    DIY isolation of unvented cylinder

    Thanks - yes from memory I'm sure it was a gate valve - I'll just use the stopcock then. It's a fairly new cylinder and I think he does keep it up to date with servicing so no worries there To clarify - charging the airgap when the system is already depressurised (not drained down) should...

    DIY isolation of unvented cylinder

    Hi all I've agreed to do a simple job for a friend on their plumbing system - they have a weeping joint on the domestic hot water, so a simple isolation of the system and replace the joint. They have a boiler downstairs feeding an unvented cylinder in the loft. I didn't see an expansion vessel...

    Supplementary Bonding Bathroom

    Hi all, I know this is one of those questions where there's no black or white answer, but as a DIYer I wondered if there was any basic advice you could give me regarding bonding in a bathroom... I'm about to undertake a total bathroom renovation - back to brick and all fixtures and fittings...

    Wiring 2 gang switch with one 3-core cable

    Presumably it's no different to using a T&E for a single switch (live/switched live - no neutral)? Neutral will be looped at the rose (or more likely an MF JB under the floorboards of room above) I'm imagining this conduit will be a bit sharp and rusty (as others in the house have been) so I...

    Wiring 2 gang switch with one 3-core cable

    Hi all I have a single 1 way light switch fed from the ceiling via chased metal conduit (presumably original to the house 1950s). I want to add a second 1 way switch (for a new light) to make the switch 2 gang. The conduit is on the narrow side and I wonder if I'll have difficulty feeding two...

    Alteration of existing window opening

    Sure - I meant that due to FENSA, I'd be getting the whole job done professionally rather than having a go myself. My initial thought was that you wouldn't need approval. But I ask because I found the following on my local council's website: Q: Do I need to make a building regulation...

    Alteration of existing window opening

    Hi all, Upcoming kitchen re-fit will require moving some windows around - one window in the kitchen needs bricking up and another one needs slightly altering. It's a small alteration - the current window is 1500mm wide x 1000mm tall. I'd like it reduced to 1100mm width - and I'm happy for the...

    Garage Door frame fixing

    Would something like gorilla glue be preferable to silicone then?

    Garage Door frame fixing

    Thanks for the replies. Yes they are side hung, and yes the instructions state to use brackets rather then fix directly through the frame. If you think the silicone will struggle to hold the upvc trim to the frame/timber, is there anything better? Gripfill etc? I assumed silicone was best as...

    Garage Door frame fixing

    I'm replacing my timber garage door and frame with a new steel door/frame. I've ordered a new door in a standard size and there will be an approx 25mm gap between the steel frame and the brick opening on either side of the door (the frame should fit well vertically). This is a bit too wide to...

    Quick plinth heater question

    Just a quick question... I want to fit a hydronic plinth heater where the fan comes on automatically whenever the heating is on. With plinth heaters, does the fan come on automatically when the unit detects warm water flowing through, or would I have to fit an external flow switch on the...

    Surface clipped cables under kichen worktop

    Quick question for a Sunday evening: I'm planning new kitchen layout and thinking about socket positions etc. I read on here about how it's fine (though opinions vary!) to have chased cables above the worktop and then switch to surface clipping for below worktop in the service void behind...

    Window fitter or builder?

    Hi, I have two windows in my kitchen that I want changing to make room for a new kitchen layout. Both windows are about 1500x1200. I want one window changed to 900mm wide and the brickwork around the new smaller window made good. I want the other window removed and bricked up completely. I...

    Combi Boiler - bypass radiator necessary?

    It's an Ultimate 30c. Unless I've misunderstood the manual and diagram, there is an internal non-adjustable automatic bypass fitted. Clearly not sufficient though. Yes - the bathroom is within earshot of the boiler, and when all other rads are already closed, you can hear the boiler groaning...

    Combi Boiler - bypass radiator necessary?

    Thanks for the replies all. I had RTFM - the boiler manual states that there is an internal non-adjustable bypass. The boiler isn't cutting out, just sounding unhappy, so maybe it just needs a more sensitive bypass. I'll fit an external ABV and see if that cures it - for now the bathroom rad...

    Combi Boiler - bypass radiator necessary?

    Hi all, I've recently installed a smart heating system (Evohome) which uses TRVs to control each radiator independently. I've put an Evohome TRV on all the radiators, including the bathroom radiator which was previously fitted without a TRV to act as a bypass radiator. The idea is that Evohome...

    Bricking up a window - building regs

    Thanks for the reply - is it as simple as that? Seems to be the opposite of the advice given here: //www.diynot.com/diy/threads/bricking-up-a-door.213202/

    Bricking up a window - building regs

    Hi all, I'm planning a kitchen renovation and as part of that I'd like to brick up an existing window to free up more space for wall cupboards. There are other windows in the kitchen so there's no problem from a lighting point of view. The walls are solid brick 9". My question is: in bricking...

    Table lamp earthing

    Well that was my thinking. The neck of the bottle is a good deal wider than the 20mm conduit, which I will fit in place with gripfill or something similar (will be hidden by the lampshade so not too concerned by looks) - there's likely to be at least 5mm of clear air (or gripfill!) between the...
