cqmart, It helps if you fill out the location in your profile. I found these links on an advanced altavista search. "exact phrase" clayton mark, "must contain" hydrant
Clayton Mark has been bought out by American Grandby. Phone # 315-451 1100. They have distributors in most states. My yard hydrant had 2506k on it, but that was just the handle assy. I was told. The repair kit for mine is YRK1.
Good Luck. Jim [img]/forums/images/icons/smile.gif[/img]
