When we built a house in California, it was standard to put a pressure
reducer in the line to the house lest the force do real damage.  Reason was
that this had been a rural area using a lot of water for groves and the
pressure was designed for mass delivery.  Worked fine for the avocado trees
and no real problem for the house as long as the house plumbing addressed
the problem.
