Boiler coming on when we put the cold water on

[Iwasjustasking]

BG changed a part in my boiler Saturday, since then my boiler clicks on Everytime we have the cold water on! I have bg coming back on Friday but is this a common problem, what could it be?

If there is air in your pipes then this can happen. Start with the highest tap in the house and slowly turn it on until it is flowing fast then turn it off. Do this with ever water outlet ie shower, bath taps, kitchen taps, cloakroom etc. Work your way down the house. I also flushed the toilets for good measure! If this doesn't help I guess the engineer will sort it.
