Soil Pipe Angle Options - Advice & Help required

[Pgeddon]

ha-ha-ha, my wife is generally incredibly loud, through all holes....wait.... no, that's fair.

anyway...we had building control out to triple check the legitimacy of the options. With external being a no-go, they said option 3 or 4 would be not ideal, but passable, the rest would not be.

So we went with #3, to keep the 'acoustics' shall we say....away from what really should be the quietest room in the house!.

it really isn't hard to over come with some insulation and sound block Plaster board and I'm sure you'll have the silence and solitude you hope for.

Yeah, for an extra measure, I purchased some of the rubber sm20 panels too. They're great and only 20mm deep. So the wall 'sandwich' now is

Soundbloc 12.5mm -> SM20 -> Soundbloc 12.5mm -> Studs full of RW5 rockwool 150mm -> Moisture Resistant 12.5mm

207mm thick or so in total! and on the library side it will obviously have floor to ceiling bookcases and books too! I hope its enough, she is very loud.

Definitely a builders job he's used a mix of under ground drainage and above ground Just make sure there's no solvent weld joints onto any of the brown fittings you cannot glue those.

What's the difference in characteristics for above vs under ground?

What's the difference in characteristics for above vs under ground?

Typically underground is pp (polypropylene). Polypipe do a pvc underground range (which can be solvent welded).
Above ground is pvc.

pp is stronger and more flexible than pvc.
pp can not be solvent welded, push fit is used. This also allows for movement in the earth without damaging the pipe.
pp is environmentally friendlier than pvc. pvc contains Chlorine.

I do recall the plumber using solvent. If he has used it on the pp bits what will happen? Do I need to get that rectified now ahead of all the tiling etc?

Solvent doesn’t stick to orange so yes

I wouldn't chance it get it changed.

I asked them about it. They said they only used solvent to connect the white to white. Didn't use solvent on any of the pp pieces.

Also said below ground is fine to use above? But above ground not ok to use below.
