I have just installed a new single lever mono mixer tap in the kitchen. A combi boiler is installed. The hot water works fine but when any of the cold water taps in the house are switch on and then off the combi boiler will fire up for a very short period as the tap is switch off!!!
Would fitting non return valves on the new tap solve this?
All feedback appreciated
