    WB Highflow 400 diverter valve

    My WB boiler (above) keeps tripping out the thermal cut out, seems to be lacking the hot water pressure it used to and is now intermittently losing the hot water momentarily. Most of this is when the heating is on. Having looked through this and other forums, it seems the diverter valve may be...

    Shower Identification Help

    Here's one to test your knowledge! I have a leaking thermostatic shower which, if I knew what make it was, I could look at getting a new cartridge for. However, there are no markings on it at all indicating the make, let alone the model. Does anyone recognise what it might be from these...

    Phone wiring confusion

    I have just found an additional phone socket in our new house, which upon testing was found not to work! I have looked briefly at the wiring, and can't make out what has been done - hence posting this question! I shall try to explain what I have found. There appears to be a main incoming...

    Additional/moving aerial socket

    I am wanting to either move, or preferably add, a TV aerial socket in my lounge. The aerial is roof mounted, and the lead runs down the roof, down the outside of the house and enters the lounge through the window frame and into the aerial socket. The aerial only serves this socket. The ideal...

    Non - dichroic lamps

    Not reallyy a household electrical issue this one, but one that someone might be able to help with. I have a set of push-bike lights which normally have a 10w 12v MR16 in them which I have replaced with a 20w MR16 (hang the runtime!) however, the body of the lamp gets pretty hot, especially...

    Testing RCDs

    Gradually reducing flow on Hot Water

    Hi Folks. I have a bit of a wierd one on my Combi that I can't work out what is happening. When I run the hot water tap at anything less than say 1/4 or 1/3 pressure, the water comes out fine, but then slowly diminishes into a trickle and hence the boiler stops firing. Opening the tap a bit...

    Moving non-condensing combi boiler

    I want to move a non-condensing combi boiler to another location in my kitchen (only 2m away). I have contacted one plumber who indicated that they may not be able to do this as it would be treated as a new installation and hence would need to be a condensing boiler. Surely this can't be the...

    Combi Boiler Draining

    I want to drain my Combi Boiler system, but it says in the instructions not to use the pressure relief valve screw. However, this seems to be the only drain in the whole system. Any ideas why it says I can't drain it through here? The Combi is a Vaillant VUW232 Thanks Jim

    MCB Wiring holes not lining up

    Hi - I have just purchased components to wire in a consumer unit in place of my old fuse box (ie CU box, 100A incomer switch, 80A RCD and 4xMCBs). However on 'dry' assembly, it seems that the wiring/busbar connection holes on the MCBs do not line up with the with the incomer or the RCD. The...
