What is the recommended method for running electric cables behind kitchen base units? The OSG covers cables sunk into the wall in plenty of detail and safe zones in this respect but not clipped direct. Reason I ask is we have one wall brick & plaster and the other wall stud & packed with...

Even though that is the case according to the regs, would it not be better practice to put a 20A MCB on the circuit (even if it is a ring) since the cable will only have a max rating slightly higher than 20A.

So essentially whichever way I do it ring/radial and method 102 or Ref A the max current carrying capacity of the cable is going to be either 20 or 21A for 2.5mm T&E. Since the outbuilding is small (2x2.5m) and will only have a boiler, fridge/freezer and combined washingmachine/tumble dryer -...

We have been advised by BCO to insulate a single skin outhouse up to current standards by adding 100mm insulation and board/skim. This will be done first by putting a breathable membrane against the wall held in place by 2x2 tanalised battens at 400mm centres. Then with 50mm Kingspan insulation...

We are installing 100mm of insulation to a single skin brick outhouse which will become a utility area. This will comprise of 50mm Kingspan between 2x2 treated battens and then cross battened with another 50mm of insulation. This will then be covered with plasterboard and skimmed. There will be...

The metal rings around my gas hob have become discoloured/tarnished over the years. What is the best way to clean them? Have tried a fairly aggressive oven cleaner but that turns the metal dull in colour. Not sure what type of metal it is - looks to be a cast metal of some sort.

A couple of years back we ripped up an old tarmac driveway which had disintegrated and are now ready to replace it with gravel. The surface underneath (hardcore) is suitably compact having had numerous cars/lorries drive over it since. We were looking at a 40mm Trent gravel as aesthetically...

Anyone know if this is possible since the original post ? Still haven't come across a good solution !

I have a rendered blockwork retaining wall in the garden which I build about 6 months ago. I painted it using some expensive 'self-cleaning' paint in the hope it would stay clean. Needless to say the paint has been so effective it has all flaked off and also some of the rendering has blown as...

I'm planning a play area for the kids in the back garden by covering an area of earth with bark chippings. Since I have a load of wood (logs, branches etc) from various trees I have chopped down over the years I was wondering if I could hire a chipper and create the chippings myself. I was...

When you say mortar, presumably it would be a sharp sand/cement mix and not building sand/cement ? Also what kind of strength should it be for laying on concrete 4:1 ?

I laid a new patio using Indian Sandstone late last year. Part of the patio was laid over a compacted base of sharp sand/aggregrate using a 10-1 sharp semi-dry sand/cement mix and 4-1 moist mix for pointing. This bit is ok. The other half of the patio was laid on existing concrete steps. The...

It fired up briefly with the combustion case off but went back into standby again within 5-10secs. In the meantime I contacted Ferroli technical support who thought it might be the temperature sensors on the IN/OUT flow pipes. Would appreciate a second opinion if that is a likely cause.

I've got a problem with a Ferroli Tempra 30 system boiler - approx 6 yrs old. The programmer and room stat are both calling for CH/HW but the boiler will ignite briefly (5-10secs max) and then go into standby mode (flashing green LED). Once in standby the pump will remain on but the fan will...

is that easy enough to do with a standard torch & solder soldering a brass fitting onto copper? - whats the best way to do it? Presumably I would have to strip off some of the insulation around the top.

I'm replacing my hot water cylinder and everything went to plan & no leaks apart from the top HW outlet connector. Its a 1" thread and I've got a 22mm x 1" 90 degree elbow. No matter how tight I have it or how much PTFE I use, it still leaks. The thread on the tank is starting to get a bit...
