Hi Betty,

How close is it to your living or sleeping area?

Yeah, sure. Same as the old one. Made in the same country with the same
windings and electric control board. Sure...

Can you tell if the problem is a magnetic field from a motor, or a RF
problem from some electronics?
or even a dirty electricuity kind of RF problem is another possibility.


Quite frankly, I get better results using Avoidance, and Replacement of
components until satisfactory. In this case, I would need to know more
about the pump to come close to a "final answer" for you.
I doubt will be easy to replace the pump with a quieter model... and
while you may achieve some reduction with grounded carbon absorber and
aluminum foil, etc. I doubt it wll be the same.

My best advice is to ask how you feel on the opposite side of the house?
to determine the range of the problem, may help identify the specific
irritant.
