NOTE about Watkins Wavemaster Complete Pumps: Watkins Does Not Make Pumps. They buy different brands of pumps and put their numbers on them.. If you want the original Watkins numbers on your new pump we don't offer that.. What We offer is the exact pump or the closest equivalent to the original pump if it is obsolete that they would buy and put their numbers on from the original pump manufacturers. The main difference between one you would buy from them now and ours is the exhaust vent in the back will not come on our pump.. We think it is a bad idea as it does not allow the motor to cool as it was intended to cool and does not have any redeeming quality for you as an end user.. See the below picture for what will NOT come on our pump.. If you must have that feature Watkins is the only source..  

Note: If your original Pump has this on the back with a hose attached none of my pumps will have that nor will they be able to accept this part from your old pump.. You will save 100's of dollars over the original pump with that attachment that is only used to put heat from the motor under the tub and I believe the motors stay cooler without that device and last longer..

Read this information to Help to determine the Frame and HP.. The way you can determine whether your pump is a 48 or 56 Frame is by measuring the width of the motor. A 48 Frame motor will measure 5 3/4" wide across the back and a 56 Frame will measure about 6 1/2" wide across the back.

For 230 Volt Pumps Look on the label of the motor for the two amperages if you have a 2 speed pump, if its a single speed look for a single amperage. It will look something like this: 10.0/3.5  The 10.0 is the high amperage in this example.

8.0 = 1 HP

10.0 = 2 HP

12.0 = 3 HP

14.0 = 4 HP

16.0 = 5 HP

For 115 Volt Pumps Look on the label of the motor for the two amperages if you have a 2 speed pump, if its a single speed look for a single amperage. It will look something like this: 10.8/2.8  The 10.8 is the high amperage in this example and would equate to a 1 HP.

  8.0 = .5 HP

9.0-10.0 = .75 HP

10.0-13.00 = 1 HP

13.5-15.0 = 1.5 HP

16.0-20.0 = 2 HP

Note: These Amperages are Averages so find the Amperage closest to your pumps Amperage. Note for the Note: 2HP 115V pumps are very rare, do not order one thinking you can add more power. This pump or even a 1.5HP pump will cause your PLug N Play tub to damage the electrical system, Plug, Wires and even the pump motor.

NOTE: Your pump or motor may say a different Horse Power than what you see here, DO NOT go by what is listed on the motor, go by the amperage on the label.

NOTE for the NOTE: TRUST ME ON THIS, everybody lies about their Horse Power. But the amperage does not lie. Most people are told they have 5 HP pumps, if you do the math two 5 HP pumps at 16 amps is 32 amps. Plus a 5.5 KW heater is 21 amps. That means with both pumps running and the heater on it will draw 53 AMPS. I bet your HOT TUB is on a 50 AMP breaker. Therefore contrary to what you have been told you DO NOT have a 5 or 6 or 7 Hp pump.
