Who all does this? Havnt done any research if it is required anywhere or not, but just wondering out of practice how many of you all do it?1515AC40-8AF0-4A26-B455-386BC0A94E70.png
 
In Washington, it is accepted that mixing valves complete the hot to cold bond. If its an older home with separate hot and cold water faucets, it may be necessary. I used to install a 4 WAG at the water heater from hot to cold.
 
Technically its a good idea, nothing worse than having remote or floating earth at half the handles people will grab when wet.
 
I haven't done it for a while.
It's for when the whole house is piped in copper, even the main. Nowadays I think every house I see has all pex
 
In Phoenix, before I moved, it was required in Pex homes at the water main if the line running from the meter to the shutoff was copper. Made no sense to me since there was no metal interior piping. In some surrounding areas, you had to catch the hot and the cold at the water heater which is usually where we took the water bond. The reasoning being that, if you removed the water heater, there was no continuity.

Some where in the code it states that anything that could become enegized must be bonded. At a IAEI class inspector brouht up a great point. If the stainless steel sink is feed by pex should the sink be bonded? Have to remember that not all houses have garbage disposals.

Even if the house were plumbed with copper or steel, continuous to a metallic underground city main, the kitchen faucet wouldn't provide a reliable bond. It's often fed with non-metallic risers, is mounted between non-metallic gaskets, and/or has a non-metallic body.

How would a metal sink be likely to become energized?
