Energy Efficient. Includes (2) 400-4060 unions that accept 1.5" PVC pipe. NOTE: If you are not replacing with the same make and model Waterway pump: There is no industry standard for unions, the various brands have their own unique style and thread size. Which means you must use the unions provided with our spa pump. This will most likely involve cutting off your old unions and installing the new ones shipped with the spa pump. If your heater is directly coupled to the spa wet end, then our pump will probably not work as the union will most likely be different. Be sure to look at the motor voltage, not the voltage supplied to the spa to determine the correct pump voltage. When removing power cord from existing pump we recommend you mark your wires for "common", "high speed", "low speed". The pump does not come with a power cord. The connection diagram for the new pump is located on the motor name plate. The pump head can be rotated by simply loosening the motor thru bolts and turning the pump head, allowing the discharge to point to 3 O'clock or 9 O'clock.Not Self Priming - Water must be above pump head in order to operate properly.
