It reaches down through a narrow (3" across) hole and turned the manual valve.
A similar device might work for turning a three way valve that's in a crawlspace.
Something as simple as a 2" pvc pipe with notches in it might work.
Irrigation valves that are between 1/2" to 1" are actually quite reasonably priced.
There is a large bump up in price above that.
If you filter the grey water before distributing it through the valves you should be able to use these smaller valves.
A tote, filled with mulch and populated with redwrigglers would probably do the job.
Good ideas. I especially like the irrigation valves - I've worked with those. I don't believe there are any 3-way irrigation valves but a small 2 valve manifold would do the trick. One concern with irrigation valves + less than perfect water... is stuck valves. Occasionally with well water or water from pipes with corrosion, we sometimes experienced valves that would not close.
Worth a try...as you point out, the price is reasonable. Thanks!!
