New mp40wqd

[gtguy256]

I just purchased two new mp40wqd powerheads and one of them is significantly louder than the other. It is rattling or sounds out of balance. I have tried many times to line it up better but it makes no difference in sound. I have already sent an email to ecotech but I am wondering is this something that will go away with time, and can I run it on low overnight. Or should leave it turned off to avoid any damage?

I had a similar issue the other day with my mp-10. They told me there was a break in period of a week or two. In fairness mine broke in after a day. Good product, but that should be on a card in the box. When you spend that much on a pump, you don't want to hear anything.

Did yours ever quiet down? I just bought a brand new one and it's no quiet at all. I have the right gasket and everything seems to be aligned properly, but it's pretty noisy.

It did quiet down I just ran it at minimum power to start and slowly ramped it up over two or three days. Now there is very little difference between the two power heads.

Good to know, thanks!
