Because you didn’t say please.... it’s a tool station link ✌️ Bingo

Tray is WAY OTT in a domestic situation, and still does not negate banding.

Banding. All round band ( plastic coated ) is what we use, or you can run cables through open web pozi-joists where the two metal webs meet at the bottom. That’s classed as safe, as in the fire brigades interpretation, as in the cables can’t fall down and entangle one of our finest in the event of a fire.

What he meant to call them was “ibox”’s. Pretty nifty bits of kit and more robust than BoJo’s plans for a swift exit.

About the size of a big shoe box for mains pressure, a bit bigger, or even two units if it’s gravity with the pump module. You can run the pipe as far as is practical, but you’ll have to extend the signal cable that goes between the remote control ( in the bathroom ) to the unit.

Ok. A digital mixer shower is a box that goes under the bath or in the attic / airing cupboard ( or ‘hot press’ if you’re a big lover of potato’s ) and takes a hot and cold feed ( can be mains pressurised with solenoids or gravity fed with pumps, all integral of said box ) and mixes both feeds into one “digitally-controlled” output. That single pipe output emerges in the bathroom as the riser rail / shower head feed. Simples. Do not confuse these with ‘mixer / power showers’ as they’re chalk and cheese.

I like the tray, and same for the glass arrangement. ?. The drain is nothing to worry about as it’s still technically a “self-cleaning” trap ( which means it’s user-serviceable ). Buy it with a credit card seems the safest bet here as the feedback isn’t great.

All you need is a good electrician / electrical contractor and this type of consideration will be in-built. I cannot believe the amount that some folk pay for such services!! Understandable in commercial applications, but a bit OTT for the average domestic client AFAIC. On my current electrical projects I have helped the clients with their lighting design to a point where their architects have commented that the end result is something they're very impressed by, both executed and proposed. Some other instance I've seen have been just ugly, and impractical, with a huge expected overspend on dimming packs / scene setting and more.

I've seen countless immersions on copper tanks etc over the years that are running off FCU's, and many have been in for donkeys years. I'm not a fan of a 20a supply feeding an immersion circuit, and would go to 16a max in most cases. The majority of issues come from poor quality hardware or poor connections, and the use of bootlace Ferrules in all that we do mitigates against such issues. To get to 253v you would need to be in a densely populated area with a lot of the occupants generating with PV, so not really relative as that would apply to everything consuming electricity at that time. If anything the grid often drops below not above the permissible voltage.

Ok, confusion reigns... Water flowing at full wallop all the way down the pipe, from the manifold to the outlet, then meets the restrictor and you can gauge the end flow rate pretty well. If you put the restriction at the source, eg the manifold, then you have a restricted flow at source and then it suffers further losses caused by the resistance of the pipe ( hydraulic dynamics iirc @PeterW ) and the number of twists and turns downstream, and that’s what I’m referring to as possibly problematic. Can be done at the manifold, but possibly a higher rated restrictor would he needed there vs one at the outlet in order to achieve the same result Now can I finish my steak?

Sorry, I'm late to this party For the SA you only need a 13a ( 3kW ) immersion supply. So a 20a MCB / RCBO in the CU, then a length of 2.5mm2 T&E to a 13a switched fused spur ( with neon so you know it's got juice going to it ) and you're done. If employing PV diversion I fit the My Energy Eddi units. With those you will need to split the feed to give the SA controller a permanent supply, via a second fused spur tee'd of the aforementioned one, with a 3a fuse, and then the Eddi sporadically throws pockets of energy at the SA as and when they become available ( from the sun popping its head up here and there ). You will only fully recharge the SA from PV if there is enough excess generation in every 24 hr period, so a bit of trial and error will ensue. Boosting of the grid will be required for the leaner times of the year. The Eddi will entertain boost, or you can fit an additional 3rd party device / manual boost to suit.

? You could introduce it at the manifold if you are happy to fit an inline coupler. Would be experimental though as it would be pre pipe resistance.

Noise. Ball valves sheer the flow of water and create a horrible 'rushing' noise, whereas fitting one of these at the outlet connection is near silent by comparison 2 different definitions; Flow regulator / attenuator Isolation valve ( rotary / screw / lever )

Nope. On or off, isolators NOT attenuators Flow restriction always at the outlet.

They become quite noisy if you do that. If you're going to strangle the flow then fit a restrictor in the outlet. Beware reducing the flow to WC's as they'll take forever to fill and get on your nerves when you flush the loo at night. edit : restrictor ( not reducer )

Permission granted......

A thing of beauty. How come the outside tap is coming off that? The O/S tap should come off either directly after, or even better, before the stopcock to the house. Tee-ing off there would be a huge drain on flow for the showers, but if it's not used much don't panic.

Zoot, you don’t fully contradict yourself, but what you say in one post does not marry up to what you state in another. A builder you cannot speak to, or instruct, for fear of them packing up and walking off site is an asshole. Simple. You sugar coat the situation, even though I’m not sure you realise you’re doing so, ( and that’s not picking fault btw I’m genuinely concerned for you here ), and the relationship is hugely unhealthy from my simple interpretation. To be clear, there is no pack mentality here, just individual members posting their thoughts / observations You started this thread to get help / feedback / relief / confidence etc and therefore you must accept what had been written as CONSTRUCTIVE, as that’s exactly what it is ok ? Fyi if I spoke to / behaved around my customers like these bullies do then I’d be out of work and rightly so. They’re not the best builders at all, and I think you’d get better builders with ease. You’re clearly a little intimidated and apprehensive to cause ripples, but you haven’t got out of the ground yet and you’ve had your third litter of kittens already! Fantastic / amazing builders wouldn’t have f.ucked up the foundation level, end of. You're being given no opportunities to discuss / interject / guide and that is fatal. Were here to help so stop biting, also the advice you’re being given is free and impartial, so take a deep breath and look at this glass as half full not half empty please. Right now this feels like taking a horse to water but no drinky-drinky. Explain that you will NOT be paying anything for the founds to be made up to the height that you indicated before work commenced. Simple, and end of ? Their fcuk up, their problem to sort. If they walk off when you state that, good bloody riddance and hello new day and new builders. Either what you’re saying isn’t the full story, or you simply cannot see you’re being bullied. Have that chat, stem the anxiety of speaking with them, and set a standard for how things are to roll forward. Have a cup of tea and a digestive biscuit before replying. ?

Just cruel..... Funny, but cruel.....

Wise words. Well, except the "Erk" bit lol. It was more the principal than the actual unit So pan on the end wall ( facing the door ) and basin on the shower wall? Have you drawn this on graph paper to see what circulation space you have left?

Something like This?

Put the sink indirectly opposite the WC ? At 1200mm it won’t be usable as a wet shower eg open ended. Just won’t happen.

With respect, most of what you have written here does not reflect such a rosey situation. It may be how it's portrayed / worded by you, but there is some writing that's on the wall here I'm afraid. Next time there is a kettle brewed maybe ask #2 to sit alone with you, away from the crowd, and discuss 'next steps' to your OWN satisfaction. You need to slow the pace between client & contractor here, and ensure you retain a voice. A loud, polite but firm voice. It sounds as if there is more momentum than clarity here. I thought you were going to have a heart attack over your concrete pour!!!!!! That wasn't in ANY humour.

B = min 1000mm A = Moot, as it isn't stopping all of the water. 300mm fixed panel would stop water getting at the corner of the floor / tray junction. In honesty, this is too small a tray to be open. Minimum tray size for 'open ended' is 1600mm AFAIC, but 1800-2000mm better. Plus then you wont need the A panel.

Just sack the prick if he says that to you. Are you under some disillusion that they're the only building team in Wales? I would stop work now and meet up with #1. If you carry on as their pet, instead of their customer, FCUK knows how the rest of the build is going to go, or more importantly what it will do to your health. As you stated, you haven't paid anything yet so a quick reminder of that wouldn't go amiss here I think. It's quite nauseating to hear how you are being talked to / treated here if I'm honest. You SERIOUSLY need to hit the reset button here and cut off the problem AT SOURCE. That means a meeting with #1 before any more work is carried out on site. If you don't stand up for yourself now then you will be almost at fault for allowing this to become business as normal. Get a handle on this now, as it will grow horns and you'll regret a lot of the decisions made, after paying for them of course. I wont say exactly what I would do to the (expletive deleted)wits who have caused you such other grief, but the dog shit would have been packed into the holes in a dozen engineering bricks...... one for each window. The one thing I cannot tolerate from anyone is them being obstinate or just plain rude. Those types soon realise what happens when an unstoppable force meets an immovable object
