Deep,

Waste asked me to help you with some of your problems with rust. I hope I can help.

The fact that you can blow water on the rust parts and mainly the screws, seems to indicate an incompatibility with SS and the screws. The screws should be identical in grade as the SS with which they are in contact.

As regards the bonding, everything should be bonded, but I defer this to our "electric wizards" who can help you further.

The SWCG will have to run much as Waste suggests, but not knowing the pool size and SWCG make, it's difficult to give an acceptable answer.
