I need to turn off the water supply to this washing machine.

What kind of a valve is this? How do I operate it?

Furthermore, why are there three rubber wires that leave the hot and cold water pipes?



Maybe these two steel nobs are opening/closing the valves? You see them? It's those two steel colored thingies, one on the right, one on the left.

Furthermore, what are those cylinders for? What the hell is that? I've never seen that before.

    Hot and cold to the washer, maybe a line from the cold for steam to the dryer? It’s hard to tell from your photos, but I suspect the valve is above where those hoses come out, maybe quarter turn valves?

    I don’t see a shutoff. Perhaps more pictures like the first. Three water lines are likely cold, hot, and one for a steam feature on your dryer Commented Jul 12, 2019 at 2:49

    There are no valves there. All those "knobs" are hose connectors. Commented Jul 12, 2019 at 13:30

    The original photos were photos of the screen of a special camera. Very weak in red, so super cyan. Fixed in photoshop. Commented Jul 12, 2019 at 15:03

Those two knobs, the tiny ones on the inner sides of the hose connectors are the valves.

  • I’d love to see a picture of it removed cause I still don’t recognize a valve even with the arrows Commented Jul 12, 2019 at 23:23

The cylinders are to reduce water hammer (they are basically shock adsorbers for the water that's moving in the pipe being suddenly stopped by the very fast valves inside the washing machine.)
