Alterna mixer bar

Hello, my shower runs from the combi boiler. when cold and first used it makes a terrible rumbling/ vibrating sound for about 30-40 seconds. would this be to do with the thermostatic cartridge? The hot water bath tap is connected to the same pipe and doesn't make the noise so it got to be in the shower unit? thanks

I tend to agree with you however I would have to hear the noise for my self to be absolutely sure.

Just have a really close listen to the valve and make sure that the noise is coming from the valve itself and not travelling along the pipe work making it sound like that it is coming from the valve.
