in my view, a pure infinite ohms bonding system is the best for safety,

I don't know if I would call that a view as much as I would call it a fact.

its just not achievable.

Exactly.

bond it all,

For sure


add some earth rods,

Now you suggesting grounding myths and voodoo. Sprinkling a property with extra ground rods will not increase the performance of the equal potential bonding of a pool.


tie/bond it all back to service gnd (i do not rely on pump frame to be service gnd).

This strongly suggests you do not grasp the objective of the equal potential bonding at a pool. I would also say your statement adds to grounding myths.

bonding to a pump frame does what exactly, in its entirety?
i fully understand the equi-potential "concept", i just dont like the option of being energized to say 240vac even if its all at 240vac, etc. nec suggests equi-pot to reduce some risk, i like that risk to be reduced further.

did you watch the MH video http://forums.mikeholt.com/showthread.php?t=177882

he lifts the N, the earth rods can reduce the voltage found on other metal parts of the structure, which reduces safety hazard.
