Ok onoff I see the point of the Hep2O vs mine. So instead of using that presumably std pvc 15mm pipe cutter.. I just use my copper pipe cutter? ie these hep20 jobs don't need that specifically prior to fitting the valve on? I guess I can go to screwfix & change these metal isolators for 2 of those if so. But plastic vs solid metal heavy jobs.. over time-?

Polystyrene insulation.. this isn't polystyrene insulation tho! If you start you could very well not go in the house at all out of total fear. What about the loft insulation running over the cables? that's what the pro loft insualtors did.. what about the old stuff they put it ontop of? what about the deterioration of pvc cable ontop of treated wood? what about this, that, the other.. you could go on until you're a nervous wreck sleeping in a ditch to be safe (& then the flippin jet lands on your head).

Hi Peter, yup got a good pipe slice/ easy job. What Ive got is these https://www.screwfix.com/p/isolating-valve-15mm-2-pack/65251 as I thought to permanently put on (maybe the 2 new mixtap flex jobs connected up ready too?) with compression joints.

JSHarris, you've said your thing on this/ you are just repeating. If I am concerned about this cable, then this is my perogative, & I am not. There are FAR greater things of concern in this dreadful 20 yr old DIY disaster of a house than this, which Ive lived with for 2 yerars now! You -could- argue that a jet will land on my house, no point doing anything to it, or even sleeping in it as a jet -could- land on my house. Argue till the cows come home. I'm in a training area, its a feasable argument isn't it? But you wouldn't. Why not? bc the likelihood is so miniscule as to be negligeable. The chance of a jet landing on the house is higher than some muppet 1st plugging this plug into the socket then deciding to drill around it, 1st without checking with a tester for hidden cables, metal, or xyz. It is unconnected. When I post a photo of it connected.. then by all means pipe up with all the advice. This PB isn't even finished yet, it has to come out again so I can change abc, as the extension boxes are proving hard to source (w'out spending £8 on post). This PB is last job now. I have to crack on. Please, I need help with the new wall Im about to start, my kitchen's in a terrible state & its becoming a huge burden to live as it is. If you can help with the work I'd be very grateful as I've said many times to all who have posted helpful posts. I have asked a Q today, can you help? thx

Can anyone please help me out on the 2nd wall. I have a sink to undo 1st, obviously, which I have never done before. My theory is to add isolation valves onto the water pipes @ points I can then add the new 2x flex mixtap connectors from, so extra shut-off points in future as a bonus. So water off to cut the pipes/ add the ISO valves. But is this a sufficient-enough barrier to safely turn on water again? It'll be best part of the week for me to do the 2nd wall batten/ C'tex/ sink & worktop prep/ then PB esp tricky @ plumbing area its seems, & other water pipes to negotiate LHS up the wall.. so I can't have the water off for the whole week. And @ the 15mm pipe cut points, will there be alot of water spill to deal with? any way of stopping/ mitigating against this prior to cutting? thanks zootH

It is disconnected. You can see it is (& 99% of the time it will be too). So how, if its not plugged in, is it dangerous?!!!!! do tell me. If you can't help me with the topic of the thread, please don't post. It may not be up to your design or standard, but it is my house- not yours. thx

Thanks all for the replies- I'll go over again once Ive rethought the whole idea. As simple (a box addition) it is, its still overwhelming for me to understand how it could get built as the complexities of abc are just too much for me. Eg, if I can't establish where the road starts/ where my boundary relative to it actually is (by way of a property map I paid for which is so vague/ small as to be totally useless) & these exact boundaries are anyway are vague being wales.. then I cannot get past step 1 to even establish if I need, or even needed PP to start with. I'll have to start afresh next year- I just can't cope & feel totally lost.. not the correct place to be whatsoever to evaluate the 2nd biggest £outlay in my life. I need to be sure on what is needed, sure on the builder, & sure on the design. I currently cannot tick even one of these 3 boxes.

Hi Newhome- yes new sink + mix tap. Sink needs a flamin hole drilled, 35mm or s'thing, a major pita, so I need to do that ready before I unhook sink. What I'd planned is to turn off mains water/ cut existing 15mm pipes/ take out sink & units/ add 2 isloating valves.. so In can turn water back on for rest of house whilst sink's out of action. Is that the right idea? But then I need all steps ready/ clear re. this wall so I waste as little sink time as poss. I've never done sink waste plumbing stuff, but looks mostly placcy so hopefully easier than compression joints. I'm just thinking about the 2 tops' joining too.. the sink's top needs to slide into the other, I think. So does that mean top 1 needs to be fixed in final place beforehand?

Very much doubt it! I'm back from surgery & pondering again. The cable that's so concerning.. is not plugged in remember: it gets plugged in -only- when one thing is used outside, mower, router, or chopsaw. I just don't have skills or tools to fit an outside socket. Still no extension boxes- nowhere to buy so I'll leave this PB for last. Ok onto the 2nd wall.. What I have is a bigger window area, so how to do the outline onto the PB (RHS) once the sills done..? I'd need to train a squirrel or small gibbon to use a pencil > get in > then fk off out my kitchen. I need to unhook the sink too/ put 2 isoltating valves on.. which will be a trial to live without, so I need to carefully plan how to PB etc this wall. Its also got H/C water pipes @ LHS near microwave (along with the plumbing pipes to sink). cheers, zootH

Thanks onoff (I'm not the slightest bit concerned about the cable as 1) this is only plugged in when outside work needed, 2) this bit will be be tiled anyway 3) if anything IS shorting -totally unlikely anyway-.. it'll trip this spur's fuse) appreciate the help. I'll be back once my surgery few days over & with those extensions to hand- I might well do this pb3 last/ crack on with the other wall.

Y Thanks- look if you can't contribute with anything positive or any help just negative remarks, just don't. please.

But this idiot severed through the mains cable with his 'leccy hedge trimmer tho last month.. & nothing happened. IT just went dead, not the idiot.

Yup roger that onoff.. so just confirm will you for a muppet: you say go taper edge pb2 meets taper edge pb3? Can you see tho how much easier it would be, to use the other side of pb3? I can get a much more accurate fit most probably. is this just a no-no? Anyway look here.. closing in on codeine+beer o'clock for the week me.. one more to go!

Ok so my clamps pic is wrong then! So the clamps span across the 'rough cut' line -AFTER- its been made!? if so- bingo! I had no idea the clamped ditties weren't actually facilitating the cut s'how (then my clamp back rest-on idea to confuse matters must be total bllx then!). Right must clear head. Thanks! now I can finish it today. If I can just cut & pin pb3 on, I'll call it finished for the week. So last Q is this: which taper edge do I go with on pb3? & if LHS, how do I best mark/ get the pB's RH edge to fit the wall-? much appreciated- zootH

Sorry back to this.. is this right onoff:

Can you just help with pb3, which way to put.. the Q is valid: if I go taper L edge, it meets another taper edge of pb2 yes.. but not easy to mark the pB to get a good cut/ fit.. unlike if I go taper R edge which means I can just offer up a new pB & mark top & btm points/ cut.

Ah ok. Then I'm happy where it is.. there's nothing you could drill into near here anyway/ you can't use the studs, so you'd just never likely do so. I'll just make a note of it- it'll be fine for me.

Why is that dangerous?

Its no problem to come back to this later, maybe it'll emerge from my haze! not totally happy I'm on board just yet still.. sorry onoff! Ok pb3 (next/ last of this wall). What Ive got is a cable running to outside (an extension reel under roof in woodstore- I use nearby for one circ saw, router etc.. or lawnmower/ one thing- no major load: damn handy) which Ive tucked in the C'tex [below] > then out near the double socket to be neat, & twds LH edge of pb3 so just nip a bit away here. Is this ok? Am I going pB3 LH edge taper, RH straight cut? or taper on the other side where it meets the wall?

The principle of having help at this bid for freedom stage I understand. It would be helpful, I defo agree. I'm still not getting the difference between having the clamps on, & not. The clamps aren't clamping one piece of PB to another, so they're not keeping anything in place. Afaict they're clamping a piece of timber to the front, which I can't establish if its doing something, or just spreading the clamp point pressure. The only thing Im thinking of now, is that the backs/ the long protruding part of the clamp is being used as a rest, to keep the whole piece in place.. but that doesn't seem up to onoff standard I must admit.. that's zoothorn on codeine standard. I think I might have to go a different route! I think Ive exhausted your every explanation onoff! can you think of another way?

Understand the principle of this. but I still can't see what the clamped timber is doing exactly.. or: the cut line you refer to: has this been done already on your fag packet > then clamp over this you mean? or is it to aid the 1st rough cut? I think I'll have to come back to this, I can't afford to bodge this up. (or if anyone can shed light, or, think of another way to do these 2 cuts Id be grateful). thanks alot- zootH

Ive got the vertical cut done, so maybe this complicates the other 2 cuts I'm not sure.

Sorry onoff.. I'm still unsure what the clamp is for, I see the small square of timber, & the clamp pushing it into the front face of the pB. But I can't establish what its doing/ what it's for to aid the cut. Im sure it'll be of use (as these 2 cuts are tricky/ I'm mulling over/ weighing up how to do them.. saw 1st??) as your ideas all are.. be grateful if you could clarify! call it a codeine fug if you will!

Is a saw the best thing to make the rough cuts ~2" away from my 2x cuts across? got the sod up tho.. thank gawd..

As a straignht edge along which to make the cut?
