Again, if there has not been an issue of water hammer before and there
now is, increased pressure from a stuck reducing valve is a condition to
check. BTDT, didn't print the t-shirt.

I have nowhere said there is any cause other than the cessation of
flow--the deal is, high pressure increases flow.
