Oh dear - as they say - a little knowledge is a dangerous thing! Pure water is an insulator, although quite how pure is the water in your pipes is another matter!

I suppose the water itself is grounded, so contacting a metal faucet would ground whether the pipes are metal or PVC. No virus found in this outgoing message. Checked by AVG Free Edition.
