    External light powered from ring main

    I need to install an exterior light with switch. The location has no internal lighting circuit anywhere near it, however, there is an internal ring main that I could take a spur from on the other side of the wall from the required position. Is it permissible to take a spur via an FCU for the...

    Stuck in the middle - 16th to 17th editions - Opinions?

    I did notify BC as part of the notification for the extension as a whole and then had a long chat with the local chief BC inspector about it. It was his surprisingly pragmatic approach (for a civil servant) to this whole subject that gave me renewed confidence to take on the work myself - the...

    Stuck in the middle - 16th to 17th editions - Opinions?

    Yes, it's an isolating type and it makes perfect sense for there to be no FCU necessary on the outside of the bathroom for it. Just making sure that this known unknown, became a known known. As for the unknown unknowns, I'm working on it! Good old Mr Rumsfeld, if only everything in life was...

    Stuck in the middle - 16th to 17th editions - Opinions?

    Thanks Ban and Sunsno, your comments help. I will continue to keep the RCD only for the ring circuits that are likely to be used for outside devices as per the existing regs. Either that or leave lots of torches lying around the house... Now, about that shaver socket - any problem to...

    Stuck in the middle - 16th to 17th editions - Opinions?

    Thanks securespark, your comment about not mixing the two regs helps me. I will stick with 16th. As for Click-Sure, your comment doesn't help - and yes you do sound condecending [sic]. I am doing my utmost to carry out an installation in line with regulations and I will get it properly tested...

    Stuck in the middle - 16th to 17th editions - Opinions?

    Opinions please - Soil and waste design

    Thanks Softus, I appreciate your advice. One other thing, would you suggest going for push fit or solvent on the waste side of things? I'm pretty sure that I'll opt for push fit on the soil stuff, but (after having experienced a basin waste coming apart and flooding the kitchen) I'm...

    Opinions please - Soil and waste design

    I could desperately do with some help in finalising a new soil and waste arrangement for a domestic extension. I need to get two bathrooms into a single exernal stack. The bathrooms are side by side - the stack is on the far side of one of them. Bathroom 1 has a WC, bath, shower and basin...

    New multiple soil and waste connections

    I am in the midst of planning the soil and waste connections for two bathrooms which are back to back. The soil stack is at the side of one bathroom (BR1). The other bathroom (BR2) is separated from that soil stack by just over three metres - across the width of BR1. I need to run two WCs...

    Plumbing - Central heating extension and rising main query

    Thanks Tony, I do understand about the separate loops, pumps, valves and controls for the UFH, but can you give any tips on achieving the proper balancing of the various items connected to the 22mm loop? Regarding the rising main query, is it worth feeding 22mm pipe the ten metres or so...

    Plumbing - Central heating extension and rising main query

    I am about to begin plumbing an extension and could do with a bit of advice on two points: 1) The existing central heating is an 8/10mm microbore system running to all radiators from a single manifold, which is fed from the boiler by 22mm pipe. I have replaced and re-sited the boiler (W/Bosch...
