Came across this from 2014: https://www.diynot.com/diy/threads/future-proof-oven-and-hob-circuits.417854/ Has anything changed re future proofing?

I hadn’t really thought about that but that makes sense. It’s definitely not an RCD/RCBO that trips and can be reset. I’ll need to check with the electrician. The CU is about 12 years old so I’m surprised it wasn’t done then.

Okay, so I should have been more precise. I say Consumer Unit as a collective term for the electric cupboard but what happens is that the electricity supply comes in and splits 1. to the Consumer Unit where RCBOs control the house excluding the extension, 2. to a Main Switch (on/off) from...

Running cable from the extension CU to the kitchen below would be relatively straightforward. Upgrading the current 6mm cable (or adding a second one) from where the main CU is to the extension CU would be tricky. (It’s not actually in the CU, it runs from a main switch below)

Oh dear, that's going to be a problem. Gas it is...

Thanks. So it would be okay to run 2 x 6mm cables without increasing the feed in from 6 to 10?

Thanks - could you elaborate? For example, does the 6mm supply in to the CU restrict everything out? Would that have to increase to 10mm before anything else?

Hello Later this year I plan to get a new kitchen. I currently have a gas oven and hob but was wondering about the viability of electric. The kitchen is in an extension that has a bedroom/en suite above. There’s s a 6mm supply cable (max 20m) from the main consumer unit to another CU in the...

So I've added 2 45 degree bends and the slope is okay, so thank you @denso13 On the subject of a rodding point. I plan to put one on the outside wall where the pipe turns towards the soil stack. I know it's meant to point downstream towards the soil stack, however that's only just over a...

Thank you, that’s good to know. So where they both join the swept tee, horizontally the bath waste is about 15cm longer than the basin waste but if you add in its vertical the basin edges it.

Thanks, there isn’t. By that you mean the highest point? If so, yes, I’ll put an ant-siphon trap on that Sorry, what does that mean? The bath has a 40mm trap (which came with it) and 40mm pipe. Is that inadequate?

That’s great, I’ll give that a go. As you say, it’ll also reduce the gradient. Thank you!

1.07m What about long hair? Thanks for everyone's input. If there is a blockage problem I've got the rodding eye. If there's siphoning issue I could change basin trap to an anti siphon trap. (I don't think I could do it with the bath, it comes with its own trap.) One last question...

What would be considered too steep?

I think it's about the water flowing quicker than the solids which get left behind (presumably hair) and possibly sucking out the water in the traps. Ah okay. I'd thought the maximum you could get away with was 90mm per metre. (The first couple of metres in the bathroom has the correct...

Hello I'm adding a 50mm waste from a bath/basin into a soil stack, which already has two separate shower wastes connected. The only available position for a boss strap would mean a 19cm drop over a 107cm run. I can see the regs say this is too steep, but adding a vertical drop to get a...

Thanks, I’d prefer them over screws. If the basin ever needed to come off the bolts could stay (assuming the distance between the holes is standard!)

I don’t know. Maybe a coach screw/washer? Is it that straightforward? On the screw threads or on the ceramic? Thanks fo replying.

Hello. I have a wall hung basin for an en suite and have bought a Rawlplug fixing kit (140mm x 10mm bolt). It’ll be going through tile, tile backerboard and into timber. I would have got the Fischer kit but it had a couple of negative reviews. I don’t plan to sit on it but do these kits...

Thank you, that will reduce some of the hassle!
