Severe Water Hammer Just Started

[brantdavis]

I live in a triple-decker condo built around 1909. The third floor condo just replaced their entire bathroom. While it may just be a coincidence, the pipes feeding their unit have had a LOT of water hammering since the work was done. This is especially true with the hot water where the noise is especially loud at the water heater in the basement (I live on the first floor and am the one who gets the brunt of the noise at 5 a.m.!!).

Any thoughts on how to fix this other than with arrestors? As an FYI - their plumber wants to install water hammer arrestors. This seems unnecessary since there was not any issue at all before the work began.

Also, does anyone have any ideas on why this would it start just after the construction? Thanks...
