hot water circulator pump vibration

[ChristineLondon]

Hi everyone,

My flat is located next to a communal boiler with a hot water circulator pump ( Grundfos UPS 15-50N Secondary Hot Water Circulator ). The pump is noisy and vibrating.
Would installing a more powerful pump solve the problem?
Many thanks for your help!

No doesn’t need to be bigger sounds like the pump needs replacing
