    Actual Cable sizes

    Thank you, mwatsonxx ! But "it would be nice" if the Table I mentioned also had that column ;-)

    Actual Cable sizes

    The table at https://www.diynot.com/pages/el/el004.php is all very well, but it needs another column labelled "overall width". I have some flat cable in my loft that's 8.5 mm wide over the normal insulation, and some that is 10mm wide. What are these for ? Is the smaller a ring main, and the...

    identifying cable size by eye

    Thanks. It's ducted behind the render, then lying loose under the floorboards.

    identifying cable size by eye

    Nine months later.... for some people, it does take a while for the joke to sink in ;-) But I have the same "challenge" It's an old multi-strand twin-&-earth, red, black & green / yellow, all three cores are covered. The skin is the usual white PVC, and the overall size, measured with...

    Secondary double "glazing"

    Thanks, Jadele - but my thinking is the same as yours !

    Secondary double "glazing"

    Thank you, Ronnie. Yes, I know you can get "proper" secondary glazing - but it's expensive... :-( But thanks for the rest of your advice.

    Secondary double "glazing"

    Our house is Listed, so we can't change five of the windows. They mist up in winter - have to be wiped every day - and obviously also allow the heat to escape. The opening lights are not very draught-proof, either. Upstairs are three three-light casements, the centre light is hinged. Each...

    Cleaning old pipes when jointing

    When T-ing into old tarnished copper pipe, I have always scoured the pipe back to a bright finish for a soldered joint. But how important is this for:- a) compression fittings? and b) push-fit ? How well do they seal onto a tarnished pipe ? I have been "scouring back to bright", but am I...

    Bending radius

    Thanks ! But they don't say what radius the bend is - it looks too tight.

    Bending radius

    Thank you for that; just the job. But how tight a bend d'you reckon I could get ? 180 degrees at an inside diameter of 100mm is what I'm looking for...

    Bending radius

    I need a U-bend in 15mm copper to feed the shower hose outlet from the mixer tap (both concealed, i.e. buried behind plasterboard & tiles). The two ends need to be parallel, and 113 mm apart. Can I achieve this with my bending spring (and get it out again!), or will I have to resort to...

    Shower wall of lath-and-plaster

    The two walls forming the corner into which I am installing a shower are lath-and-plaster on stud. What should I (would you) put between the painted plaster and the tile adhesive ? a) Nothing ? b) apply that special water-proof membrane, with cement-based adhesive? c) hack off both laths...

    Light switch for shower.

    That's what I used last time.

    Light switch for shower.

    On the other hand... You ARE forced to have rectangular sockets. wall switches. FCUs. flex outlet plates. Having recently done a fair few, square is a real pain to drill out of brickwork - MUCH easier to just core-drill a round hole (which I do first anyway) - but then you have to ****...

    Light switch for shower.

    ... in your opinion. Personally. I like 'em. because ...you walk into the bathroom, and the shower is behind the door. It's 1400, the sliding door is 700, and the fixed panel is against the wall next to the bathroom door, so it would be inconvenient to use. And that wall is lath-&-plaster...

    Light switch for shower.

    Thank you for your comprehensive reply. Very useful. 1400 x 900, in the far corner of the bathroom. They are 3.5 W LED bulbs. The lights are "waterproof", i.e. the frame is covered in glass, and sealed with a rubber washer against the ceiling. Yup. Yup. Thanks for the URLs Cos there just...

    Light switch for shower.

    We've had a combi-boiler fitted, so don't need the hot-water tank. That's gone, as has the airing cupboard it was in (in the bathroom). I'm now going to install a shower in place of the airing cupboard, and inside the shower I want to install some GU10 ceiling lights - I have proper Zone-safe...
