Thank you for your interest in Water Pumps Direct. You will need wire and a torque arrestor (you will need to purchase locally) and depending on the depth of the pump installation, you might need a check valve. A splice kit is included with the pump for a water tight splice to your wiring off the pump. You can also check the pump OWNERS MANUAL for additional installation information. The connection on the pump discharge is 1-1/4" however you can add a 1-1/4" to 1" reducer if you prefer as long as your pressure tank is relatively close to the well head.
