Moving Bonding Wire on Water Line

I would like to install a Moen Flo on my water line. It's a leak detection system with an automatic valve. It goes right after the main shutoff. There is an electrical bonding wire there. Is it okay to shorten this and raise it closer to the ceiling? Will I be able to cut this with my linesman pliers?

Yes you can raise.
If Moen Flo does not have metal parts all the way, you need to put a jumper. You can install Moen flo higher than current location of ground clamp then add another clamp above flo and install existing clamp below flo using same wire.

The metal bonding wire (grounding electrode conductor) from the service panel may not be cut or spliced or jumpered before it reaches the main water pipe at a location within 5' of where the pipe exits the house underground and with all metal from said attachment point to where the pipe exits underground.

Metal bonding wires (bonding jumpers) going elsewhere such as to other plumbing or to an antenna may be shortened, raised, etc. as described previously.

If a bonding jumper that should go to a panel or pipe or ground rod should first reach a GEC it may end and be attached there instead.

You must also treat that bonding wire with care. There have been occasions where there is a lethal voltage on it. As long as it stays connected to ground..... no problem. It wouldn't hurt to use gloves.

Just don't get between the copper pipe and the ground wire.

I always thought the bonding ground wire was supposed to be clamped on each side of the meter / main shutoff.

In older installations it would not have bridged the meter. That was added later in the code.
