Tom- this is a code issue and I don't know if you are able to have access to a National Electric Code book or not but if you go to the local library and look in the 2002 edition of the National Electric Code Book published by the National Fire Protection Association and look on page 104 and page 110 there is considerable information that would have us grounding to the water piping system and including all piping systems, on the premise. As for electrolysis, you will have that whether or not you hook your ground wire up to the piping since electrolysis is a DC phenomenon. You might improve the situation if you ground it [Linked Image] The well drillers quite often use that as an excuse for not allowing the electrician to ground the submerged water pump. A myth at best.
