    Hey all,
    I’ve googled for ages but can’t seem to find what I’m looking for.

    I’m having to replace my dishwasher - the old outlet hose screwed into the trap/pipe for the one and a half sink (see picture below and yes that is a latex glove acting as a blank).

    the new dishwasher outlet needs to be pushed onto a nozzle and (I assume) secured with a jubilee clip.

    Not sure if I can just get something to screw into the old outlet fitting that converts it to a nozzle - or do I need to replace the whole connection (circled).
    If so - what should I google / search for?

    cheers!
    Garry

    Are you looking for something to screw into the connection where the rubber glove is? If so that looks like a normal spigot end connector and would take a normal appliance spigot connection. Don't think you get them separately though, probably need a new trap waste.

    What was on the old Dishwasher, may be possible it could be reused?

    thanks - this might be the very chap. Existing thread seems to be 1inch.

    there is a city plumbing not far from me so def worth a go at £2 before I buy a whole new trap / waste.

    will let you know if it works out.

    Threaded connections in plumbing are very often in BSP sizes.

    What the size is called is not the same as what is measures.

    For example a 3/4 Inch BSP fitting measures 26.44 mm / 1.041"

    And has 14 threads per inch.

    A one Inch BSP measures 33.25 mm / 1.309"

    And has 11 threads per inch


    Others are in metric sizes.

    For example 25mm which is almost one inch.


    Can you measure it very accurately please across the diameter of the thread.

    unfortunately they uplifted the old one when delivering the new one and before I realised the outlet connections were different.

    Ah. Hopefully not too difficult or expensive to remedy though. Random Grinch may have found exactly what you need, wastes are usually pretty standard across the manufacturers.

    It’s really tricky to get into, but measuring with a metal rule it looks like it’s 25mm across the diameter of the thread.

    Every day's a school day, I didn't think they did those spigot connectors separately.
