Please briefly explain why you feel this question should be reported.
I have a Potterton Suprima 50.
I started with gurgling sounds. A plumber bled the radiators. It went away and then came back. The same plumber replaced the water pump. It went away and then came back again. He bled all the Radiators. The gurgling noise comes from the boiler and not from any pipe. Any suggestions?
