The best advice is to stop putting “liquid snake” into a fresh water supply line. I assume it is labled not for internal use and how will you be sure you have flushed it all out of the system before someone takes a drink. If it is plugged, and I assume it is a galvanized line, the material clogging it is rust and nothing will dissolve it. At least nothing that should be put into a potable water line. And if you do get it unclogged, you may wind up with leaks since rust is sometimes sealing weak spots in the pipe and once the rust is gone the leak is able to open up again.
