Hi all,

Recently had our boiler (Vogue Gen2 C32) serviced, and two non return valves and a shock arrestor installed due to boiler firing up when cold water was turned on/off quickly. Since then we intermittently get the attached noise from the boiler. I've tried a couple times to replicate the
noise, but it doesn't seem to be associated with any particular scenario (for instance when running hot/cold water, upstairs or downstairs).

Unfortunately due to this I've struggled to get a video for any extended period of time, but have attached a short clip of the noise. Was wondering if anyone has any idea of the cause, especially if it's just a vibrating pipe, before I get our plumber out... Thanks!

 
Pressure vessel not set to the mains pressure

You can try removing the dust cap and depressing the shrader valve for a mil second eg release some air and see if it changes etc
