[Shop-talk] Seasonal water hammer?

[Larry Spector]

I've got an odd problem, and it's been going on for a couple of years now.
Every fall, when the cold water supply (county water) starts getting even
colder, I get water hammer. I can usually get it to go away by turning off
the tap and turning it back on slowly, but it's a pain to deal with.

Any idea what may be causing it and what can be done to alleviate it?

Thanks,
Larry
