Can I ask @Nickfromwales out of interest ; why attenuate at outlet not source ? . What’s the issue ? Or is it just bad practice?

Ah ! So I have mid understood ! I assumed quite naturally they could do both I.e that was their function . Well attenuation at a outlet shouldn’t be an issue . For now i’ll Just stick ‘em all full on once ready for take off ! Boom ! - bet @Onoff took 6 months to do that bit ????

I’ll do the hot one tomorrow- too much excitement for one day !

Really ? They generate that much noise if not fully open or fully closed ? . That was one of my reasons for choosing these nice expensive brass manifolds - thinking I could be clever and control flow ?

Well it ain’t pretty but timber allows a Hep2o clip per pipe . Going under the render board ‘lines’ the pipe up to run across the ceiling . Not sure how good this will be really . Need to run a ‘ real’ pipe and see ...

Actually I could ‘throttle’ the outside tap ( planned to do this on toilets anyway ) by adjusting the isolator value to restrict flow .

Didn’t think of that . Outside tap will hardly ever be used so i’ll Let it go ?

Labelling to my hearts content !

Just done my 16 vertical holes . Ordered washing machine waste to act as conduit . Just making up the manifold . Photos later

Not sure where someone like you would pick up such ‘tricks’ . 4 25mm holes drilled . 16 to go

Yep I checked this as it was an option for me . Vertical or horizontal no issue .

I am aren’t I !!

Will have a suspended ceiling .

Googling seems to range from 16mm to 20mm . If that’s correct would be good !

What’s the diameter of a dishwasher waste pipe ? . Just bought a 25mm drill bit - so if it fits in that ( and Hep2o in dishwasher pipe ) then perfect !

Not sure. Ordered a few 'cold bends' to see. Sure they will come in useful somewhere!

I could. But I've got about 20 pipes to get through this wall. Thought it would be easier going vertical through the wall then up. Also I can line up each pipe to the manifold so it runs horizontal into it. I'll attempt a "1st go" tomorrow and post pics. I'm guessing as I have a false ceiling the pipe might 'naturally' curved ok at that point.

Please. Will the scale model take 4 years also? ?

From my other thread...

Yeah - that’s why I was making the hole larger so perhaps I can put some kind of sleeve around it .

Yeah I guess so . Still a tight turn at the ceiling - but a good point !

Erk no ! Got a geberit pan going on the end wall already . i’ll just do a 1000 x 1000 or similar door’d Cubicle for the shower .

Ok . Got some 15mm Hep2o tested its ‘bendability ‘ - kinks quite easy . I need to get it through a 200mm solid wall - bend to run up it the bend at the ceiling . I see these ‘cold formers’ would that do what I need ? ( 1 at each bend ) . Desperately trying to avoid any joints . Plan was maybe to drill a 20mm hole through wall so 15mm Hep2o has wiggle room . Perhaps that former goes half in the wall ??

Sorry ; not drawn in the bath - this is on the wall opposite the sink . Easiest option is a cubicle . What I do want then is as minimalist as possible .

Would of told him to F off ages ago . Builders hate it when you remind them YOU are the boss .
