OK, let me see! You say that you read a pipe close to the panel and got 0 volts, and about 1 ohm.....right? Well you might want to look at the resistance through the pipes. Sometimes you get resistance through the pipes because of bad solder joints. Check your resistance from the spigot and at the pipe close to the panel ( where you got your readings). I believe that you will see resistance between the two points.
