The Waterway Executive 56 4HP hot tub pump has two speeds and features a split capacitor for both starting and running, which helps reduce energy consumption. It is thermally protected to enhance the motor's life expectancy.

The pump runs on 220-240 volts and is rated for 12.0 amps on high speed and 3.5 to 4.4 amps on low speed. This Waterway executive 56 frame 4.0 HP pump has a side discharge with the larger 2-1/2" threads on the intake that measure about 3-5/8" across outside.

IMPORTANT

The PF- model number 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 or replacement part number as the Waterway part number on the label on your old pump.

The last digit "C" or "M" in the model number only references the brand of electric motors Waterway uses on these pumps and does need to be matched on the new replacement pumps. C references Century/A.O. Smith brand motor and M references the new brand electric motor on the pump. The low speed amps can also vary depending on the motor brand from 3.5 to 4.4 which has no impact on performance.

Horsepower ratings

Choosing a pump based on Horsepower (HP) can be incorrect. The horsepower listed in your spa manual or on the old pump's label may be overinflated, inaccurate, or even left blank. Horsepower ratings on hot tub pumps are often listed as SPL-HP, BHP, MBHP, RHP or S-HP, which is not the same as continuous operating horsepower. Installing an oversized pump in your hot tub can cause significant damage.

To avoid choosing the incorrect pump, confirm if it’s a 48 frame or 56 frame, then use the high-speed Amperage rating listed on the old pump's label to find the correct replacement instead of the horsepower. The amperage rating is listed with both high/low speed for a 2-speed pump.

Determining hot tub pump thread size

Hot tub pump plumbing sizes are nominal and not the actual outside diameter (O.D.) of the threaded intake or discharge. To confirm your old pump thread sizes, use a tape measure and check the diameter of your old pump thread size.

  • 1.5” Pump thread measures approx. 2-3/8” Outside Diameter
  • 2.0” Pump thread measures approx. 3” Outside Diameter
  • 2.5” Pump thread measures approx. 3-5/8” Outside Diameter

Amperage ratings

New hot tub pump amperage ratings may vary slightly for pumps with the same performance rating. The RPMs remain the same 3450 for high-speed and single-speed pumps and 1725 for low-speed for two-speed pumps.

Excellent service & Support

I recieved my product in a few days. Upon arrival I noticed that the pump wasn't quite the same as my original so I called and left a message as it was after hours. A service tech called me shortly after 9am the following day and answered all my questions and confirmed that confirmed that this unit was compatible with my spa pack. Everything is work well for over a week now.

The replacement pump that was the same brand but another replaced by a new number but was supposed to have the same spect have just a Little more flow and created too mutch back pressure . Overtemp trip all the time , my spa did not work from the begining of this summer and pool supply tell me that it’s not the pump that cause this problem , was working for 10 years . Impossible to understand that and do not want to understand and help me . That was my last time to but from them !! The new pump flow more and i lost money , your system do need t match correctly !

Hello Jean-Nicolas,

We understand your frustration and will gladly help if we can. Both replacement pumps sent to you are the exact same Waterway brand direct-replacement models as your old pump.

Your old Waterway pump featured an A.O. Smith electric motor, which Waterway has not used in many years; therefore, ordering a replacement with that specific motor brand is no longer possible. Your original pump had a factory high-speed flow rate of approximately 240 GPM. Both of the new Waterway pumps you received are direct replacements for your old unit and provide that exact same 240 GPM flow rate. Based on the pump specifications, it is technically impossible for the new pump to have a higher flow rate that would cause it to overheat, unless your old pump was altered and has a smaller impeller it it. Since you mentioned the plumbing was modified right before the pump began overheating, the logical conclusion is that those plumbing modifications are restricting the water flow.

While we are happy to assist you with the pump itself, our technical support does not cover external plumbing issues. To ensure proper water flow and protect your equipment, we strongly recommend having a qualified pool service tech inspect and adjust plumbing system for the flow rate of the pump.

Please don't hesitate to reach out if we can be of further help. John or Jackie in tech support at: parts@poolhtd.com

Nice Pump tight bleeds

I installed this pump and it is great. It is quiet & powerful. Shipping was fantastic and arrived within days. Only problem I had was with the air bleed nuts. They were so tight & had no cut for a screw driver. They are 7/8” but I could not find a socket to fit. Had to use a wrench and cut it short because of space limitations. No instructions for starting pump, so I only filled one side with water and opened other bleed holes. It did not pump, so shut it off and poured water in through the two other bleed holes. No cuts on the threads on the bleed nuts so it was painful opening the bleeds fully in an awkward position. Could not do this quickly, so had to turn pump off to open bleeds and close once Air was removed. Good fast delivery and a great pump.
