Apart from your access issue you might want to look for an aggregate recycler . Then at least he wants what you have !

Tis a true pain getting the solid pipe in place to allow for all connections

Below ground ducting complete . Think i’ll Add more support to some of the pipes . The fixing clips don’t seem especially strong . Ground floor now - should be easier . Tricky doing long pipes on your own as I have no friends ??

I am indeed the man to ask !

Well ! Its going in ! . Solid pipe is a right pain.

Just what I had lying around

BPC say that the duct seal stuff remains plyable for a few days before setting. I'll keep to CT1 for now.

Oh yes; I was going to foil tape all joints anyway. Rather make sure they aren't coming apart before I do that though...

Ah bum ! Going to try some ct1 instead !

Hmmmm perhaps i’m Not meant to use this for connecting solid pipe . Not sure where i’m Meant to use it !

Anyone else have issues with the supplied duct seal ? . Doesn’t seem to hold joints together at all ! . Thought it would be like solvent weld but it’s not . Next day with the slightest bit of strain on the joint it comes apart ...

Right bpc who have been so good - think linking the pan extraction to the mvhr is plain wrong . One as stated the seal needs to be broken to allow this and also the volume of extraction at the pan will be limited . Am I correct extraction only occurs on flushing therefore isn’t permanent? - of course they want it permanent. I think they were concerned about combining 2 different things together . So on their advice I think i’ll Leave it as is ....

Ah I’m ok . Cleverly / luckily I left enough space . So once I’ve knocked out the floor block I can build my timber frame up with no fear of touch ufh ; which is in the screed to the right . ?

So ! If I go for an extract odour cistern should the mvhr ‘boost ‘ on a toilet flush ?? I.e some way to automate that ? . Or just mvhr in normal circulation mode ok ?

@Onoff you are behind the times and should retro fit mvhr . Get with it dude - misses will understand (not) ?

Superb ! . I’ll stick some photos up anyway just so you can all see ! . But yes ; might aswell go to 120cm and have odour extraction .

This is.why I love this forum ! . Didn’t even know that was possible . As I’m installing the mvhr as we speak much appreciated ! . My issue is at 120cm i’m Over the ufh so can’t bolt the timber frame to the floor - as I mentioned photos to follow to show !!

Erm ! Ok ! So odour extract connects to mvhr ???

Thanks . Not sure 12cm will fit . The depth from timber frame until ufh is 100cm I’ll stick some photos up with dimensions so advice can be given ! . How does ‘odor’ extract work ? Fan in bog ? ??

Hmmmm , the geberit website says 80 - 110 aswell . Peters link says 14/5 .... ?

Is that simply the ‘range’ of depth it fits or does it mean depending on installation it could be 110?

Ah ! The h114 !!

Yeah we did . Tbh though when I google sigma 8cm it says for floor standing toilets only . More googling in progress ....

Yeah ; i’ll Get newer because of bits etc. Looking at sigma 8cm
