Default Water spike problems in my house.

What I would guess is: The dynamics of the reducing valve maybe too slow in
getting to its steady state regulating position. With no flow the valve is
in a closed position. When there is a sudden flow demand (opening a faucet)
the valve moves opens to provide flow but actually overshoots its steady
state position. For whatever reason it then slowly closes down to regulate
the pressure. It's during that time frame that there is high flow out of the
faucet. In high performance systems, PRV are fast acting with time
constants in the order of 15-20 millisecond. There are many things that
slow down the transient response of these type of valves--in many cases it
is getting the control pressure to bleed down allowing the valve to respond
quickly Usually a damping orifice being too small is one reason.

Just what people need here is more phyco babble bull**** to confuse
people even more. When all that was really needed was a plumber with a
gauge and a little knowledge on how to use one.
Instead you got a plumber that replaces things because they look old so
it must be bad theory.
