Re: scott atwater water pump problem

I assume this is the curved leg model with the pumps below the powerhead. The water pump on those motor is a stainless steel insert that sits in a cast aluminum housing. I have found instances where corrosion gets under the insert and warps it upward in the center. The impeller makes poor contact with the insert, vacuum is lost, and the pumps will not prime up from the water inlet. Start by checking the pump housing to see if the bottom of the insert is flat.

If it is, then be sure there are no air leaks between the pump housing and the water inlet.
