hello clever plumbing peeps!

if when the heating and hot water is turned off we have a VERY audible humming sound coming from roughly where the pump is located, would you recommend we get someone in to check it over/replace the pump asap?

Well maybe if you got someone to service the boiler they can check the bypass in the system is opened/set correctly,the pump will run on after boiler/system is closed down to dispel heat
The loud humming sound is maybe caused by restricted flow
