apart from flooding your house a little and damaging your electrics on your boiler,get a corgi reg installer to do the repair (this is the law) ,you could do damage to your self or somebody else.but changing the pump is easy,drain boiler by loosening drain point under bolier white knob,keep a bucket underneath,this will let all the water out of boiler,make sure to fully drain boiler before removing pump,fit pump,tighten drain off,refill boiler
