The single handle kitchen faucet never had the hammer until the licensed
plumber replaced the washers to stop a leak. What would cause this to
suddenly become an annoying problem? The plumber is "slow" in returning to
check out the problem. Thanks for any ideas.
the new "washers" in the single handle faucet perhaps allow the faucet
to shut off the water flow quickly & thus trigger the water hammer
either shut off the faucet more slowly, in a controlled fashion
have the plumber add some water hammer arrestors at the kitchen
faucet shut off valves
Unlikely that the action of turning the water back on after the
plumber replacing the tap washers any water hammer arrestors, if even
existing, would have filled them up with water. So a suggestion.
The new washers are doing what they are supposed to; shutting off the
water firmly and completely. Whereas the older one were leaking/
However the proper way to operate the taps is not to 'snap' them off
suddenly. Turn down gradually, then off.
Also has any thought been given to why the washers were leaking?
Was it neglect? Or just normal maintenance? Because they do wear out
over timer, especially the hot!
Also is the water pressure rather high, thereby contributing to water
hammer if the taps are turned off too suddenly? Rather like pressing
the brake on a car and expecting it to stop immediately and suddenly
without any jerking or skidding!
I was referring to adding "real" water hammer arrestors; either piston
type or diaphragm type NOT those silly, useless lengths of pipe above
the angle stop.
I was further assuming that no "real" water hammer arrestors existed
in the installation. Small add-on / washing machine arretors could be
easily added by the OP (if they are at all handy).
Those pseudo arrestors (short pipe lengths above the shutoffs) do very
little to mitigate water hammer even when first installed (or
drained). Additionally they "water log" very quickly & lose even their
minimal utility quite soon.
