    Rcd tripping but cannot find fault

    Had a bit of a flood due to last night's heavy rain, and woke up to find the rcd thst protects my downstairs ring main had tripped. Verified that it was that circuit causing the problem by switching it off at the mcb and leaving the others active at which point the rcd stopped tripping. I...

    Got a new combi boiler, suddenly noisy central heating

    So I had a new boiler installed (an Ideal Logic 24) and while my heating is now running much more reliably, and the boiler itself is much quieter, I hear water noise in every room, whereas before the system was almost silent. I suspect that the pump in the new boiler is circulating the water...

    brick cleaner

    Might also be a good idea to brush gently with a wire brush first, to get rid of any larger chunks of mortar that may be loose.

    Can't drill through wall

    Had a similar problem in my house. For some reason known only to the original builders they decided to build all the internal walls out of engineering bricks. And the outer face of the external wall. Been causing me no end of problems.

    Tying thermalite blocks to 73mm bricks...?

    Been looking for recommendations on this problem for the last hour or so, and am getting thoroughly confused. I'm building an extension with 73mm bricks (so that they match the existing 1930s-built house) and thermalites on the inner leaf, which means of course that I'm not getting good...

    Sudden leak in mdpe/push fit central heating system?

    Concrete slab floor - getting it level in a single pour

    (Apologies for reposting this; I think I originally posted it in the wrong place, and don't seem to be able to move the post.) I'm planning on pouring a concrete slab floor in my extension, and have been advised that it's possible to pour it in a single 100mm smooth concrete slab rather than...

    Covering drains?

    Hmmm... adding to the confusion, polypipe's technical guidance (http://www.polypipe.co.uk/cms/toolbox/Technical_Installation_Guide_Above_Below_Ground_Drainage.pdf, page 34) doesn't specify the 300mm bearing -- it just shows a concrete slab directly on top of gravel. Will BC accept that I'm...

    Covering drains?

    Looking for a suggestion of what is an acceptable way of covering drains. I'm building an extension and need to run a new rainwater drain from the front of the house to join with the existing combined drainage system at the rear. I was planning on running the pipe immediately adjacent to the...
