    Got one of those flexible shower hose type toilet hoses. Instead of a gun attachment it just had a small nozzle but that has now been accidentally flushed down the toilet (don't ask, no idea).

    Looked everywhere online but can't find a replacement nozzle, either separately or as part of a set. All it was was a tiny, slightly conical-shaped nozzle that screwed on over a 15mm plastic thread.

    Anyone able to link me to one?

    Cheers

    They break the Water Regulations (unless very carefully and expensively installed) and should not be used in the UK.

    The nozzles break water regulations? Or the whole hose?

    We had it professionally installed. The hose works fine - just needs a nozzle.

    1. The whole hose including the nozzle.
    2. They require an air gap to prevent back flow of category 5 fluid - which covers anything to do with WCs.
    3. The only realistic way of achieving this in the UK by making supplies to the hose come from a separate tank with an air gap between the inlet and the contents of the tank. Applies to both hot and cold.
    4. Non-return valves are not rate for category 5 fluids.
    5. So, to have a cold only one you need a tank installed, with its own overflow, and pipework from tank to point of outlet.
    6. To have hot and cold is twice the work.
    7. I'm afraid that:
    7a. The fact that people sell them doesn't make it legal to install.
    7b. Paying someone to install it doesn't make it a professional installation.
    8. If you wish to find out more have a look at the Water Regulations Guide.

    OK, didn't know any of that, thanks for the heads up...

    Can you clarify for me - how is the backflow actually caused? Is it only when water enters via the nozzle and flows back up the pipe? So e.g. if you submerge the end of the pipe in the toilet water (not sure why you'd do that) then some water might flow in and run back down the inside of the hose when you hang it up? Or does having a hose fitted make it possible that water from the toilet will enter the drinking system when you simply flush?

    Unfortunately you have hit a nerve with us other professionals on here.

    An ablution spray or douche should not be installed onto the hot/cold mains water supply next to a toilet in the UK. It breaks the water regulations and as such are illegal unless they have Category 5 backflow protection as part of the install. The fact that the end has gone down the toilet is exactly why they shouldn't be installed.

    Typically the installation would set you back over £500 if it was fitted correctly and probably wouldn't work very well unless installed at least 5m above the outlet. If it didn't cost that then it shouldn't have been installed and unfortunately your professional shouldn't be calling himself a professional.

    If the outlet was accidentally dropped into the toilet then faecal bacteria can easily travel up through the outlet, multiply and from there gets into your mains water, which is used as drinking water etc.
