Does the basket lid have 2 orings. My lid only has a pressed seal. Looks like it doesn’t come off. Pump won’t prime and the seal has damage so need to replace it. My pump is a sp4007x10ns. Not sure of year it was here when I moved in.
The SP4007X10NS Northstar Pump would only have one lid o-ring/gasket. The o-ring/gasket will depend on the year the pump was manufactured. We have a guide that explains how to identify the manufacturing time period.
