    Soldering copper next to a fitting

    I managed to solder it. Soaked a rag and wrapped it around. It did get slightly warm even under the rag but not super hot and the plastic seems to have survived

    NPT & BSP Question

    I have a ceiling mounted shower arm that comes with a G1/2" connection for shower head and the other end is a NPT male 1/2" but is supplied with a BSP 1/2" male to NPT 1/2" female adaptor. But it does not mention which side of the arm itself is the NPT side and which side is the G1/2" side. Is...

    Solderable wall-plate-elbow

    Will this work, isn't it essentially the same thing just use ptfe or loctite 55 on the threads (just wondering why everywhere that sells it refers to it as for garden taps)

    2-gang light switch - how to make one circuit switch on the other?

    I think I understand the diagram. This is what it does in practice: Ambient switch ON → Ambient and downlights come ON ❌ Downlight switch ON → Downlights and ambient come ON ✔ Either switch OFF → Both go OFF So it effectively makes both switches control the same combined circuit. What I need...

    2-gang light switch - how to make one circuit switch on the other?

    what about using a AC relay and putting the relay into a enclosure. something like below maybe

    2-gang light switch - how to make one circuit switch on the other?

    I’ve thought through the looping idea but I don’t think a simple loop will work for what I need. The wiring is currently as follows on one plate: Permanent live into COM of the downlight switch COM of downlight switch looped to COM of ambient switch L1 of downlight switch to downlights L1 of...

    2-gang light switch - how to make one circuit switch on the other?

    I will try and get a picture later this evening. it's quite hard to picture as it's a very tight location but will try otherwise will try and draw the layout. I do have a multi-meter and know how to use it yes. Both of the light circuits are using the same live but they just have two different...

    2-gang light switch - how to make one circuit switch on the other?

    I have a 2-gang light switch on one plate, each gang controlling a separate lighting circuit: 1. Downlights 2. Ambient LEDs Both circuits are separate, but I want it so that: Ambient lights can be switched on by themselves When I turn ON the downlights, the ambient circuit also turns ON if it...

    Soldering copper next to a fitting

    Photo below. I don’t believe the plastic green thing is removable. How wet should the rag be? Or just damp/moist?

    Soldering copper next to a fitting

    I need to solder a 15mm copper 90 degree bend about 11 to 12cm away from the fitting which contains some plastic materials too. I the soldering fire mat which has been great but for this particular solder I’m more concerned that because it’s relatively close to the fitting that the heat will...

    Wire gauge for low power transformer

    From what I’ve read, the confusion comes from “Class 2” meaning different things. In this case it’s Class 2 in the power-limited sense, not Class II (double-insulated). A Class 2 power unit just means the output is limited to a low voltage and low power level that’s considered inherently safe...

    Possible to extend wire to shaver socket?

    Any suggestions or examples of what is a maintenance-free junction box? What cable should I use? 2.5mm twin and earth?

    Possible to extend wire to shaver socket?

    I need to move a shaver socket in my bathroom which is in a stud cavity. But the wire falls about 50cm short. Is there a way to extend this? I have the cavity open at the moment and hasn’t been backer boarded yet.

    Wire gauge for low power transformer

    So put the entire thing in an enclosure maybe like this? https://www.toolstation.com/ip55-junction-box/p70316 And make sure the transformer itself and the connections are all inside the box ?

    Wire gauge for low power transformer

    I have the following transformer (pictured below) which is for an infrared touchless toilet flush system. It’s input power draw seems relatively low. I have a storage cupboard outside the bathroom with a fused spur that has supply but hasn’t got anything connected for the load. It was put there...

    110mm stack rubber seal

    I understand what you mean. I’ve got one of those soil pipes with flared end and ring that have gasket too. But I also bought a brand new T stack. The soil pipe with the flared opening and ring in it has what you are talking about and the seal isn’t removable. But the Tee stack is 100% not like...

    110mm stack rubber seal

    I have a 110mm soil stack that has rubber rings inside where the soil pipe enters it as pictured below. I’m wondering since I’ve remove the pipe that enters it a few times and the rubber is about 15 years old can these rubber rings be changed in their own? The rubber ring does come out. It’s...
