    Flux residue inside new copper pipes

    I’m remodelling my bathroom, which involves a fair bit of new copper pipework and a layout change. To do this, I brought the hot and cold supplies to a central point and temporarily capped them with JG Speedfit end stops. Over the past 1–2 weeks I’ve been slowly soldering all the new pipe runs...

    Stopcock weeping

    My home was a newbuild around 15ish years now and under the kitchen sink is one of those brass stopcocks labelled main water stopcock. It’s been fine all these years but recently I had to turned the water supply off and on a few times to do some bathroom work. Since then I’ve noticed that the...

    Inline bathroom extraction ceiling vent locations

    My previous extractor fan that I’m replacing was wired with Live as the supply from an outside extractor isolator switch and the switched live was from the switched light Live. So if I turned on the isolator the fan would be running on low speed unless I turned on the light switch which powered...

    Inline bathroom extraction ceiling vent locations

    I have purchased a Manrose 100mm In-Line Mixed Flow Extractor Fan and a ceiling vent that will hook up to this. I’ve currently placed the vent itself directly above the shower area where the steam starts. The extractor fan itself is in the loft and the run to the extraction point is relatively...

    NPT & BSP Question

    One side of the arm has considerably lot more threads than the other. The shower head itself that has the G1/2" connection is much shallower in terms of how many threads it has and seems to match more the end of the arm that has the lesser number of threads. And the other side has a lot more...

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

    Thank you for this. The switch i have is pictured below and i've tried to replicate your above drawing to the real switch picture below. Is this correct below or does L1 and L2 config need to be changed? Thank you again.

    15mm to 1/2 Male Spigot

    Can I use a JG 15mm push fit end cap on the 15mm end of this following product: https://www.toolstation.com/hep2o-male-adaptor-brass-spigot/p77983 It's purely for a temporary application where I have this particular toolstation spigot available and also have a 15mm JG push fit end cap stop. And...

    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?

    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...

    Will this do the same thing that the following will do? because it mentions for outdoor taps.

    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?
