Thanks to all for the suggestions. We finally had a dry day, so got'em wired up. Cut each strand at its respective valve. Tested, work fine. Thanks again. Frank.
When running multi-strand cable to several valves, which are not located in the same valve box, should you cut the strand you are using for each specific valve so that the power is not available downstream? If not, at the end of a 7-strand run, how do you keep the end strands from touching each other. Electrical tape would not be enough, since it would not be waterproof. Using a waterproof connector on each of the five unused strands would work, but seems wasteful. Comments?
