I am building our home and doing rough plumbing at the present time. I installed a manifold of six 18"
long hammer arresting chambers on my water service line immediately after it enters my basement. I've
since discovered that our local plumbing ordinance require the installation of a pressure regulator where
water pressure is in excess of 70 psi (I have 75 psi). I would like to install this in the basement as well,
but my setup is such that I would be forced to install it downstream of the hammer arrestor manifold, that
is, between the manifold and all valves within the house. Does the installation of the regulator in this
position defeat the purpose on the hammer arrestor manifold? I'm thinking the pressure wave caused by
an abruptly shut valve in the house would bounce back and forth between the regulator and valve, and
the air trapped in the hammer arresting chambers would never be afforded a chance to absorb some of
the wave's energy. What do you think?
