    Making S-unions watertight for a Hansgrohe shower

    yeah, it seems so. But that of course does away with the whole point of the s-union. Is there such a thing as a straight union that reduces from 3/4" at the mixer end to 1/2" at the backplate end? It would need to have a flat bit in the middle to get a spanner around. The s-unions are doing...

    Making S-unions watertight for a Hansgrohe shower

    heh. ok, ok point taken. Seriously, this is the first time that I've had to use PTFE on it's own (ie, not as a backup seal to a compression fitting or washer). Thing about the s-unions is that for them to do their job of allowing positioning of the mixer, they can't both be screwed in until...

    Making S-unions watertight for a Hansgrohe shower

    Hi all, My Hansgrohe mixer shower was supplied with a couple of s-union fixings to connect the mixer to the backplate elbows that I have installed: back plate elbows s-union I can see the point of the s-unions in that they allow for discrepancies in the pipework positioning, but...

    Extractor fan

    The shaver socket currently installed is permanently live, with no means to isolate it. I don't want to do this using the light switch, as it's useful (for razor charging / electric toothbrush) to keep it live when the light is off. However, i do think it needs to be running through an isolator...

    Extractor fan

    I'm about to put a timed fan into my bathroom and i've seen a few triple pole isolators on the web. Can you get fused versions of these? If you can't then presumably you'd need to provide fuses elsewhere in the circuit, if you wanted to go with one. If i'm using the light switch to control...

    Problems with system after replacing radiator

    WORKING AGAIN! Thanks for the advice folks (quickest forum i've ever used!). I bled the pump, which i hadn't done before, for ages and suddenly the boiler kicked back in. Everything seems to be ok now. Didn't realise that air was such an issue - i'll know better next time. cheers Pete

    Problems with system after replacing radiator

    Flicking that switch seems to have no effect. As it's motorised i would expect to hear the motor briefly when i flick the switch - but nothing happens. I read somewhere else on the forum about a guy who got his system clogged up with gunk when he refilled it (header tank contained years of...

    Problems with system after replacing radiator

    no, i didn't touch the valve when i filled. By opening it, do you mean flicking the switch from auto > manual as you described above? Pete

    Problems with system after replacing radiator

    Thanks for the quick replies The system seemed to fill fine, in that all the rads are full (including the new one i installed). I thought that any air in the system would move around until it found the top of a rad to get trapped in, and could then be bled off. Is it possible that air is...

    Problems with system after replacing radiator

    Hi all, Please excuse me - very new to all this. Today i drained the system to put in a new heated towel rail. Beforehand everything was working fine. I turned the water back on, bled all the rads ok, but the boiler now turns itself off after about 30sec and i guess must be tripping the...
