Can one of you please straighten me out on the following? I'm replacing my water heater and currently have the copper corrugated lines with the plastic sleeves at the threaded connector as shown in photo. The water heater has lasted 17 years, so things have been good.
I went and purchased new water line connectors which look exactly like the ones I currently have. I'm a bit confused on the following: I inferred that a dielectric break should have zero conductivity (or infinite ohmic value) between the brass threaded connectors and the copper corrugated tube. I expected at least a large ohm reading of some sort. I'm getting 3.3 ohms. Both new corrugated connectors test similarly at both ends. I wondered if it would change position when tightened, so installed it on a nipple and measured as shown.
Is this ohmic value normal, or are the parts defective? Or given the low voltages generated with electrolysis, is such a low ohm value is adequate?
Thanks, Toukow
