    Found at the dump, it looked undamaged so I lifted it for a looksee. Plugged it in, switched it on and it ran. Excellent.

    Connected it to a water supply, turned on the tap and it leaked so I started playing hunt the hole.




    Leaking from this part:



    A hairline crack, probably not seeable in the photo:



    It's in the detergent part of the fitting so it got cut off:

    2 off 2mm holes, either side of a venturi.



    Tapped and plugged with a machine screw and some thereadseal. Stainless steel screws, I'm not a bodger.



    Pumpy end of the thing:



    Worked by a swashplate. You can't really see it's angled:




    Back together for a leak test:

    Connected to the mains, no leaks:



    Electric motor back on:



    Pressure tested with the motor running and triggered a few times to cycle the pressure up and down.

    No leaks, ready to put in the shed:



    Not bad for free. It's lost the detergent function but that's not something I use so meh. No hose with it, but I've spares that I lifted from the dump before. Total cost of repair, 2 screws, an O ring, a drip or two of threadseal and about an hour of my time.

    Free upgrade from the last PW I found in the dump, that just needed a capacitor. This one is on wheels and has lance etc storage.

    Yesterday I gave away a Bosch jetwasher that only worked for 2 months. I bought a Karcher instead.

    Yeah I replaced a capacitor on one of those too - not much money from Maplins.
    And the hoses go on them after a while - the bearing in the tip goes iffy.
