Gurgling dampen noise when my Central Heating is on?
Answers: As all the previous answers are wrong, I am guessing no plumbers own answered yet! The problem is pump overflow, turn pump speed down, afterwards vent the radiators. This has probably come roughly because of sludge in the system, if it have always done this, later the vent pipe for the feed and expansion container is too close to the pump, other possible is you have have a new pump and they hold fitted it back to front. If not, verbs the system, powerflushing is lb600+ off British gas but lb200 or more cheaper elsewhere. P.S. 'nouns lock is a term used comparatively often when the 'plumber' have no idea what the problem is!
I've freshly had someone to look at mine ,the plumber said it be an air lock hope this help
