Bought a MP10QD and went to set it up yesterday and it's making this god awful noise? It's definitely coming from the motor... Has anyone else experienced this? Sounds louder then a 3-4 year old Mp40! I read a few things from a quick Google search but nothing helped. I tried unplugging it and I've had it on low speed constant mode since yesterday. I read online that Ecotech recommend this when the QD pumps first came out? Idk I thought these were supposed to be completely silent? Any help would be greatly appreciated
