    Date of imperial/metric changeover

    Because where I live, there are various small developments, ranging from 1870s to the present day. It would be useful to know in advance what size pipes I might encounter, and be better prepared to get the job sorted. So, up to 1970, it's imperial, and, say, from 1976 onwards it will be metric...

    Date of imperial/metric changeover

    What date, approximately, was half inch and three-quarter inch copper pipe phased out, in favour of 15mm & 22mm pipe?

    Installing a wood burner

    We just had a woodburner installed. Previous fire was a gas fire with back boiler, and chimney had a liner suitable for gas fire (thin aluminium, I think). Fitter advised pukka stainless steel liner. I deliberated about this at great length as I thought brick chimney would be OK, and save me...

    Flow and return differential

    Thanks, Paul B. Over the last couple of hours, I monitored the temp gauges. With the system running smoothly, all rooms controlling nicely, with the room stat set a degree higher than normal (to make sure the boiler kept running, and relying on the TRVs to control the temp), the flow/ret temp...

    Flow and return differential

    Sider, I think I understand what you mean, but I thought that if too much water was passing from the flow to the return via the bypass rad, then the temperature would build up until there was no differential. By forcing the water around the other 9 rads, it would lose some its heat, and thus...

    Flow and return differential

    System: Baxi 100HE (control knob set about 2/3 of max), 9 rads with Drayton TRV4 valves, plus 1 rad (in airing cupboard) on bypass loop with lockshield valves. Grunfoss pump set to position 2. Range Tribune sealed HW system. Whole lot is brand new (except boiler, which is 18 months old)...

    Pressure gauge required

    Better still, got it added to an online supplier's stock list: http://www.advancedwater.co.uk/content.aspx?page=PROD_WATTSPRESSUREGAUGE

    What rights when job cancelled?

    Brilliant reply, Softus. Thank you. I did (and still am) keeping my cool. I'd already planned to send her a 14 day reminder, and I will follow the extension to that as you suggest. The time I spend on this will, for the most part, be evenings as far as possible, and as she has got right up...

    Pressure gauge required

    Does anyone know where I can get a 16bar (minimum), bottom-entry pressure gauge? I have no problem with a 16 bar back-entry gauge, and no problem with a 10bar bottom-entry guage, but getting the two together has me beat. Can anyone help?

    What rights when job cancelled?

    Woman phones up, asks me to look at a cupboard in her kitchen. I quote her a price and agree a date 3 days later, for 1 day's work. On the basis of this, I buy materials. On the due date, I turn up and measure ready for cutting materials. I return to workshop to cut materials and cut hinge holes...

    Sticking skirting to tiles

    Never done this before, but is there anything wrong with removing skirting from bathroom, tiling down to the floor, and then putting new skirting back on top of the tiles? What's the best adhesive to use to stick skirting on to glossy tiles? I would normally use Gr*pf*l, but is this OK for...

    Velux supplier

    Velux windows seem to be sold at fixed prices wherever I try, and that's fair enough. But is there a discount Velux supplier out there somewhere that I don't know about?

    "Thing" from inside bath/shower mixer tap diverter

    Bloody brilliant, ChrisR. Thanks for that - and they're located near to where I used to live. Great.

    "Thing" from inside bath/shower mixer tap diverter

    I've got an old (1970s?) bath mixer tap/shower diverter. When you press the button on the mixer, the water comes out of the shower spray and stays in that mode until you turn off the taps, then it defaults back to the tap outlet. Inside the workings of the diverter (i.e. underneath the round...

    What type of contractor for roof windows?

    This might sound a silly question, but what type of contractor should I contact to get Velux type windows installed? Builder? Roofer? Carpenter? Local paper doesn't list 'roof window contractors', and neither does Yellow Pages (although it might help if I knew the correct generic term for...

    Accidents due to new cable colours

    Do round ones exist to go on junction boxes? Whilst it might be a requirement to post a notice at the origin of supply only, this does somewhat typify the short sightedness of those who decide on such things. Surely, additional warnings at the point where the colours change can only lead to...

    Accidents due to new cable colours

    Are there any records which show the number of accidents or fatalities that have arisen as a direct result of the introduction of the new Blue/Brown colour scheme for domestic & industrial wiring? I was fitting some new lights the other day, and the innards of some the junction boxes looked...

    Sheet saw required

    That's the Shetack variety. Not quite what I was after, but I suppose it will do half the job. It's not so versatile, as the angle between the blade and the workpiece is limited by the triangular back, and the triangular back still has a strengthening rib (like a tenon saw), so you can't bring...

    Drainpipe fall gradient

    So (and forgive the mixed units), that means, on a 4" pipe, the end of a 4m run will protrude approx. 2.5" below a 6" joist (allowing for the flanges on the connectors). I can deal with that, no problem. That means I can install a bog upstairs, bring the pipe down through my airing cupboard...
