OzBargain Plumbing Advice Needed (Connecting Washing Machine to Drain Pipe)

Moved into my new house and cannot connect the Washing machine to the drain pipe.

I’ve made a few Bunnings trips and cannot make it fit on.
I’m a tight ass to call a plumber for that.

Edit ** more photos and yes washing machine that can’t have the drain over the sink as its under a bench top.

  • What does the line from the dishwasher look like? Seems like a simple fit…?

  • OP is asking about a washing machine????

  • Washing machine or dishwasher? Looks like for a dishwasher outlet pipe found under a kitchen sink…🤔

    Unless you have placed a front loader into where a dishwasher once was??? I know some people have washing machine in the kitchen, but in an apartment at another country.

    • It’s in the laundry the washing machine

  • I think you mean dishwasher, and that grey hose at the back just gets forced on.
    The rubbery end gets stiff after a few years, but you just grind it on.

    • It’s in the laundry for the dish washer

    Boil the kettle and put some of the hot water in a mug. Dip the end of the pipe on the water for a minute or so, this softens the hose, then stick it on.

      OP needs to show photo of the washing machine outlet pipe, if it is one of those that hang on the side of the laundry sink, won’t be compatible…

      • That's very true, I made a bit of an assumption there.

      • Photos added

  • Is it just me or the outlet looks bigger than normal?

      Maybe it was just happy to see OP

  • What is the problem? Can’t fit it on the spigot or hose won’t reach around properly?

    Soften the rubber ending by placing in very hot water for a few minutes (from a kettle, not hot water tap).

    If you still can't force it on you may have a size mismatch. In that case just purchase a new drain hose with a larger diameter ending.

    • I was about to say that about softening the rubber.

    • This, but with some added info.
      Principally in plumbing, the direction where the water flows needs to go INTO the pipe under it, otherwise you'll always have leaks. The drain inlet looks significantly smaller than the washing machine hose so I think you'll have a fight in your hand trying to fit it in, but there's no harm in giving it a try.

      You have a screenshot of the outer diameter of the inlet pipe, but what you need is the inner diameter of the inlet. The WM hose needs to go INTO that inlet. Ideally once you know the OUTER diameter of the washing machine hose and the INNER diameter of the inlet, go to a hardware/plumbing shop (eg. Bunnings/Reece) and get a pipe reducer that fits both measurements (possibly something like this, but whatever works to make the WM hose smaller to fit into the inlet). This set up prevents leaks, but to be totally sure there are no leaks, (presuming the reducer is PVC), you can use pipe sealant (please read the PSI before use) but be aware if you ever need to take that pipe off in the future you may have to saw the WM hose off.

      If all else fails, have a look if any of these diameters fits what you're looking for, they're designed to couple to pipes externally. Make sure you read up/watch youtube videos on how to tighten these before you do it. They're not what you usually go for when joining PVC but will work if you're out of options.

      • Not in this case, the hose goes over the spigot and the barb helps prevent the hose from coming off in conjunction with a hose clamp.

        • True, but then you need to make sure that you've attached the right-sized hose so it's airtight. For a newbie hack job it's easier to prevent leaks going by the first principle of upper pipe going into the lower pipe. Leakage usually only happens when there's blockage.

          Basically OP, the correct way to do it is to flare (by putting it in hot water ~5 minutes) the WH hose rubber end and wrap the inlet with it then seal the end with a hose clamp. This needs to be airtight or you'll have water leaking constantly and I can see a power outlet near that location. My suggestion to insert the WH hose is the general leakproof approach for newbies as it's harder to fail and causes a leak unless there's a blockage downstream but you do have to find the reducer.

    Don’t forget that the spigot maybe blocked if it is all new and will have to be drilled out if you haven’t already done so.
