    Bottom of joists drilled and taped up wagos

    I completely agree! I'll have to double check on the wagos on the box. Thanks for your advice, I wanted to check that I wasn't being over picky. We'll see what bossman says tomorrow

    Bottom of joists drilled and taped up wagos

    I can see the pics when not logged in, maybe a refresh of the page would show them? On their way out they said let us know when ready for second fix, and they're happy for us to board the ceiling. The pictures are all of the mains rings. I was also under the assumption that MF boxes had to be...

    Bottom of joists drilled and taped up wagos

    We've just had an electrician in today to install some new sockets and a new ring for the kitchen and I'm a bit disappointed with the work. After my brief look, I've seen that they've done some of the following and would love your thoughts: - Drilled through the bottom of multiple long spanning...

    What sand for blinding on a concrete slab?

    Kiln dried? I guess I may as well fork out the extra for it

    What sand for blinding on a concrete slab?

    Evening all, I'm installing insulation on my concrete slab ready for UFH and a 50mm liquid screed. I think I'll need to install a very thin sand blinding to flatten out the slab a bit, however I can't find anywhere what sand to use above concrete. I ask this because there is a DPM below the...

    Steel beam sizing

    Good point! We can lower the ceiling slightly to accommodate a few more cm.

    Steel beam sizing

    Brilliant! Thanks very much. Given we want flush ceilings 203 is the maximum height we can afford. I'll update next week how the chat goes, and update with pictures hopefully next month when it's installed!

    Steel beam sizing

    Thanks for checking that! I'll give him a call on Monday and talk through all the points raised here. With the additional chimney load on the gallows I imagine the deflection would be even greater. If we needed a bigger beam, would it have to be taller, or would we be able to upgrade to a UC 60kg?

    Steel beam sizing

    Yes, that's what I was assuming that he was using average load figures and any small descrepancies were covered by the safety factors. But it's a bit job and I just wanted to make sure the house wasn't going to fall down! Thanks very much for talking me through the calculations, that's been...

    Steel beam sizing

    The walls are cavity walls, build in the 90's, so hopefully not too heavy. I've tried scouring the internet for recommended loads, however haven't managed to find anything. Thanks for that, it's good to know it should be fine. I've attached the rest of the calcs for the beam below. It looks...

    Steel beam sizing

    We're looking to remove a load bearing wall, which is supporting one wall of a gabel, the floor above, ceiling above and roof above. I've sent our structural engineers calcs to my dad and we're both a bit concerned. The above image shows the wall (and chimney to be removed). The wall is...

    Extend water main via loft for unvented cylinder

    That makes sense thanks. So really it's for an instance where your incoming is 6 bar, so that you don't have a pressure difference of 3 bar at the mixer tap which would cause the cold to take massive presidence. Theoretically if your incoming pressure is only 2 bar then the whole system could...

    Extend water main via loft for unvented cylinder

    So even though there is a pressure reducing valve just after the stopcock, the balanced cold isn't until after the pressure reducing valve just before the cylinder?

    Extend water main via loft for unvented cylinder

    I won't be doing the cylinder myself. All of the plumbers I've had round so far have looked at me like I'm speaking a foreign language when I've talked about running a new feed to the cylinder, which has left me pretty worried. I'm struggling to find someone who fills me with confidence, it...

    Extend water main via loft for unvented cylinder

    Am I being a bit stupid about the second pipe run coming back down? Can I just fit the PRV next to the stop cock and tee off the loo/utility cold supply before it runs up to the unvented cylinder?

    Extend water main via loft for unvented cylinder

    I'm looking to upgrade my vented system to an unvented system, and as part of that I'm looking to upgrade the 15mm pipe from the stopcock to 22mm. We've got 25mm in to the house and the stopcock is in the downstairs loo, it's in the boxing in of the soil stack. The pipe run to the airing...
