If you are using it to pull water from a water source then yeah that changes things, maybe, but in OPs case the pressure from the volume of water in his storage tank permanently negates any need for prime or to ever think about it.
Maximum suction head for the OP's pump is about 9 meters so yes a shallow well.

Yes the OP's installation has a water tank and yes he lives in a single storey house so he doesn't really need a check-valve spring but there was one supplied and the "contractor" had no real need to remove it. Without the spring there is a slight delay, enough to induce water hammer in a different installation.

One could argue that the force required to overcome the spring does detract from the pumps total output but not enough to worry about.
