any thoughts on this. Pan is loose on the wall, tiles clean and everything masked up but yet to be CT1'd and tightened.

 

 

 

1) Do I let gravity do it's thing and the plastic bits hang down like this:

 

 

The pan will then sit on the stud over 50mm:

 

 

2) However.....at the moment I've done this. Seemed like a good idea at the time! Used a bit of the clear plastic stud protector. But I can see the pan would only really sit on the plastic insert an the end...point load?

 

 

3) Third option, I just spin the plastic through 180deg and the pan rests on 30mm of the clear plastic but maybe not the stud?

 

 

Worst case I take the pan off quickly and go with option 1).

 

@Nickfromwales?

Ola. 

Damn, hours in the day are getting bloody well thin. Apologies. 

Something rigid like pvc tube over the thread would be better than anything soft tbh.

Strange the pan didn’t come with captive nylon ‘sleeves’ tbh, but at the end of the day as long as metal and porcelain never meet it’ll be chips ‘n’ gravy Bob.   

The fact it’s bonded to the wall will stop movement eroding the sleeve so “carry on”. ??

Ta.  Found this off cut of 22mm twin wall tube. If I leave the clear tube on and slip it over the top it should equate to the thickness of the plastic insert:
