I have a 5-year-old Worcester Bosch boiler which I have to re-pressurise almost every day. I have two questions: 1) why does the pressure drop - where does the water go? 2) have you any idea what might be wrong with my boiler that its pressure drops so often? Thanks in advance.

I've recently moved into an old house which has less aged wiring. It is a 200 year old country house which was split into three dwelling places back in the 50s. The fuse box is quite new and the cables I have seen look fine. However, occasionally the lights in the whole house will go dim...

Hello, I have a query about the combination of a fused spur and a trailing socket. Please let me know if I am mistaken in anything below. Any replies will be much appreciated. 1) A fused spur is the same as a trailing socket as far as the electrical connections are concerned. The only...

An electrical appliance at work stopped functioning the other day. We opened the plug to find that the fuse had popped. The appliance was left to one side (in the designated area for such things) and we decided to reschedule that part of the job until later in the day, while the appliance was...

Hello everyone. When wiring up six (50 Watts each) halogen downlighters, is the type of cable used important? Can you use flex? Can you use 2mm^2 cable? I guess it's all to do with current limits i.e. 6 x 50 W draws about 1.3 Amps. I don't know the limit on flex, but 1.3 Amps sounds ok...

Sorry for the topic title, but I don't know the proper name for the part. In my airing cupboard, I have a pipe going to the HW tank and another heading off to the radiators (I assume), both being fed by a pipe coming from the pump, making a T-junction. On top of this T is an electrically...

I recently laid a new wooden floor in my lounge and was amazed to find out just how far away from right angles some of my corners are. For example, measuring from a wall to one side of the door on the opposite wall, 386 cm. From the wall to the other side of the door, 383 cm. So, in the space...

Hello. I've just replaced a standard radiator in my bathroom with a (non electric) centrally heated, metal towel radiator; you know, one of those ladder type things. My central heating system is fed by plastic pipes. Elsewhere on this forum I have read that if radiators are fed by plastic...

If I were to lay cross battens (not tied into the walls) in my loft space with chipboard on top, does the cross-battening add more strength than weight, or the other way around? What is the optimum/recommended size of the cross-batten? I was thinking about 2x2, but suspect 3x2 might be...

I'm sorry for being a bit thick on this issue, but I don't want to risk breaking my house. In my loft there is currently fibreglass insulation between the 4-inch joists and just felt under the roof tiles. I plan to board out the loft floor, which will inevitably squash the insulation, reducing...

To drain the CH/HW system I get the ideas (stop water, open drain valve, open upstairs bleed valve etc...). If I wanted to drain it partially e.g. to about a foot above the pump (I have a hole in a section of pipe about 2 feet above the pump, so plan to replace that piece of pipe), does anyone...

So, from 4 out of my 10 radiators I get no heat, and I mean none. The pipe is warm up to the TRV, but the rad cold (and I've tried new TRVs). I'm not a plumber, but had a fiddle with the output valves around the system (attempting to balance it), but it made no difference and I've returned all...

Hello. I am a 30 year old physicist who is thinking of a career change. Any help, advice and suggestion you can make (whether new or experienced in the trade) would be very much appreciated. Having worked with loads of high voltage equipment in my current job and having enjoyed electrical...
