hi folks hope someone can help me. i recently had a council gas engineer out because i had shuddering pipes and boiler was kettling he changed the pump over the shudder was still there so he came back yesterday and fitted a new bypass and a external manual bypass (whatever that is).the shuddering pipes has stopped but i noticed later on that night when i was in bed the boiler started making a weird noise( like kettling/ or coffee perculator) when it fired up and going thru a cycle ive recorded the noise on my phone and emailed to my computer.if anyone wants the mp3 to hear it send me an email address i can forward the file to. hope someone can help out with this its driving me berserk the last 15 seconds is when you hear it most
