Anyone who has dealt with a flood in their basement understands the importance of having a water pump on standby.

Inlet and Outlet

Simply put, no matter what size the inlet/outlet size of the pumps are, they all operate in the same manner. The water pump draws in a certain amount of water through an intake valve and expels it through a discharge valve, respectively. The amount of water sucked in and discharged grows in direct proportion to the size of the inlet and output.

Pumps typically have an intake size ranging from 1 to 6 inches, but the size might be greater than that in some situations.

When a pump is turned on, the discharge head (also known as static height) is measured at its highest point in the pipe.

The discharge connection on the Superior Pump 91250 1/4 HP Thermoplastic Utility Pump is 1-1/4 inches NPT. It also comes with a garden or water hose adaptor that is 3/4 inch in diameter.
