Before my time. It’s in a cupboard and out of the way. It’d be too much upheaval to replace the 6mm to the Extension CU, but 10mm could go under the ground floor to the kitchen. Bit messy to get it up to the Ext CU but not out of the question. The cooker is currently gas and there’s only...

Any thoughts please? If it should all be controlled from the same CU, I can’t see any alternative than 10mm running from the main cupboard, under the floor to the kitchen, up to the bedroom CU, and then 6mm cable (or two?) back down to the kitchen.

It's the house's only kitchen. When the extension was built (before my time) it was moved there. So the electric for the extension (kitchen and bedroom above) runs off the CU in the bedroom, the supply into it comes from a 6mm cable that goes back to a separate switch in a cupboard in the old...

Sorry I don’t follow. If 10mm runs to the kitchen but not to the extension CU, surely it will have to be controlled from the main cupboard, while everything else will be from the extension CU?

Thanks - that's good point about gas and woks. So instead of trying to replace the 6mm from the main electric cupboard to the extension CU, It looks possible to run it under the ground floor to the kitchen. So my question is - should a 10mm run up to the CU and then run two 6mm cables down to...

No, that’s the hardest part. If I had to do that I’d stick to gas even though I’d rather have electric.

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?
