Hi can these be done ( pipe work in loft con )
1
waste pipe from shower run towards soil pipe. T into same pipe for Sink ( fit anti vac bottle trap to sink ) then into Soil pipe ( 40 mm for both or reduce 32 for sink )

2
I'm having an unvented Cylinder ( poss Mega flo or Santon )
And New cond Boiler in the loft
I've seen these
hotun dry trap solution for large unvented water heaters - RA Tech UK Ltd
So one for Cylinder and one for boiler but combine then under the floor then into stack therefore to minimise the pipe runs
Ps im just seeing if can be done before getting quotes for work
Thanks

1 I would run a 2" line if you can and reduce it down using a t 11/4 out the top for the basin and 11/2 through for the shower tray

2 they can't take the flow from an unvented cylinder even tho they say they can, these can

TESLATUN - Dry Trap Tundish | Tesla (UK) Ltd

Better product

ok so 2" then T off 1 -1/4 and 1-1/2 ( still need antivac ? )

Use Teslatun for both ( but can they be combined / T,d into one under floor and into soil pipe )
 
1 yes best to have one on the basin

2 yes aslong as it high temp plastic (e.g. Push fit waste pipe etc) you can put the condense in there as well (no tundish)

Needs to be high temp solvent waste but yes not as easy to get hold of

Think someone is going to do this job themselves!
Just trust your installer,

Probably going to put in new soil pipe just wanted to see what was needed / achievable for the rest I've gone from keeping my vented System ( earlier post ) to changing ( rightly so advised ) to an unvented ....... it's all new
