Huh?
Plastic pipes do not carry current, they are non-conductive. There is nothing to bond to, and no need to bond to nothing (nothing to bond to).
I can't see reducing the call for bonding a pump connected to plastic.
Huh? See above.
At least with bonded metal pipes, you have an alternate path if the pump ground fails, not so with plastic.
"Bonding" *IS NOT* to provide "an alternate path" for ground current. "Bonding" is simply to tie all associated metallic parts which are in contact with the water together. Being as (with plastic pipes) there *is only one* metallic part (the pump), there is nothing to bond together.
If you have a plastic pump housing with nothing to bond, then you can't bond it anyway. Those systems typically have a double insulated motor with a grounding wire from what I see.
Well, at least you got that one.
Question #1- Can you conceal a cord and plug connection behind an access panel (not READILY accessible)? (of course we would never know if we can't pull the panel, so it is mostly academic)
Cords and plugs are not allowed to be where concealed, which is *just one* of the reasons that panel as to be accessible without damaging the building structure or building finish. There is no requirement that it be "readily accessible", a term which is defined in the code.
Question #2- Has anyone else heard of the change in the newer codes requiring READY access to hydro therapy tubs?
Not in the 2005, I should be getting my 2008 soon (I hope - it's been on order awaiting publication of the 2008 NEC).
It's always just been 'accessible without damaging the building structure or building finish'.
