Good To Know

Q: Does this housing include the impeller and wear ring? A: No, this listing covers the jet pump housing only, so the impeller and wear ring must be sourced or reused separately.

Q: What signs show the pump housing needs replacing? A: Cracks, heavy scoring inside the bore, or corrosion along the sealing edges are the usual indicators that water is bypassing the impeller.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
