Any pics of the outside, incl above?

I also used Ob1 to temp seal around our sika roof to the MVHR ducts that went up through the roof, before they sleeved it. Worked fine for the weeks I saw it before it was sleeved over.

We were advised drinking filtered water wasn't great! Also not a fan of the taste tbh. We have filter water at both kitchen and utility taps if we were swap over to them!

Plumb toilets, kitchen and utility sink, and outside taps off unfiltered. Showers and taps off filtered. Filtered tap in garage (washing the car) Filter all hot Works like a Charm, we have a high flow Monach jobbie, works well no impact on water pressure or flow.

Yes, that's the one! I can access the installers menu as well. DHW on a timer per cheap octopus cosy tariffs, so would prefer not to delete them all to make it work.

We are about to leave for a week, and I would prefer to turn off the DHW. The system doesn't seem to have an easy way of doing this, but leaving the heating on. For shorter weeks I've just turned the temperature down to 40 degrees and left it, but as we dint run a legionnaires cycle I'd prefer not to tempt fate. I could run a manual cycle when we get back to bike the tank, but I'd prefer to just turn it off and let it go cold. Any advice? Thanks

Just do this! Very much over thinking it, this approach will work perfectly!

Even try Armaflex tape?

Wrap pipes in duct tape, slight fill of expanding foam behind them? That's gotta get you half way there?

Looks nice, and for what it's worth I much prefer that floor. I mean no disrespect, but large format white porcelain I always think is cold and tacky, and white flooring against a white kitchen cabinets would have looked very surgical! You're better off with the contrast IMP. Loving the ceiling lighting!

Pretty common on some new builds, faux style? I've seen them on multiple estates. May even serve a practical function of an awkward roof joint?

Once a year peak summer could just blast it all out with a pressure washer to hard mud? Love it! Looks brilliant. Can you post up the links?

Cherry picker?

There must be a few structure in the freehold contract? Is that being abided by? Is there not a freehold or leasehold adjudication or ombudsman?

We didn't fully spec the electrics, and the electrician utterly buggered us as a captive audience. Plan plan plan.

Forget it, you'll soon drop the shower head and had a few more to it!

Insulate any hot run pipes, especially if hot water circulating!

Looks too shallow IMO. I'm not an expert though.

Poverty end of the spectrum here... 150mm full full, still a wonderfully warm home and at £150 a month incl daily washing machine and dish washer... What's not to like!!

Rent it whilst you carry out the work... Vacate it once finish! Tidy up as you go along..... 😁

Logic being most tile adhesive has a degree of flex, as does grout... As long as the substrate is solid with no movement, any minor minor crackage is likely to be absorbed, or will show in grout (so regrout) or worse worse case... Would pop a tile(!?).. Would it? The physics of a cemfloor type floor moving enough to damage tiles doesn't line up in my mind?

No, builder was utterly confident without it. Same with our en suites, albeit it a different tiler did our family bathroom and put it in. We had the cemfloor down for a good few months before tiling though.

I'd be angling it to join the plastic below rodding point. For the sake of an extra corner bend, easier and less risky imo. IANAL Though...

We have 45sqm of tiles on of Chem floor, used for 12 months.... Touch wood no issues.

Just to help OP, context is import. You're asking a forum biased at the highest of high end Insulated homes. Expections are therefore also biased. 150mm PIR is very good, 100mm was the norm several years ago, and even less a few years before that.... Once upon a time 0.30 was deemed fine! You would benefit strongly if you can get an extra inch or two of insulation, 50mm odd of PIR probably gets you into 'it'll work fine' territory, but you will need to accept you're loosing a couple quid a day worth of efficiency on a cold days...so maybe £100 - 200 a year worth of losses vs force fitting extra insulation? Buikding houses still all comes down to compromise! Have you considered cemfloor, or other thinner screed setups? To give you an extra inch or so? Can you loose an inch with a door threshold or shallow ramp?
