TRV (valve body) vibrates when modulating central heating water flow
Apologies if this is covered but I have an annoying and noisy problem. Having fitted a Drayton TRV to a newish valve body (approx 5 years use), I am getting a hammer action when the valve set point is close and I think the TRV has partially closed the valve to reduce water flow. Any ideas? Thanks
