Mixet shower valve - and recent water hammer

[Lbjgh]

I recently replaced an old mixet shower valve on my shower/tub. Before installing the new valve I used a circular brass brush to clean the valve body then I lubricate the new valve orings with vasoline.

The operation seems smooth... all good I thought.

But... when the toe tester valve is closed I get a loud water hammer bang that I don't recall being there before (or maybe not as loud). Nothing else has changed and the water pressure is what I'd describe as on the lower side i.e. about 55-60psi.

Any insight would be helpful to reduce or eliminate this water hammer.

A link to the valve your talking about would help. Also don't use vasoline to lube o rings.

It sounds like your valve is closing faster than it did before which is the cause of water hammer. A hammer arrestor would fix the issue. They are installed as close to the closing valve as possible.
