float valve

    Does anyone recognise this type of ball valve please?

    This ball valve has started leaking and, if possible, I'd like to repair it by either replacing the rubber diaphragm, or the whole unit but without replacing the inlet connection (which has a captive screw which connects to the valve). However, although I've searched through many online...

    The curious case of the 20mm pipework

    Ladies and Gents, My house, it seems, is slightly non-standard. I need to replace the float valve in my cold water storage tank, but of course it doesn't seem to have a standard 15mm fitting. I believe it to be 20mm, like the mains water stopcock fitting, which is "actually" a thread diameter...
