    One thing I must stress Terry, is we are not having a go at YOU. but at least we are all in agreement your fitter has fallen short of the mark, and as Steptoe says there are shoddy workers in our trade as well, probably in all trades. It does need to be put right. That hose is the bit that worries me most and needs the proper fittings (and being a bit shorter would not hurt either) I asked for a picture earlier which seems to have opened this can of worms. That's because I was hoping for some guidance from a professional install of how it should be done, so if I chose to do mine myself I would have some guidance. Needless to say I wont follow that example. What to do? Get him back. Though if it were me, I would have the bit of paper I needed and I would now put it right myself and curse never to employ a "gas fitter" again.

    Terry, the High pressure hose is only for a changeover regulator, where the hose operates at full cylinder pressure. My "fault" count stands at 5: No 1/4 turn shut off isolator. No pressure test point (so probably no pressure test done?) Wrong fitting used to connect hose to pipe Wrong clamps at both ends of the hose No chain securing the cylinder from tipping or being pulled over.

    Mine will be an automatic changeover regulator and two bottles. I will have to check if the pressure test point is built into the changeover reg or if that is a separate fitting. From the changeover regulator, two HIGH pressure hoses connect to two gas bottles, as Jeremy says, usually bought pre made with crimped connections. The reason for an auto changeover, is a bottle of gas lasts a very long time feeding just a hob, well over a year, and I don't want to be going out in the night in the middle of winter to change it when the gas just runs out. I also seem to recall with an LPG installation, there is a requirement for a quarter turn gas shut off valve outside to turn the gas off in an emergency. That seems to be missing from Terry's install. Altogether, not much of a gas man?

    Let's see what Nick says when he sees this?

    The inside plumbing looks fine to me. It's the outside bit that bothers me. Just stretching a hose over a bit of 10mm pipe and putting a jubilee clip on. To start with there is a special type of clamp for a hose, not a jubilee clip, and second he should have used a hose nipple fitting. Secondly I am pretty sure you have to provide a fitting into which you can screw a pressure gauge to perform a leakage or "drop" test to ensure none of the pipework or joints are leaking. The absence of that suggests he has done no proper leak test. The crazy thing is BC will accept the bit of paper and not even look at it, but if I had done that, they would be all over it with a rash.

    Are you really going to tell me that was done by a gas safe "engineer" who gave you a certificate? The gas bottle connection in particular is not how it's done. And where is the pressure test point etc. I am perfectly capable of doing a simple job like plumb and LPG hob to a regulator but for the sake of getting a bit of paper I am willing to pay someone to make the two joints and issue that bit of paper, but not if he does it like that.

    I bought a load more Knauf Earthwol Frametherm 35 a few weeks back, It had gone up about 13% since thee last lot I bought in March 2016. They swore the increase happened last May and was nothing whatsoever to do with Brexit.

    So they can get a consented plot for £50K and make £38k building a house on it. Why not sell it to self builders for £100K per plot (probably cheap for the south) and forget all this house building stuff? Seriously, I can't understand why there is not a move for mass developers to sell a couple of self build plots per development. They would probably want to leave selling those until the end of the development so whatever anyone does with them won't impact the sales of their main development.

    Can I have a picture of the gas connection under the hob please (take the drawers out?) and the gas connection at the regulator? Also is that one continuous piece of pipe (annealed 10mm copper for instance) , or solid pipe with joints? If I could find someone to connect it and sign it off for £100 I would be happy.
  10. ProDave
    That's an interesting article in many ways. not the main thrust of it, but from that I glean they made £175m in 2016 from building 4000 homes. Unless my decimal points have gone astray, I make that £38,500 profit per house. Whoever blamed high prices on the builders? I presume that factored in the land cost in arriving at that profit. so after buying the land, building the houses they make just £38K per house. As I have said before, there is no money to be made in building houses at the moment.

    I also recall they didn't just screw them in place immediately, that would just have burst the screws through wet PB if it was not a tight fit. Rather they wedged it in place with battens and props to let it mould to the shape of the curve before finally screwing it once they were happy it had formed. Yes if you could replicate the curve outside and perhaps leave it lying flat on said curved former it might just curl itself into a perfect fit and be easier.
  12. ProDave
    An office I used to work in had this done, a curve around a half landing. A studwork frame was put up, in this case with steel studwork. Sheets of standard plasterboard were left outside leaning against a wall for a few days and watered regularly, and over the course of a few days took on a curve. It was then fitted to the wall while still damp and pliable enough to take the curve they wanted, then left to dry out and skimmed.

    Your incomer may look small, but it will be a concentric cable and will be 25mm or even 35mm. Put an 80A fuse in your switch fuse, or even 60A if your max demand is low enough to discriminate between the Dno's 100A fuse (and 100A is beyond the rating of 16mm SWA)
  14. ProDave
    Cat5 and phone in separate duct at least 300mm apart. In practice, you will be digging at least a 300mm wide trench so one each side before you back fill. SWA does not need a duct, use 3 core and then you have an earth core as well as the armour, and buy it from the right place and it's the correct colours. But personally I am just using the armour. You will need an 80A switch fuse to feed a 16mm SWA and check your max load and volt drop to check 16mm is okay. (mine is okay at 25 metres)
  15. ProDave
    I would not be sure about the fuse rating. We were only offered a 12KVA supply yet it has exactly the same 100A fuse as any other house in the street. The reason in our case was the number of houses sharing the same 100KVA transformer, and no doubt if we had asked for more, there would have been a capital cost to upgrade that transformer.

    Personally I can't abide rolling credit fixed monthly payments, but accept that may be the bribe you have to take to get the best deal. But are you not looking at this from the wrong angle? It's not the monthly price you need to look at, but the unit costs for the energy. Anyone could set the monthly payment low to make them look cheaper, only to find they have under estimated your usage and you get a correcting bill. Or am I being to cynical?

    I was going to nominate my pallet shed for the "reuse" category but I think OnOff has just won that one. Triassic definitely wins the best aesthetic design category.

    Another advantage of the Scottish system of sarking the entire roof with some form of solid board.
  19. ProDave
    So the Scottish regs require a continuous ventlation rate of 0.5 ACPH My kitchen / dining room is 4.8 metres by 6.8 metres and 2.4 metres tall so a volume of 78336 litres. So we need to change half of that per hour = 39168 litres per hour which works out at 10.88 litres per second for the whole kitchen which will be via at least 2 mvhr extract vents. So not much ventilation needed only 5.4 l/s per vent terminal. Plus the ability to boost at 50% (I am sure our boost will be more like 100%)

    I'm not sure I see your question yet, but I can't see why a poly tunnel can't be discussed like any other garden building. Not sure how you find the room for a poly tunnel with no garden, I presume some arrangement with the land owner?
  21. ProDave
    Doesn't that depend how many beers he's had?
  22. ProDave
    Let's turn this into a "spot the fault" I'll start with pitch leaking from the head. 951 clamp on the earth (that can crush the cable resulting in a very big bang) and a SWA cable exiting the bottom of the CU with the armour not clamped at all. EICR fail for me.

    I lost a friend and "good customer" just over a year ago to bowel cancer. It was picked up in his early 50's as part of the screening process up here for anyone over 50. He had an operation, Kemo etc then had the all clear. (at the time he kept this all quiet, all I knew was he spent a lot of time in Glasgow for a while) then 2 years ago it came back, it had spread, was inoperable and terminal. He died December 2015. In fact it was only his wife who actually told me what was "wrong" he just told me he had some "health issues"
  24. ProDave
    I am miss understanding something here, can you clarify please, are you worried about planning permission or building control sign off? I would have thought this small extension would be permitted development, so I assume it's building control you are concerned about? And since they have approved the foundations I would take that as acceptance.

    the tiny amount of DC power a router needs, connect it to a battery..
