Counterpoise sounds like a good way to go. Wire mesh is much better than 
solid as it reduces eddy surrents.A large number of thin bare wires laid out 
radially, (like a daisy) would be better yet.

      Did I miss something here? If you block the RF going to ground then 
you again have no RF ground.

If your plumbing supply lines are indeed plastic, then your faucet is not a 
ground. IMO it is an electrocution device if you wire to it !!
