I have a couple of taps by the old chicken coop, but wanted to add some by the new one too. 

So first up, I dug a ditch for the new pipe, intercepting an existing pipe:

Then I laid out the parts:

And assembled them:

Looking closer, there’s a valve to shut off the pipe after this point (water flows from right to left), since that isn’t used, plus a capped expansion point for possible future use:

And a two-headed tap, so so I can have both a hose to refill the chicken water, plus a timer and irrigation for the window boxes:

And another expansion point inside the chicken run, for a possible tap there:

I also wanted to replace an existing junction next to the old coop, that had a valve with a broken handle:

The new multi-valve system, that lets me shut off water to different areas of the garden, and includes an underground tap that I could use in winter, when the rest of the taps are off:

Here’s the overhead view, showing the valve box:
