Clauding….. lol

Only if open pipe 'gravity hot' and then cold mains the other side

If it's a combi you do get pressure drops across hot > cold, but it's still classed as balanced, so all good. "Bog" has an A-B gap so water from the cistern cannot enter backwards into the system. Number of single checks required = 0. On my combi I put a TMV which does 2 x wash hand basins @46oC, as the slower run outlets get stupid hot and I can't be arsed flicking the handle of the tap left/right to get the temp spot on. Just flick to the hot, open her up, and the same temp every damn time. Happy days.

If it's a balanced system (eg UVC with control group @3bar) then no need; that is unless it is written in the manufacturers installation instructions that they do not come with any but you have to install (if necessary). https://www.screwfix.com/p/flomasta-copper-solder-ring-equal-full-crossover-15mm/96070?tc=ET2&gclsrc=aw.ds&gad_source=1&gad_campaignid=19822796606&gbraid=0AAAAAD8IdPxHKHuWc7wissg6h-4JWisF7&gclid=CjwKCAjw7p_UBhBlEiwAhpIs7xQeIdwwnDVV-N7hY0fZuKkbvp1uWTlwrjf5adZGFYo8aOuCvNHX6RoCk5oQAvD_BwE

Lol. Can you be more country specific please https://grammarreader.com/hola-or-ola/

The next time you post here you’ll need someone else to type for you, if you buy a laser from AliEx et-al. #dontdoit!!!!

Ola, Hayden. Let it all out mate, plenty of good folk / great advice available here. The vision looks nice, are you DIY’ing it all? There’s a lot to do!

Floor sockets are a very finite thing, so if an extension lead will suffice “may not even be used” then give it the 2 fingers.

Aka "life".....kids / drinks / mops etc. Easier to flick a switch vs get a sparky out to disconnect it before you can turn that bank of sockets back on again.

Some pics would help here. It may be that the hard-packing over the steel was done poorly. Hard to say without seeing this tbh.

@Spinny I'd suggest copying this to the existing thread on this 'journey', as it would have made much more sense there and have greater context. If you want to do that, I can then hide this one .

Yes, that's fine. If screwed down to a concrete floor these can rust out. Wrap the back of the box with a few layers of duct tape, and that'll be better than bare metal vs conc floor. I usually run a floor socket from a double pole FCU, so if it takes a drink you can isolate it and put the circuit back on in the interim.

15mm Hep2o, simple and effective, and way less of a ballache to terminate etc. Why go OTT?

Irrigation requires a LOT of volume of water, nowhere near enough would come from this type of plant. The person advising you is kosher, it's a "no". . Irrigation from dedicated RWH systems for these types of current circumstances would, for context, need to be 15,000-20,000L capacity to be anywhere close to being considered 'effective', as the amount of stored water needed to get from 'drought to drought' is huge.

Ask yourself why and when you'd ACTUALLY want to change these temps I doubt there's much practical / real world need to follow this route tbh.
