New Weipro pump very noisy

[cdckjn]

I am using a Weipro 2014 skimmer. It was fitted with a Dymax 4000 but the impeller motor was wearing away. I bought a new Weipro 9000 pump.

When I put it into the sump (not connected to the skimmer) the pump runs quietly. As soon as I connected the skimmer to the pump, the pump becomes noisy. Any suggestions to solve the noise problem?

Thanks.

Cannot be help bro. Weipro pump and skimmer are noisy.

You should get Ehiem or Aquabee pumps...these are low noise high performers.
