We just had some kitchen renovation done, adding lighting cans to the
ceiling. The contractor had to reroute some of the waterlines that
were run up there to make room for the lighting fixtures. Only thing
is, now the pipes make a kind of loud shudder when the kitchen faucet
is turned off. *Didn't used to happen. *What's the cause of it and
what can we do about it?

was the kitchen faucet replaced with a different unit? or just the
can lights?

add water hammer arrestors at the hot & cold angle stops under the
sink

turn the water off more slowly when using the kitchen since

have the contractor property restrain the re-routed pipes

cheers
