Has it been wet or dry tested? Have the loops been purged through, eg so all the air got blasted out? You’ve not answered about the cap on the bottle vent.

Nobody will ever know Let's keep it between you and I.

We shall put that typo down to nerves

Let's be sure there's an actual problem first The biggest "oops" here will be a wet test done and then somebody simply forgot to pinch off the cap on the AAV. The air in the loops then rises to the manifold rail and ejects itself, resulting in a drop in pressure. If you had a significant leak there would be zero pressure on the gauge right now.

That's the best reply any stranger can offer to a random guy on the internet at this time of night. Is the cap on the automatic air vent open or closed? It's the thing that looks like the air cap on a car tyre. Can we have a better pic of the whole manifold?

Have you closed the cap on the automatic air vent?

Split the shower cold and basin if you're going to split, as the WC will still be filling when you use the basin tap to wash your mits

Is this just to run machinery? Would it not be simpler and cheaper to swap out to single phase stuff and be grid tied?

It will work, and is the go-to solution Compression is the only way to join plastic to these 'fancy' waste / trap kits tbh. This is what I do, and the compression stuff just never leaks or fails as long as you don't use any silicone / lube etc on the joint. It is a must to put these on 'dry' and only tighten to a bit past hand-tight, then jobs a good 'un.

The bastards are using drones to survey sites to see what’s ’available’, it then gets added to their shopping lists and picked off to suit demand. Hire one for the immediate, but even then you need to make sure you aren’t responsible for replacing it if it stolen from your site whilst on hire!!

Combination overflow / filler, and wall mounted taps vs "bath taps", same as I have as I hate bath clutter. Washy crap in wall-hung corner baskets and deck of bath free from projecting toe-stubbers.

But the white does utterly transform the house!

Has nobody seen iRobot? Stop with this voodoo before the machines rise against humanity and we all become slaves! probably.

Why the joist, and not just a batten on the blocks, levelled accordingly, to save space?

I find that using compression for these things offers a far better opportunity for removing / servicing these things downstream, so no probs there at all. Happy days.

Defo stick with close-coupled. The frame will need boxing and tiling and will eat into the room for very little gain, prob be a bit uglier tbh.

Compact, short projection, space-saving, are all the common names for these things. https://www.amazon.co.uk/Affine-Bathroom-Toilet-Coupled-Cistern/dp/B07DTJS4SD?source=ps-sl-shoppingads-lpcontext&ref_=fplfs&psc=1&smid=A1UUGTWDE5YX23&gQT=1

My apologies, is the wall behind the WC a breeze block one and not a stud wall?

The extra length on the ASHP pipe 'could' be offset by bringing them indoors earlier, I guess, so they're in the heated envelope, but we're really down to a few brass tacks then and I'd rather not have the inconvenience of these pipes traversing the house interior tbh. Somethings gotta give! I have, for a project in Graven Hill, run the ashp pipes through the slab insulation (atop the lower 100mm PIR slab, then capped by another 100mm layer, then 100mm polished concrete (with UFH & mesh)) so that the losses are minimised, as the delta between the pipes and their immediate surroundings are no longer so adverse. That could be possible for you without too much effort methinks; just use 2x28mm Hep2o runs and ditch the underground duo pipe then.

If you're converting to a habitable space then the garage door is first to go in the bin. Have you thought of EPS EWI (external wall insulation) and then have a new render all round?

I was sure you just couldn't have joints buried? You'd not be pulling copper out and pulling new in?

Crane option should result in less damage / death. Really poor place to take a risk on items from chuffing Aliexpress ?! 🤦‍♂️😉 Doubt they have been through much quality control or rigorous testing…..😑 If one of those drops on to someone they’re Donald Ducked.

Either option but if the coupler is on then another damage mitigation policy imo. The sand shutter option is ridiculously cheap, quick, effective and simple. Couple of pays with the back of the shovel to compact as you go, and the concrete just bounces back away from it. Henry has been a soldier over the years, no task has beaten him yet. Same one for 20 years, just has had 40 new hoses and 6 new main units lol.

Another “high temp” split methinks. 70°C is beyond most monoblocks.

The fully compact / modular boxes are all “gas” powered I suspect, that’s how they can make it physically smaller. The conversion happens once not twice then as energy is released direct to the heat exchanger in the cylinder vs 2x conversions gas > wet then wet > wet.
