Thanks for the suggestion. i think i'll stick with the magnet idea for a
while, because doing it that way gives a bit of extra pull to hold the
valve closed beyond the end of the normal travel - if i use a latch
there's going to be some slack taken up when the water drains again, and
the valve may end up leaking slightly.

The other way i thought of was to just use a permanent magnet, and have a
solenoid pushing the ball*** away from it to start the watering cycle.
