Hi guys, I've recently had a boiler repair (https://www.diynot.com/diy/threads/leaking-potterton-promax-he.495649/#post-4069085) It was a leaking O-Ring on the flow switch. BUT, the Baxi repair guy unfortunately flooded the kitchen, boiler, and himself while draining the system, which...

Hi Guys, I've had a leaking boiler for a while, but could never see anything damp on the boiler itself, just a puddle on the kitchen worktop after the boiler hadn't been in use for a while. I think it must be getting worse now, as there is a small, continuous leak quite regular now. I presume...

Hi guys, I moved in to a new (to me) house not so long ago, and have had a bit of an issue recently. When the heating (it seems) has been off for a while, when the boiler fires back up, there is a small puddle of water under it, but that is the only time it leaks, and has just started doing...

Hi Guys, I'm going to phone Potterton tomorrow morning to try to get an engineer to to try to repair this, but in the mean time, could any one offer any advice please, as my house is freezing, and I've got a baby to try to keep warm. The heating and hot water has been working fine all day, but...

Hi Guys, At work, we have had 8 car chargers installed by contractors - they've been and gone, but I was wondering about the earthing of them. (I'm not involved in contractors, so cannot ask them). What they have done is: MCB - RCD - Isolator - ran the cables outside on cable tray - then...

Hi Guys, Just moved in to a new house, which has a small shed and old dog kennel at the bottom of the garden. I'd like to pull this down, and install a new 10x8 shed. Obviously they're quite expensive, so I thought about building my own!? There is a concrete hard standing to work on, but is...

Hi Guys, I've just moved in to a new house, and when viewing noticed there was a power feed to the shed, which I thought was an added bonus. Now I'm in, and investigating things, there was actually no power in the shed. The SWA is clipped to the fence, and goes to a junction box on the...

Hi Guys, Just moved in to a new house (built 2003), which was built by barratts, so obviously the quality isn't very good. The floor at the bottom of the bed and the floor adjacent in the small bedroom creak like hell, to the point it disturbs our new born! I've lifted the newly laid carpet...

Hi Guys, Hoping someone can offer some advice. I live in a top floor flat, which incorporates some sloped ceilings as it is in the roof, and on a night in bed, for the past couple of nights I have notice a tapping sound coming from a specific area in the bedroom, which is near a sloping wooden...

I was looking through some old factory wiring schematics, where I have started a new job, and don't quite understand them (still an apprentice), and the guys here don't have an answer, so I'm hoping someone here might be able to? There is an old ring main ran around most of the building in...

Hi, Is it possible to buy and retro fit a type of inspection hatch for a plastic 5" (may be 4") pipe? I thought they were readily available, but I cannot seem to find them anywhere online. I need the hatch cutout to be big enough to put a hand in to it. Any pointers would be much...

Where can you find Type A RCBOs rather than Type AC? Just I want to install a car charger, which has a build in RCD itself, but I believe that will be on the secondary side of the transformer, so obviously I need one from the DB. It needs to be a Merlin Gerin/Schneider/Moeller to fit in...

Can someone confirm please. If mixing new conductor colours, Brown, Black, Grey, Blue, with old conductor colours, Red, Yellow, Blue, Black, It says in Appendix 7, Page 407 of the book I have that: "unambigous identification is required at the interface. Cores should be marked as follows"...

Hi, Could you help with the following diagram please? Which would be best, a ring or radical circuit? I think ring due to the length. Also, when trying to calculate the cable size online I come out at 10mm. Is that really correct? I'd have thought 2.5mm like normal circuits, but I...

We had a contractor in at work, as no one here is qualified to install what we wanted, but is it correct? We have a new machine coming, which uses 64A, so purchased a 125A interlocked switch. The contractor has done the following: Tap-Off-Box from Bus Bar, with 125A fuses -> 35mm^2 SWA...

Hi, Can anyone recommend a cheap(ish) machine to make cable markers? Not sticky lable type though, more something like this: http://www.expresselectrical.co.uk/part.asp?Part=PP-PM07507 Sticky labels and written ones don't seem to last in the wet environment that they are needed in, and...

Hi, I'm a little confused with something and hopefully you guys will be able to help. I have been given a little project to do, but I am confused by this wiring diagram: I have a: PT100 sensor 4-20mA transmitter Digital Display (temperature) From the above circuit diagram, I...

Could someone help me with what the name plates actually mean on a motor. The one I'm most familiar with is: Star: 380-415V, 0.71A, 0.25kW As all the motors I've seen are 3 phase and are wired in star. Like this, pretty standard I assume: But, the names plates also have a single...

Is there a BEST paint for metal pipework, which is fully open to the elements, and goes from cold temperatures of around zero ° C to around 150 ° C? We have some pipework which all the paint is flaking off, so I guess we need to scrap as much paint off as possible, then treat it with some...

I've been left puzzled by what someone has told me, and I'm hoping someone can help me out with an explaination. If a 3-Phase motor has a name plate with: 415v, 20A in Star, and it was running with nothing attached to it, I.e no shaft etc. Will it be running at 20A? Just someone today told...
