How Things Measure Up
Throughout our catalog you will notice that all the plumbing parts as well as pump parts and other items are referred to as 1/2", 3/4", 1", 1-1/2" or 2". Yet when you measure "across" the fitting you don't come up with any one of these measurements. It can get confusing. So Instead of trying to explain why, we have put together a list of our most common items sold and listed there "spoken" measurements as well as how they really measure up.
"OD" = Outside Diameter
PVC Pipe and Flex Pipe
Wet ends; also referred to as pumps, is the plastic molded housing that
is mounted at the end of the motor. It has two port connections, one being
the suction and the other being the
return, which can be rotated 360 degrees. Both these
ports have plumbing attached to them via connection of a union or quick
disconnect. Pump/ Wet Ends come in various styles and shapes, they are sold
as 1-1/2", 2" or 2-1/2". The 2-1/2" measurement is typically found on the
suction side only. Measure the Outside Diameter of both the inlet and outlet
to confirm what size wet-end or pump you will need to order.
