i sure it does not comply to the manufactures instructions.

250.96 Bonding Other Enclosures.
(A) General. Metal raceways, cable trays, cable armor, cable
sheath, enclosures, frames, fittings, and other metal non–
current-carrying parts that are to serve as grounding conductors,
with or without the use of supplementary equipment
grounding conductors, shall be effectively bonded where necessary
to ensure electrical continuity and the capacity to conduct
safely any fault current likely to be imposed on them.
Any nonconductive paint, enamel, or similar coating shall be
removed at threads, contact points, and contact surfaces or be
connected by means of fittings
If you test the resistance between the ground wire and the pipe with your meter, I doubt that you will find any measurable level of resistance. Obviously I cannot test this connection, so that is my opinion based on what I can see in this picture. When I have tested similar installations, that was the result.
As for the manufacturer's instructions, manufacturers instructions and 110.3B are great - except that the whole concept of listing is to give the inspector some level of comfort that something complex that they don't have time to dissect will work for the application.
A grounding clamp is three screws and two pieces of brass, and the working of the clamp seems self-explanatory to me. As long as it will withstand the environment and provide a tight, low-resistance connection - mission accomplished.

Looks more like micky mouse than Goofy....
In all honesty, the inside radius of the clamp would not be a perfect contact with the pipe anyway however, the paint has not been sufficiently removed. After that is fixed I would expect the clamp to be installed correctly.
I have never required one.... not even once. I had one and it got my pants wet every time I shut of the valve. And yes I know what an awful admission this is. That's why I told you guys.

Not even for a faucet that is used to fill a spa or pool?
Well surprise, surprise, you do have a point there ... but no, never. These days there is a bib with a built in atmospheric vacuum breaker built in. AVB, I wanted you to know that I know what I ignored for a few decades.
So that begs the question, at every new pool do you get the valves changed? And if you do i wonder how the contractors take that one... you do know that they have no employees so it's plumber time.
