We have provided information on this page to help you make an informed decision regarding spa pumps.
Please review this information carefully. If you have questions please call us.
| Note: There is no industry standard for Unions. The various brands have their own unique style, which means you must use the unions provided with the spa pump. This will most likely involve cutting off your old unions and installing the new ones shipped with the spa pump. This is why we include the nipples and couplers. To make adaptation easy. (Hardware stores do not sell these PVC couplers). 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. | ||||||

1.5" and 2" refers to
the size of your PVC supply plumbing lines. It has nothing to do with the size of
the union nuts or the size of the threads on the wet end. Do not determine the size by the inside or outside dimensions of the spa pump head inlets/outlets. You must measure the PVC supply lines. The PVC pipe slides into the union and is glued with PVC cement. 1.5" plumbing means you have 1.5" schedule 40 PVC supply lines (1.5" I.D.; 1 7/8" O.D. on the line) circumference = 6.5" (wrap a tape measure around the pipe) " plumbing means you have 2" schedule 40 PVC supply lines (2" I.D.; 2 3/8" OD on the line). circumference = 8" (wrap a tape measure around the pipe) Note: Some lines are hard PVC and some are flexible lines, but have the same size O.D. |

Be sure to look at the
motor voltage, not the voltage supplied to the spa to determine the
correct pump voltage. These are full size pumps and motors - Not the smaller circulating pumps - Take a look at our Iron Might Pumps for circulator pumps. When removing power cord from existing pump we recommend you mark your wires for "common", "High speed", "low speed". The connection diagram for the new pump is located on the motor name plate. If you are unsure as to whether the pump will work for you, call us and we can discuss it with you.

| The wet ends can be
rotated by simply loosening the motor thru bolts and turning the pump
head, allowing the discharge to point to 3 O'clock, 9 O'clock or 6 O'clock. If you tell us we can do it for you. We determine direction by looking at the face of the pump.

FAQ: Can I change my spa pump to a larger horsepower pump? Answer: Yes, most cartridge filters have a bypass valve, so that the increased water flow will simply bypass the filter and flow through the lines into the hot tub. The water will still be filtered when the spa pump is in low speed speed mode. FAQ: Can the pump head be rotated? Answer: Yes by loosening the (4) motor thru bolts, the pump head can be rotated to any position. Then you would simply re-install the thru bolts.
