"Water Hammer" Turning Faucet "ON" ?

[Robert11]

Hello,

Have the typical Delta single-handle faucet for the kitchen sink.
At least 10 yrs old.

Has the single good size ball type of valve inside the handle.

Whenever we turn it ON, the hot or cold, there is a big "bang" in the pipes.
Noise seems to truly originate in the faucet, but not 100% sure of this.

Am tempted to call it a water-hammer, but I always thought water hammer, in the true sense of the word, was only when one closed a valve, and the ensuing pressure wave due to the running water being shut, suddenly, caused the hammer. Is this true ?

We have no problem when shutting; only when turning it On.

Anyway, I replaced the small hot and cold top-hat rubber seals and their
springs. Also replaced the faucet's main ball-valve/handle, and the small Diverter valve that controls flow to the hose-sprayer.

No change. Still happens.

So, in effect, I guess, it can be considered a pretty much new valve.
Nothing more to replace anymore; I think everything replaceable I
have done ?

I can buy a new valve of course, but hard to see the difference in a new one compared to the one I have now, now that it's been "updated" with the new components.

This is really driving me crazy, and more important the wife.

Any thoughts on this would be most appreciated.

Thanks,
Bob

Hi When shutting of very slowly does it still produce the noise?

Hi,

Thanks for help; appreciate it.

Turning it on, fast or slow, produces exactly the same result.

sounds like somthing isnt opening when you lift the handle and the pops of its seat by the preasure of the water if had this when the washer on a tap is so worn it sticks in the seating
