    Continuous water noise greenstar but no leak

    I have a Greenstar 25si Worcester. Both the hot water and heating work ok. The problem (just occurred) is I have a continuous running water noise most apparent from the hot water (taps) outlet pipe under the boiler. I eventually traced it to that using long screwdriver to ear. When I shut the...

    Hi as title with DT20rf control panel and a wireless thermostat in the hall. We had a power cut and now even though the thermostat is calling for heat, the boiler is not doing anything.

    I switched the MCB off to change the cooker socket to a new one after decorating. I checked power was off with fluke tester shown in pic. During the process the RCCB tripped.

    Recommended way to add power cord to socket where plug won't fit

    I want to plug in a power cord. But the plug socket is behind a unit so there is no space for the plug. It is a 2-gang socket so I can't use a flex outlet plate. Am I allowed to remove the plug socket and connect the wires inside a maintenance free junction box such as the Ashley J803 leaving it...

    What washing machine spigot to attach to 32mm solvent waste?

    I have created a new waste out of 32mm solvent weld. I have used all Hunterplastics items for this, which are nominally 32mm (actual 36mm). (I know it is possible to join compression pipe to solvent pipe by using a straight compression fitting). So, I have a solvent weld upstand pipe for my...

    what constitutes a new circuit?

    In my own home am I allowed to add an extra socket on the ring main? (no actual increase in number of sockets since I will be removing an unwanted one. So in a sense re-siteing a socket I suppose). Am I allowed to rewire parts of a ring circuit to remove inaccesable junction boxes fitted by...

    How close to these downlights can I put insulation?

    Haven't got a decent pic but the flat downstairs has had new downlights fitted recently you can see two of them in this pic. I assume they are fire rated. I intend to put Rockwall Sound insulation between the joists. Although rockwall is non-flammable I assume I need to leave some clearance...

    Am I allowed to change flow switch on potterton 80?

    legally? I have established I have the problem of the dhw flow switch sticking on (causing overheating and lockout) so it needs changing. Am I legally allowed to change this? I am not a heating engineer or gas safe. Not sure what the legal position is these days, years ago I would have just...

    Am I allowed to replace this junction box?

    I'm changing my kitchen and noticed this junction box screwed to a joist under the floorboards. I know they are meant to be accessible and this isn't. I am just asking if I am strictly allowed due to laws etc. as I don't know so thought I'd ask. I would replace with WAGOBOX and connectors.

    Leaking down from extended party wall / chimney - pics

    Hi WE've got a leak! I assume this area was once 'fillets' that have in the past been concreted over (probably due to leaks) and I would imagine this is where our leak is now coming from? - When it rains, rainwater almost immediately starts to run down the chimney breast in that attic room...
