I have had a lawn sprinkler water pump system for the past 20 years.
The pump is installed in my basement, but it uses water from a well
(the rest of the house uses city water). It has worked without a
problem until I recently had a new water well installed with a new
water pump. Since then, every time the sprinkler system is turned on,
it makes a continuous loud rushing noise through the pipes which I can
hear throughout the house. When I put my hand on the pipe, I can feel
it shaking fairly strongly.
When the new well was installed, the size of the pipe drawing the
water from the well was increased by about 1/2 inch diameter (to 1 1/2
inches). I am still using the original pipe that connects it to the
sprinkler system (about 1 inch diameter). I am wondering if this may
be causing the problem. My contractor who installed the system says
he cannot do anything about the noise. Do you have any ideas about
what I might be able to do to solve this problem? Changing the piping
would be a very big job, so I want to see if there is anything else I
can try first.
