When replacing a hot tub pump it is recommended to replace the union O-ring as they can develop flat edges from being compressed over the years and when a new pump is installed without replacing the O-ring the union can leak and if over tightened will crack.
The PF- model number from your old pump should not be used as a reference for selecting a new replacement pump as Waterway has produced up to 4 known variations of pumps with the same model number which are different enough that they are not interchangeable. Always select a replacement pump with the same part number as the Waterway part number on the label on your old pump.
Orientation of wet end.
Pump wet end can be oriented in 90 Degree increments, up, left or right. Pump will ship with discharge directed up. To change the discharge orientation, loosen the pump's four through bolts from the back of the motor and pull them back enough to disengage. Then rotate the wet end to the desired position, realign and re-tighten the bolts.
If your pump thread O.D. is (approx.) 3.0", Then you'll need a Pump with union size 2.0".
If your pump thread O.D. is (approx.) 3 5/8", Then you'll need a Pump with union size 2 1/2".
