| Go to the Sears website and look up: "shallow well jet package". You will find a device that attaches to the front of the pump you have. Once it's attached, you'll have a 1 1/4" inlet and a 1" outlet.
A jet assembly only has two main parts: a nozzle and a venturi tube. We can talk all day about how it works, but I'll try to keep it simple.
After the water leaves the impeller, some of it is directed back to the jet assembly, under pressure. As this water passes through the nozzle and then the venturi tube, it's velocity is increased, which increases the pressure entering the impeller. If you increase the pressure of the water entering an impeller, the impeller is able to add that much more pressure to the output.
This is why adding the jet assembly to your pump, will increase your discharge pressure to the house.
Jet assemblies are engineered for each pump, so you'll need to buy the one that's designed for your pump.
