Thanks for the reply's,
I will try to make contact with BW. The water system plumbing is definitely a PEX quick connect system of some type. It has the shark teeth " snap-in" plastic connectors (not brass). I am aware that Shark Tooth is a brand and I do NOT know what brand is installed. I also was able to simply disconnect the cold water line
entering the water heater and plug it, allowing me to use the rest of the water system for the next 48 hours with out any problems.
I trust BW can get me on track.
