Myson compact Bad Humming?
I have a Myson Concentrated Central Heating pump that is humming badly when the heating is on. Anyone know why?
Is the force still running, if the impeller seizes this can cause the humming turmoil. other causes are, bearing starting to wear, draw running dry (check small tank in loft to mould sure it has not run dry). Compacts arent known for there sustained life span. Suggest replacing with a Grundfos.
Sound luck
