Drip irrigation from water butt

Has anyone successfully set up drip irrigation from a water butt?

I'm still on wanting to recycle grey water this summer and was thinking of draining it into a butt. I know it can't be stored, but to be used the same day. Last year I had hose pipes to syphon from bathroom and while it worked and meant everything could have a good water even during the ban I'm looking for something simpler this year. I can drain from the bathroom onto a canopy beneath, which is connected to the house fall pipe as one option.

We have the advantage that the patio, and fall pipes on the house, are higher than the garden. All the garden slopes away downhill from the patio. Previous years I've failed at watering enough but id like to make a better go of the garden this year and get some better growth on the plants and less mildew from my poor watering. We have a clay soil, wet in the winter, baked dry in the summer. 

Anyway this is the type of kit been looking at, and I guess there would be some way to connect it to a water butt (?) and would maybe (?) have enough pressure for it to run? Think the pipes tend to be about 4mm diameter. 



Also can someone explain the kit that comes with a water butt for connecting to fall pipe. Is this always a diverter? (if that's what it's called) What happens when the butt is full as it'd need to go back down the fall pipe instead of overflowing from the butt. I've not had one before. 

What's people's thoughts please?  Think it could work?

    Admittedly as a measure to prevent flooding once the butt is full and overflows, I bought a simple fixture that I inserted in a hole about six inches below the 'full' level of the butt.  After drilling the hole, I fixed the piece and sealed it with washers either side.  This left a 'spout?' on the outside, to which I attached a long cheap hose from a German supermarket so that, if there's room in the butt, rainwater is saved but, once full, it runs away down the hose to wherever I place the other end of it.  The normal tap at the bottom of the butt enables water to be taken when the butt is only part full of course.

    I've used a water butt with a valve timer to drip irrigate my tomatoes etc while on holiday. But that was only a very short run over 5 pots. 
    The connection from water butt to drain pipe is straight forward, when the butt fills above the intake level it diverts back into the drain pipe. 
    It worked fine in the greenhouse, not sure if there's enough head to water over a larger area.

    As a child we had the waste water from the bath and sink down into a huge water butt...and I mean huge. It wasn't used in a day but kept for when it was needed in the garden.
    So @InBloom I am not sure why you have to use the grey water in one day.
  • @InBloom in order to use a water butt for drip irrigation you need a water butt pump as there wouldn’t be sufficient enough pressure using the water butt alone.

    I've done this on my greenhouse butt. Its too far from the rainwater drainage to plumb in properly so all overflow goes to the very dry bed under my big oak tree.
