Bryan, I would like to send you a known good and quiet pump to try
out. No $ requested, just to see if it also makes noise. If it does,
then you know something is wrong. I couldn't live like that for at
least two reasons....number one, the noise would drive me crazy and,
number two, it would drive me even more crazy, because I would KNOW
something is wrong.
Miguel
