Hello, I'm designing a box gutter for my extension, and could do with some advice. The extension roof (shown in blue, only one pitch shown) is gabled. The extension wraps around the corner of the existing house, which has a hipped roof (shown in orange). I'm designing the box gutter and...

Hello, We are doing an extension, and the ground floor is a Forterra Jet Floor (concrete beams with polystyrene infill). The beams can only be supplied in 50mm increments, so in order to get the required span we end up with the beams projecting 40mm into the 100mm cavity at one end. Forterra...

Using a plug-in test lead. I zeroed the leads by plugging my shorted plug into one socket of a double outlet, and the test lead into the other. So I guess there was no measurable resistance between the two double sockets. They are less than a meter apart. You're correct about the decimal...

Hi John, Yes, I wondered about that. I don't know where the spur originates from yet (probably under the floor upstairs), but there aren't any unexplained FCUs in the house, so I imagine it's unfused. Not sure when the last rewire of the house was, but it's all red and black cabling, so I guess...

Hi, Yes, I zeroed the leads. These two sockets are spurred off the ring, both on the same spur. The circuit's neutral goes to an RCBO. The neutral was definitely isolated from the supply neutral when I did the test (by both the CU main switch and the DNO's isolator), but according to the...

Thanks for the replies. I'm using a Di-Log 9083P, manual says it pushes 200mA into 2 ohms on the continuity test, but maybe it's not enough to accurately trace the circuit in this way. Other possibility is that I've missed a piece of equipment on the circuit somehow. I tried opening all the CU...

Hello, I am trying to work out what order the sockets are connected in on the ring circuit in my house. I have been trying to do this by connecting the line and earth pins on a 13A plug together, plugging it into a socket (with the circuit breaker open naturally!) and then measuring the...

Hello, I'm planning to use a Cube6 suspended floor with wet UFH in my extension. They specify self levelling concrete as the structural topping. Will this give as good a final surface as liquid screed? I asked them whether liquid screed could be used instead but they just pointed me to the...

How would you scaffold in the following scenario: The one storey extension has a single pitch roof that slopes away from the house. I'm building the two storey extension, so need access to build up the common wall (arrowed) to second storey height and then do the roof. How would I...

Great - sounds like a plan. Thanks both.

Ahha, thanks, that makes sense. Next question: is there any cunning way of filling in the hole such that I get a smaller hole for the tumble dryer vent? Or do I need to brick it in completely and then hire the diamond core drill? Slightly annoying to have to fill in an existing hole and then...

Hello, There's a grating in my understairs cupboard, about 1m above ground level, that vents directly to the outside. Currently it's used as the tumble dryer vent (as it was when we bought the house) by the tumble dryer's hose being bolted to the grating and then the space around stuffed with...
