I am installing a timer fan and therefore need to wire it via a light rose with a switched live. However, the light in question (and the rest of the lights in the house for that matter) uses the neutral as the switch wire. Am I right to assume that I need to change this junction around so...

I am replacing the HW cylinder. The connections for the coil in and out are both 1" to 28mm elbow. My question is, how do I make these connections sufficietly tight whilst ensuring they ae pointing in exactly the right direction for the existing pipe? Are several wraps of PTFE tape...

Sorry this may sound a petty question but I'm getting paranoid about when the inspector calls! I've slightly overestimated the depth of some of my metal boxes and when the walls are skimmed (double layer of p/b) they will be around 4or 5 mm below flush level. Does this matter? Thanks, Bob

I understood that we were under no obligation to change existing installations to meet current regs, but wonder how the following fits in: The council appointed inspector says that I cannot connect the earth wire from the new wiring in new en-suite (not a new circuit, just a JB from existing...

I am creating an en-suite in the main bedroom. The first layer of plasterboard is fixed to the studs with dry-lining screws. I would like to stick the second layer on so that I can dry finish it. Is it acceptable to use a "no-nails" type bonder from a tube and gun, rather than mess about...

The instructions for my mixer shower say that I should install "unrestricted isolating valves" for the hot and cold feeds. This seems to suggest gate valves which do not narrow the bore of the pipe, as opposed to ball valves which significantly reduce the bore. Is this overkill, and does...

The instructions on my mixer shower (for my gravity fed system) say that I should take the feed directly from the cold water storage tank Would you guys actually make a new connection into a storage tank to install a new mixer shower? If not, can I assume that: a) I would be daft to tee...

I am installing an electric towel rail in my new en-suite which is IP54 rated. The thermostatic element included is one of these http://www.geyser.co.uk/element-thermostatic-600watt-matt-grey-finish-p-394.html I can't seem to get a response from the supplier to confirm that the whole rail...

I'd be very grateful for a little advice on what I think is a fairly simple bonding question. My new partitioned en-suite will have: Heated towel rail (zone 2 compliant) Shaver-point and light Fan (nowhere near zone 2) Double insulated down-lighters (no earth) Plastic pipes...

One of our showers is a mixer, HW from tank. Conventional boiler. The other is in the Granny flat (garage conversion) and is electric 8.5kw. I am planning a third to go in a bedroom en-suite. Would it be best to go for a mixer or an electric? The CU has a rating of 100A, it does not have a...

Does anyone know how having a shower set up as per a "wetroom" would affect the parameters of the relevant zones 1, 2 and 3? That is, a tiled floor sloping to a floor drain, possibly with a shower curtain around the shower area, but without enclosure or tray. I would like to install a...

New 8.5kW shower, about 18m from CU. Cable mostly surface mounted. I know that 10mm cable would be a sound bet, but it's expensive and more tricky to work with. Is 6mm safe and acceptable? The CU was new this year, therefore up to date. Is a slot in 40A MCB safe and acceptable or should...

My eight year old uPVC windows have started making whistling/piping noises when the wind is in certain directions. I have tried isolating gaps/seals etc but haven't found the problem. Any ideas most gratefully received, thanks.

Boiler idle over summer. Drained, rad valves added (by me), boiler serviced and re-set (by Corgi chap). This is an old pumped CH, gravity HW system. After intitially having difficulty getting the HW to gravitate properly (prob air block) it now prefers to travel the wrong way, leaving the...

I am in the process of re-filling my system and as in the past it is taking ages to fill. The system is old, about 1960, iron pipes, but still in good condition. The CH is pumped and the HW is gravity. The ground floor is now full after several hours, but upstairs generally takes 3 or 4...
