Hello there,
Last night my DDC pump started making some very odd noises.
It sounds like a crackle and poping sound its also intermittent aswell.
Temps are fine and there is no discolouration to the mayhems pastel green. (Please dont judge me :p)
The system was rebuilt and cleaned out a year ago. The pump must be about 3 years old.
There is also no foaming either. Could the pump be on its last legs ?

Thanks
