Is a 15 feet developed length from the branch T to a frost-free hose bib that is not used in winter a dead end? In the Chicago area the hose bib has not been used since November; it is early March now. I have to do some other supply work anyway, so should I;
1) Leave the branch alone,
2) Install a stop and waste within 2 ft of the beginning of the hose branch, leaving the other 13 ft drained all winter, or
3) Create a supply loop to within 2 ft of the hose bib valve, then run it back to the kitchen group, the 3rd side of the current T. This would flush the line all year.
Thank you for your two cents.
