    Two way switched light in the ceiling

    Hi, I'm planning to feed some new ceiling lights from power to an existing ceiling rose. The ceiling rose is dual switched -switch at the foot of the stairs, one at the top. Having had a look at the wires in the rose, all I can see is live, and two other wires, which I assume are switched live...

    Adding to a lighting circuit

    Hi, I would like to install as a single lighting solution, four LED panels with four drivers. So the load is quite low. Can I intercept a lighting circuit feed to an existing light to power them. Is there any issue with having four feeds to the drivers. If so, how can I address that and stay...

    Driveway

    Hi I have a 100m2 of driveway and footpaths to the front of my house. I had the original asphalt/tarmac surface replaced in 1995 when it would have been c. 32 years old, with a red tarmac/asphalt surface. It was laid on the existing concrete base, with proven falls. I'd guess the depth of...

    Tap tops stuck

    These tap tops are fastened by a screw, but they won't come off. All the taps need a service, but we need to get the tops off. Any tips to try? Tap the tap top with a small handle? WD40? Is it possible to get similar valves if I have to replace them? Anyone recognize the brand? Probably...

    April 2016 - new 100m2 GRP roof for £23k. Condition damp, cold and rainy, but the contractor only worked in the dry (allegedly) 2021 - Not leaking, but it now looks to be in a rare old state Can anything be done - hopefully the OSB deck is still dry. What caused this disaster? What is to...

    2m headroom rule for staircases

    I have a floor to ceiling height of 2320mm and a constraint I cannot flex on the length of staircase opening My preferred staircase design has a going of 186mm. Some of second step is covered by the ceiling, with 1950m of head room above it. So it does not meet the 2m criteria - is it black...

    Water supply pipe diameter and reducer

    The communication pipe to our pavement stopcock is being upgraded to 25mm MDPE from 15mm. That's a run of about 6m I plan to have a 15m run in 32mm MDPE to the house stopcock, done by moling. My plumber recommends 32mm over 25mm to future proof the supply pipe and minimize dynamic pressure...

    Taking the rise, tread carefully

    Have an opportunity to get a nice staircase, cheap. Floor to floor, it is 2675mm. My application is 2610mm. (it is a new staircase opening, so that I can flex) (1) Can I safely just adjust the rise on the first step from 206mm to 140cm? Would that meet building regs? (2) What if I increase...

    Remedial work on curved bath panel installation for a corner bath....

    Our bath panel was never fitted properly - but you get used to things... The photos of the panel and the gaps to the wall etc are at the opposite end from the tap end Any suggestions/ideas for trims, capping or changes that could tidy up this installation? Or how should it have been done all...

    How big is my pipe?

    Anyone familiar with how (or the options for) a supply from an old main in the road would have been provided in 1963? 1/2 inch copper? galvanized steel? Early plastic pipe? 12-15mm lead? Would be grateful for any opinions. I asked Thames Water what they knew about my mains supply. They said...

    How long to give a leak to self seal?

    I've just converted to unvented. I was warned the extra pressure might expose weaknesses in some of the (60 year old) joints and fittings - so two new float valves and new tap were needed as a direct result of the change. And, we now have a small drip (drop every two seconds), presumably from...

    Unvented: What post installation changes should I make or "If it ain't broke.."

    Should I change out all the old low pressure taps and valves after going unvented? I recently had an unvented cylinder installed. Our pressure is around 3bar and max flow rate via a water softener is c. 20l per minute. It's on the limit and one day we or the next owner's will have to bite the...

    Rebalancing between two CUs

    I have two 1991 MK consumer units, each with 12 used MCB slots. It is a big house, and when we bought it, there were three fuse boards, one for each floor. One of the MK's has loading on it for a cooker (45A MCB, 6mm T&E), an immersion heater (32A MCB, 2.5mm T&E), heat pump (45A MCB, 6mm...

    Two immersion heaters.

    I am in the process of going unvented (as we speak...). I have to use immersion heaters, and the new cylinder has two. I have one feed to the existing immersion. It is on 2.5mm2 T&E and connects to a 32A MCM on the CU. We're adding a DP isolating switch in the cylinder cupboard. Will that...

    Reusing embedded shower pipework currently connected to Mira 8 shower

    I have an old Mira 8 shower, with valve, hot and cold supply, and mixed water supply to the shower head all embedded in wall plaster and behind tiles. The valve and its connections are accessible by removing a plate, and you can see three connections, presumably 1/2" BSP? The hot and cold...

    Cramped surface mount "back box"

    I want to feed a 45A dp switch with two (feed and load) 6mm2 T&E cables fed from behind through a 25mmx25mm hole in a single skinned brick wall, using a plastic surface mount box. I've tried to use a 25mm back box, but it feels very tight when I try to close it, and makes some complaining...

    Is this correct for cooking appliances? What are the principles behind diversity calculations

    I'd be grateful for any comments on this proposed design. Is it OK from a regs viewpoint to have DP isolators downstream from the dual appliance connector? As an alternative, could I just run a new cable back and power it from the same 45A MCB (no spares on the existing CU)? I'm also curious...

    Impact of induction hob on electrics

    I'm trying to make a decision on whether switch from a gas hob to an induction hob. Specifically, I'd like to understand the electrical work required that is likely to be required and what I might need an electrician to do - if the hassle is to much, I'll leave it in the pending tray. My...

    Using a lintel, where some of it is below ground level

    I've planned a conversion of an internal garage into living space using lintels to span a 3.6m gap between walls, which is normally a building regulations compliant approach. I want to put in place floor-to-ceiling doors where the garage door currently stands. The house internal floor is c...
