Hello to all. For the past few months we have been getting loud banging from under the kitchen floor just before the boiler kicks in. Is so loud that you can feel it. It only realy started after a vaillant engineer came out to replace a leaking valve on the central heating flow out pipe at the boiler. I bleed the radiators twice a month and each time theres air in the same two radiators. Not much, just a small amout. All the radiators get warm with no coldspots.
The stopclock is under the sink in the kitchen and if you hold the pipe that runs to it when the noise starts u can feel the whle pipe kick.
Any ideas or fixes.
Many thanks Darryl.
