With respect to earth taken from the ring main Between the wire in the rose and the earth wire at the switch.

Doing some redecorating work in a room at a friend's house, and as part of this I swapped the old cheap plastic light switch out for a nice new metal face one. I then got a complaint that they got an electric shock off the plate part of the switch. Testing it with a test screwdriver, I got a...

I'm building a pair of pillars which will be filled with concrete for strength. I'm going to need to place bolts at the top of each to attach a steel joist that will span the gap between them. I'd like to use the kind of bolt that you put in place before you pour your concrete, as I understand...

Thanks. Much appreciated. :-)

Hi, I'm currently installing a new ensuite bathroom, and want to connect to the existing soil pipe, at the same level as an existing connection on the other side. Ideally, this will involve a double branch, like this one. I understand that, in order to avoid cross flow (and potential...

The glass isn't installed yet. I've just screwed the frame into the opening so far.

Just installed a new upvc window, and am having trouble because one of the openers catches on the strike plate for the locking mechanism at the bottom when I'm closing it. There's a rather large clearance between the top strike plate and the opener, however, so it looks like the thing isn't...

Yes it will. I'd recommend hiring one of these if you've got a significant area to work on. The smaller blade fits right into the perps so you can get everything out without damaging the bricks.

I'm looking at making door openings for the first floor of my extension, and looking at how the place has been built (the wall plate for the hipped roof sits below ceiling level by some margin) it occurs to me that I'm going to have to take the opening all the way up to the top of the wall...

Don't know what the manufacturer's recommendation is, but I had 6 boards of celotex-equivalent stored outside all through this winter, one end resting inside my partially-constructed extension (which quickly turned into a swimming pool when the rain started), and the boards that got wet were...

For a simple 2-storey extension, I need joist hangers to attach my joists to traditional 1930s solid brick wall (i.e. total thickness one brick length, no cavity) at one end and cavity wall with thermalite blocks on the inner leaf at the other end. I also need to match existing floor height...

I was under the impression that standard practice is to install a preformed cavity tray over the top of cavity lintels to ensure any moisture in the cavity is directed to the outer leaf rather than either accumulating on the lintel or getting trapped behind it. But having just called around all...

That's about what I was thinking, yes. I'm assuming nailplates at regular intervals would be an appropriate way of attaching the new structure to the old? Likely to be gable masonry lateral restraint he is referring to? You will need to ask for clarification. I was refering to the standard...

I have a 1930s semi with a reasonably traditional purlin & rafter hip roof. I am extending it at the side, and have permission to convert the hip to a gable. My understanding is that it should be possible to leave the existing structure intact (it is apparently in excellent condition) and...

Thanks. The problem went away in the end, but I think I should look into a proper insulation tester for next time something like this happens.

Have now done this, with no change in the results. The two cables coming to the consumer unit tested as continuous,.so it now seems certain that the circuit is a ring.

No, the sockets are dry. I assumed initially that the problem was caused by an extension cable that was plugged into the circuit and which did get wet. I'm not really sure why it's still a problem. The circuit is all internal.

No, have merely switched off at the switch between meter and consumer unit. Pretty sure, yes. There are two live conductors at the consumer unit and all of the sockets on the circuit have two cables connected.

Yes.

A fairly standard cheap digital multimeter.
