  • Hole Size for Plumb-In

    Hi
    Im provisioning for a plumbed in machine for home in the next few months, and Ive been told a 50mm hole in the bench will suffice.

    I forgot to ask this at the time, but as Id like to get a drain line too, is 50mm wide enough for both water feed and a waste / drain line or do I need to go wider ?

    i reckon it would be enough as the water line is about 10mm and the drain is about the same depending on what you use.

    are you putting the electrical wires down that hole as well?

    you need a wide enough hole to pass the "nut" of the water line and the plug of the "wires" unless you remove the plug.

    mine runs down behind the stove and it is only a gap about 25mm but is a rectangle so they are "stacked" i had to remove the power wire and re attach (by sparky) to get it to fit

      Grab your self one of these for the bench top they come in a few sizes and different colours. Bunnings do stock them as do most hardware shops.

        Thanks Maheel.
        My original thinking was to run both grinder and machine off the powerpoint above the bench on the splashback. Your point is worth considering...definitely neater

          @Beanflying - do you knock out the middle, or do both lines fit through that little window ?

            my rotary pump is external so the wires go underbench and i put a plug on the pump for easy removal

            but the main power goes above the unit. I prefer it there so i can kill the power after i turn it off. but was something to consider in your design.

            i would include something like the plug that BF posted if i needed to cut a hole, neat and tidy it has a little bit you sort of twist to fill the gap, you insert the middle after you run the wiring through the outer bit

              The way the grommets work is the centre comes right out so you can pass plugs through. You then put it back in and you can shut down the opening to as small as you need with the sliding shutter. Under $10 BTW
