Right, of course...how are you going to isolate the sink so it
isn't grounded when it's _full of water_!

What happens when all your drain pipes are made of abs plastic? What do
you think the resistance to ground is of a tub of water? And we're not
exactly talking about salt water here.

No one ever touches a sink unless they want to turn the water on
or off? How does one reach in to get a utensil off of the sink
bottom without triggering the water control?

If extending the touch-control surface to the sink itself doesn't work
as intended, then don't do it. This particular Delta faucet doesn't
work that way anyways. Only touching the spout or the control lever
will turn it on or off.

You have an idea, unfortunately it's faulty. I'm not arguing
with you, as there's no point. You can easily prove me wrong
by rigging your capacitor total sink control and patenting it.
I just hope you have deep pockets and aren't thin-skinned.

I have no interest to commercialize any idea. That was never the point
of this thread. I don't know why you're being such an asshole about it.
