Insulation installers use a belt larger than their waist and put the tape through the belt so it’s always to hand and as Mr Punter says keep the backing longer when ripping the tape off. rope or wire around the waist also works.

Keep the fairy liquid for washing dishes... buy proprietary products

I have a few septic tanks that I manage, we pay about £900 to empty 2500 gallons of liquid gold. so best to ask how much locally to empty tanks as this may push you to the fixed installation if you consider running costs

Fold the Astroturf at the nearest join and dig trench , re instate. we regularly excavate , install duct and relay with little evidence of disruption

Watch out for stored water as you are a business you will need to take legionella seriously. given the hassle with bowsers etc it may be worth getting a quote for a water connection. do you have mains power on site?

With a concern at each trade interface?

Depends on availability of materials and other subcontractors and workforce motivation An unknown for us who haven’t seen the project

Why make it difficult. Stick to 230 vac leds run lighting cabling back to a central joint box if you want to automate, if not wire it as a joint box method. little bit more cable used but you can get the best of both worlds should you wish to automate at a later date

Mix up a slurry and rub it in to seal the pin holes and cover the whole cap.

What does the manufacturer say?

Don’t you denso or tape the pipe to stop any cracking/ adverse reaction to render/plaster?

As above. or have the isolator internal with appropriate signage, advising of this

Or get an inverter that limits the output to 3.68 kW and connect up the 5kW

Builders do what is easiest for them. If the manufacturer advise this is wrong tell the builder to remove it and sort it properly. clearly they need supervision throughout the build

If you aren’t going to lift the whole floor, stuffing insulation next to the radiator isn’t goi no to solve the problem

Do you plan to lift the whole floor in the room?

MAybe the designer or builder thought it might help with noise?

Sleepers?

Mould oil/release oil is available in diy shops. ive seen others use diesel?

Bolster chisel and mash hammer?

Ageee, but I said this in regards to make it easier to cable up. so if they are in the same room or in the same wall it’s a doddle with little or no disruption

I’m all for PV, and have had mine since 2011. I think you need to think about the future too, so inverter location? maybe in a plant room/garage somewhere that in the future you could add batteries or diverters and make it easy to cable up. you won’t get be able to install that size of install without prior permission if it’s grid connected So maybe worth dealing with that first

Move it to a corner of the plot that’s away from the house and then advertise on the local free sites, advising to help yourself. let the local college know they may be interested in small items to help teach newbies or the art college may stick it on a canvas and sell it back to you.

The building game will stay the same. building large amounts of poorly build homes to maximise profit shareholders and all that.
