In this 'renoextension' the original MDPE supply was 20mm which I had to pull out during structural works and now looking to pull back in. It's a private water supply coming in from landowner next door in 20mm MDPE (no chance to replace that all the way to source at the moment). Not noticed any issues with water pressure living in the static, but I recall reading somewhere on BH that it's probably best to opt for 22mm in the house itself (after stopcock) if there is a chance of low incoming pressure. The landowner next door rents out various commercial units units next door (so there is a potential for a drop in pressure but I haven’t noticed so far) so just want to insure myself against pressure issues. I need to get my UFH pressure tested soon, so just need a connection in the house again and may as well get it right from the very beginning. I was looking to go for 20mm MDPE to 22mm but options seemed very limited (though typically did find an option last night, typically here https://www.drainagepipe.co.uk/products/mdpe-water-pipe-fittings/mdpe-to-universal-copper-adaptor/20mm-x-15/22mm/) I can either stick with the 20mm MDPE or would it be best to replace my incoming MDPE from the boundary with 25mm? Not sure what I'm going for in terms of UVC, boiler, TS etc etc but was reading that 20mm is a safer bet (for runs to bath at least), but that will be more questions in another post. TIA
