My go to ICF (and raft) installer bought his own props / staging etc as, as said, the costs are then reduced if you can buy these and just absorb the purchase cost over the volume of work they’ll lend themselves to. If you have that ethos then you can reduce your costs and the impact of hire etc to the client, making you more attractive / cost-effective. It also tells someone that this chap is so busy he has been able to warrant purchasing this stuff outright, and busy often means you’re good / reputable. Not always, before antibody says it, but the cost of moving and storing that stuff between projects defo makes it extremely uneconomical to own. Also, either not, or just minimally, advertising, speaks volumes (where both he and I are so busy we don’t really need to). Another big overhead that doesn’t need to be input in your overheads / profit / pricing to the client 👌

If tiling then yes, screws every 150/200mm minimum afaic.

You just need to remove some plasterboard and alter the hot and cold feeds so they come out inside the boxing in, as I’d not want to see them on the surface as that would look 💩. The waste pipe will have plenty of fall etc, so just put a 90° bend on it in the corner, as low as possible, and then clip a new run along the wall so it can come out under the same line as the taps. If you need to break some screed there to expose more pipe in the corner then that’ll be covered by the boxing in so is not a problem. You’ll need the bath in the room now with the legs set at the desired height, so you can see how and where the twos will be mounted, as a picture is much better than any idea. Would be a shame to do the prep and then the twos just look too close / far away / high / low etc. Are you employing a plumber for this?

Hi. Please post them here as there will be far more input 😊👍. My pm inbox is like Piccadilly Circus 🎪.

Full PP after 9m2 iirc.

This type of separation has been commonplace since the concept of a DPC/M came about. A nonsense statement afaic.

Yup. They do it as a knee-jerk iirc.

Waste plumbing and hot & cold feeds are very particular with a freestanding bath, so do you have some pics of the one you’re considering installing?

Hi. The pressure gauge will be isolated from the heating circuit if you isolate both the flow and return under the boiler, so you’ll not be able to tell where pressure is being lost unless it’s from the boiler itself. Is this a new boiler on existing rads and pipework? I would just top up again and monitor and wait for your chap to attend, Vaillant won’t be able to advise much better over the phone as they didn’t install it. If it’s a replacement boiler then it’s likely there’s a leak where you can’t see it, so this may need some thorough investigation to establish what’s wrong. There will be a blow off pipe, usually 15mm copper, going to the outside of the wall behind the boiler. You can check to see if the blow off (PRV) is opening and letting water out (passing) as that could have failed early. I wouldn’t interfere with the valves under the boiler as your installer may then try to blame you for misadventure etc. Best to just top up and wait for your chap tbh. Oh, and absolutely DO NOT use the hot water with the heating isolated. The boiler will perform an overrun cycle to dissipate heat and you’ll be preventing that from happening.

Hi Peter. Yup, loads of advice and info here on ground works so just choose the correct sub forum to post your questions in, and also read through some of the many posts here to see if that gets you some answers. 👍.

Yes, but offset to allow the trap and connectors / flexi, so about 400mm away from the ‘hole’ in the tray. Impey wastes can drop into a 110mm fitting, very nice, but needs meticulous planning.

Google translate may help lol https://www.naturanum.de/steico-universal-unterdeck-und-wandbauplatte?srsltid=AfmBOoql92NadyXa-HswXA3NyrDmhuB_LFO4Xh6xxaI7B5sBIZmiSGaX

Have you got a magnetic filter in the return pipework at the boiler?

That would be a brave move, plus would see the isolations behind the copper pipes? Disturbing that lot will need confidence and competence, so your call matey! Anything can be done, but my option is of course reliant on you being able to lift the pipes vertically around 30-40mm. These can be used if there’s zero movement above or below, or you go “gigantic ball’s” and do as you suggest. Better to wait until May the 4th to do it. 🙏

Whatever size the pipes are obvs!
