I am building a laundry to landscape greywater system. I have seen some people in some videos that are using T fittings as 50% splitter like in this image:

(taken from here)

You can see that the water that flows from the source pipe is being split to two destinations:

  1. The basin that is watering each tree.
  2. The continuation to the next tree.

My question is, is T fitting actually considered a 50% splitter ? Because I would imagine water will want to continue flowing in a straight direction, so most water will continue flowing and not “turn” 90 degrees in the pipe for the tree basin.

Remember that water is not going in pressure, but with gravity.

So why do I see so many of these designs and are they correct ?

Thanks

    The round frame is the basin? I’m not sure I understand your setup, but that’s OK.

    The basic idea is, water flow occurs due to pressure difference. To force the water to multiple exits, you need pressure. The easiest way to achieve this is to use a large-diameter pipe as the main feed, then place small-diameter outlet pipes along it.

    If you have an open exit like in your picture, the pressure will be lost.

      Thanks for your answers The round box is the basin in this example. But that’s not exactly my setup. In my setup, instead of an open ended exit directly there, I would take it through a pipe to the basin where it would pour open ended… So not that different I guess.

      I get what you mean about the pressure. My only doubt is that since it’s greywater, it might have slight dirt / hair etc coming from the shower and washing machine that may clog small pipes. I know I can add a filter but I’m trying to keep it simple
