    Drawbacks of sealed system?

    That's the tricky bit. Due to the fact the boiler is in the garage and the existing CF and OV connections are in the airing cupboard, it is going to require a long and fiddly run of copper to get from one to the other. Not spoken to him yet - only listened to a voicemail. Got the impression...

    Drawbacks of sealed system?

    Hi, Our heating system has a number of little problems, including: - some rads get a bit warm when hot water (only) is selected on the controls - a couple of rads do not get as warm as the others when CH is on - air can be heard in the system (bubbling noise if you listen to...

    Cleaning system

    Hi, The house we bought a few months ago has a boiler which was installed in around 2000/2001 and radiators which (I guess) date from when the house was built in the early 60s. It is a standard open vent system. My first concern is that the system may not currently have enough inhibitor in...

    Test Supplementary bonding

    Hi, Is there a simple amateur (i.e. me plus a multimeter) way to test of a bathroom has any supplementary bonding? There's nothing visible, but the bathroom was only refitted about 2 years ago so maybe there is some bonding going on under the floor..... :?: I have got a positive...

    120V earth??

    I guess before I do that I need to get the light fitting down and see what the wiring looks like in the ceiling too. It may be that the CPC is actually meant to be there after all and is just connected to the wrong thing in the ceiling.....

    120V earth??

    I'd actually be surprised if the CPC is connected anywhere. The house is from the early part of the 1960s and so the original lighting circuits are all wired with PVC covered T-without-E cable. My suspicion is that at some point, someone has replaced the cable from the WC light ceiling...

    Running cable to a shed

    Others will be able to offer better and more in-depth advice than I can. However, I suspect the answer will be that to do this properly you will need to run an armoured cable underground from the consumer unit in the house to the shed and then feed that into an RCD protected consumer unit in...

    120V earth??

    Hi, I have now finished converting all my unearthed metal light switches to plastic as talked about at http://www.diynot.com/forums/viewtopic.php?p=827868 Interestingly, it turned out that for two of the rooms (the bathroom and downstairs WC) we actually did have a T&E cable serving the...

    Thanks for the responses. Most reassuring. Did anyone have anything to say on this bit:

    changing socket in shed to RCD socket

    Related to this, I know that if I want to put up a new outside security light, it is non notifiable if it is on the outside wall of the house and there is no exposed external cabling (point l on page 9 of http://www.planningportal.gov.uk/uploads/br/BR_PDF_ADP_2006.pdf). For the purposes of...

    Part P for thermostat

    Pretty much what I thought. Whilst I support the spirit of Part P on the whole, I do think this is one of those instances where paying LABC £120 to inspect the install of a £90 thermostat is a bit OTT. Maybe I will save it up and "officially" install the new stat as and when I have to get...

    No, but it could easily be arranged if i replaced the SFCU with a 13amp socket. :lol:

    changing socket in shed to RCD socket

    According to Table 1 on page 8 at http://www.planningportal.gov.uk/uploads/br/BR_PDF_ADP_2006.pdf (plus note f), a shed is not a special location. It also suggests that replacement of an existing socket is non-notifiable, regardless of whether it is in a special location or not. I am in no...

    Part P for thermostat

    Hi, Our central heating system previously had no room stat. It just relied on TRVs. So, last weekend, I installed a wireless Honeywell room stat/programmer. This involved running two lengths of twin core cable from the central heating junction box to the wireless receiver unit - one...

    Metal light switches

    Yes, there is continuity between the screw holes and on the back. And yes there is an earth terminal. But if there is no continuity across the face edge, then where is the danger of a shock?

    Metal light switches

    I haven't replaced any of the KO boxes with dry-lining ones myself. The plastic boxes that we do have are some kind of old-fashioned looking plastic things - not the modern day things designed for plasterboard walls. With that in mind, does your advice about metal screws being okj still hold...
