The PVC pipe coming out of my well is 1 1/2. " The suction port in the
pump is 1"threaded .
I need a male 1" thread to screw on the pump. On the other end I need
1 1/2" female to slip on the well piping.

I've searched Home Depot,Lowe's, and cannot find this type of adapter. Is there any
Alternatives?

The discharge port I have the fittings. Thanks to you wonderful
Guys with your advice.

1 1/2" coupling, 1 1/2 X 1" bushing, 1" pipe, 1" male adapter.

Use a PVC bushing under couplings to get to 1", a short piece of 1" tubing and a 1" slip to 1" male adapter.
