The Wayne sump pumps are popular for do-it-yourself-homeowners.
Not all Wayne submersible sump pump models have the same specifications and not all homeowners need the same specs. We are here to help you identify your needs and discover the best Wayne Sump Pumps Model to meet those needs.
Understanding the Wayne primary sump pump features is key to finding the best primary sump pump.
What Are The Common Specifications?
All Wayne sumersibles have top suction and no bottom screen. Since they do not have a vortex impeller they are not capable of handling solids.
Some parts are imported, but the pumps are assembled in the USA.
The tether floats come with a piggy back switch which makes it possible to run the pumps automatically or manually.
Motor power cords are eight feet in length.
The discharge port size is one and one-half inches.
A built-in check valve does not exist.
All models have a thermoprotection override which shuts the pump off if the motor gets too hot.
What Are The Unique Specifications?
To understand the unique specifications, let's look at six things.

Three kinds of housing material are used: thermoplastic, stainless steel and cast iron. Cast iron is more durable. Thermoplastic will warp, crack and break after extended use for long heavy pumping. For this reason three-quarter and one horse power pumps have cast iron or stainless steel housing. Though cast iron is used for some models, the cast iron used in Wayne submersible pumps is not the same grade and thus weighs one-half the weight of a Zoeller sump pump; but it gets the job done.
SPT33, SPT50, SPF33, SPF50, WST33, WST40, WST50, WSF50, and RSP130 (discontinued) have reinforced thermoplastic pump housing.
CDT33, CDT50, CDU790, CICDU790, CICDU800, and CDU800 have cast iron housing.
CDU980, CDU980E, and CDU1000 have stainless steel pump housing with a cast iron base.
Four types of horse power are available: a third (1/3, 0.33), half (1/2, 0.5),three-fourths (3/4, 0.75) and one (1 , 1.0). The greater the horse-power, the more pumping capability. Too much can be as bad as too little. If the HP is too small, the pump will not keep up with the water volume entering the basin. Too much HP will cause the motor to run in short cycles too frequently and result in motor burn out prematurely.
The amount of horse power needed is determined by knowing how much water must be pumped during heavy rains and how high and far it must be pumped. To measure how much water needs to be pumped, take a yardstick, put it in the basin and see how many inches come in the pit before the pump runs. To know how high the water must be pumped, measure the vertical height of the discharge pipe and the horizontal distance.
WST33, SPT33, SPF33, CDT33, CICDU790, and CDU790 are 1/3 horsepower.
WST40 is two-fifths horse-power.
WST50, WSF50, SPT50, SPF50, CDT50, CDU800 and CICDU800 are one-half horse-power.
CDU980 and CDU980E are three-fourths horse-power.
CDU1000 is one horse power.
Two float switch types are used: the piggy-back tether and the vertical. The tether float has more negatives than the vertical float.
The tether float takes more basin diameter than the vertical because the tether gives the float freedom to move in and out and up and down. In fact it requires around three inches more. It can get caught more easily because the float and tether move freely in the water. One advantage the tether has over the vertical is that its swith ON and OFF point can be adjusted by about two inches.
The vertical float is advantageous because it takes less space in the pit, is protected from getting caught against the side of the basin because of the switch guard, and usually lasts longer.
WST33, WST40, WST50, SPT33, SPT50, CDT33 and CDT50 have a piggy back tether float requiring thirteen or fourteen inches of diameter.
WSF50, SPF33, SPF50, CICDU790, CICDU800, CDU790, CDU800, CDU980E, CDU1000, CDU980, CDU980E and CDU1000 have a vertical float switch and thus require a ten or eleven inch pit diameter.
Pumping performance is extremely important because it indicates how much water can be handled within a specified time period. Pumping capability is associated with horsepower. It is important to review the Pumping Perforance chart provided by Wayne Pumps. The chart indicates how much water a specific model can move from the pit in a minute and or an hour.
The greater the vertical height of the discharge pipe coming from the pump-port, the smaller the amount of water that can be pumped in one minute. Vertical height, elbows and check valves cause gravity and friction interference with the water flow.
Here's the pumping performance of Wayne's models at a ten foot vertical lift height:
0.33-HP: WST33 (2130-GPH), SPT33(3360-GPH), SPF33(2718-GPH), CDT33(3060-GPH), CICDU790(3060-GPH), and CDU790(3060-GPH)
The length of the warranty is related to the type of pump-housing used. Thermoplastic cannot handle heavy continuous pumping. The three-quarter and one horseposer pumps have the longest warranty because the motor is stronger and the stainless steel housing and cast iron base are more durable.
The WST33, WST40, WST50, SPT33, SPT50, SPF33, SPF50 have a one year warranty.
The CDT33 and CDT50 have a two year warranty.
The CDU790 and CDU800 have a three year warranty.
The CDU980E, CDU980, and CDU1000 have a five year warranty.
The shut off head measures the point at which the pump will no longer remove the water.
To use the shut-off head measurement it is necessary to know the combined length of the discharge pipe both vertical and horizontal of your pumping system. If your systems measurement in feet exceeds the shut-off measurement provided by the manufacturer, the pump will not work for you.
CDU800 and CDU980E have the greatest shut-off head of 26 feet
WST30, WST40, WST50, SPT33, SPT50, SPF33, SPF50, CDT33, CDT50 EE980, CDU790 have a shut-off head between 20 and 23 feet.
Tips Before Buying The Primary Wayne Submersible Sump Pump
What To Decide Before Buying: Do you want a submersible or a pedestal (motor sits above pit on column)? What is diameter, vertical height and horizontal length of discharge pipe? How much water enters the basin within what time period during heavy rainstorms? Which switch type will fit and work best? What about pump housing material? (cast Iron is more durable than thermoplastic.)
Where To Place: The primary Submersible Pump must sit in a basin because the base and impeller volute needs to be submersed in water. If the pump runs when the water is below the impeller or base, the motor will burn up. Wayne does not make pedestal primary pumps which sit outside and above the basin.
Power Source: The primary pump is the main pump. Itrun on electrical power because that is the cheapest and most reliable source of energy over long periods of time.
How It Works: The submersible pump has a float switch which moves up and down (vertical) or up and out and in and down (tether) as water enters and leaves the pit. When the float reaches a preset height, the switch is activated which turns the pump motor on. When the water wanes below the float off point, the switch turns the pump off.
Multiple Uses: If placed in a catch basin or pit, it can be used in a crawl space, laundry room and other locations.
When Not To Use It is not designed to handle debris and waste solids. Nor is it designed to be a utility pump.
Installing a Wayne sump pump is easy. There is no need to hire a plumber. Obviouly the easiest installation is replacing and existing sump-pump with another one that is the same model. Here are the nine installation steps.
1) Unplug the existing pump.
2) Remove the baskin lid.
3) Loose the bottom portion of the discharge pipe from the check valve enough so the pump can be removed from the basin. Watch out for the water that remained in the pipe.
4) Check the bottom of the basin for debris and small pea gravel. Remove it.
5) Unscrew the pipe and male adapter from the old pump discharge port.
6) Clean the discharge pipe and adapter and screw it into the new sump-pump.
7) Place the sump-pump in the basin.
8) Connect the pump discharge pipe to the check valve. It is always best to replace the check valve when a new-pump is installed.
9) Plug the cord into the wall socket.
10) Fill the pit up with water above the float to test for proper operation.
11) If the pump works and there are no leaks, put the lide back in place.
12) You are done. It is that simple.

Wayne Sump Pump Parts
Wayne Sump Pump parts are readily available online through Amazon. Why discard a pump when the float switch fails and the motor and housing are still good? Replacing a switch is easy, economical and eco-friendly.
The following Wayne sump pump parts are available.
The Switch - Part Number Wayne 56395 for the CDU, SPT and SSPF models.
The entire top unit above the housing which contains a new switch,switch-guard and power cord. Part Number Wayne 60017-001 or 60017-WYN1. This is the easiest way to place the switch because it is already attached in the new top. According to Wayne's Installation manual this part is to fit SPF33, SPF50, SSPF50, CDU790, CDU800, CDU980E, and CDU1000.
Location: The Battery Backup Pump sits in a basin with the primary pump. It can also be installed inline with the discharge pipe above the primary pump.
Power Source: The battery backup runs on battery (12-volt DC) power. Batteries have a limited run time before depletion therefore it is important to choose the best based on your needs.
How It Works: The battery backup has a reed float switch which moves up and down (vertical) as water enters and leaves the pit. When the wires in the float switch are close together, the circuit is closed and a signal is sent to the controller to run the pump.
When Not To Use: It is not to be used in place of a primary, It is to be used only for emergencies when the primary pump fails or the electricity fails. It has a pumping performance comparable to a third horse power primary. In addition, the battery has limited pumping time because the battery will become depleted of charge.
Specification Considerations: What will fit in the basin? How much water will need to be pumped during heavy rainstorms if the primary fails?
Location: The Combination Sump Pump comes pre-assembled with a primary and battery backup sump pump. Knowing the dimensions of the pre-assembled pumps and the size of the basin are crucial because the pre-plumbed assembly must pit into your basin.
Power Source: The primary pump runs on electricity and the battery backup runs on battery (12-volt DC) power. Batteries have a limited run time before depletion therefore it is important to choose the best based on your needs.
How It Works: Both pumps is operated by a float switch. The float rises and wanes with the water level. When the float closes the circuit. the switch is engaged and the pump is turned on to run. When the water lowers, the curcuit is open and the pump is turned off.
When Not To Use: It is not to be used if the sump basin is too narrow and not deep enough. Since the combination includes both pumps, it will be necessary to remove the exisitng primary and backup pumps. If you wish to continue use of the existiing pit pumps, the combination will not be appropriate for your pumping needs.
Specification Considerations: What will fit in the basin? How much water will the primary and backup need to pump during heavy rainstorms?
Location: The Sewage Pump is placed in a pit with a bolted down cover. Thje discharge piping is at least 2 inches in diameter and both a discharge pipe for the waste and vent pipe for the fumes and gases.
Power Source: The sewage pump runs on electricity.
How It Works: The sewage pump is operated by a float switch. The float rises and wanes with the sewage and water level. When the float rises and closes the circuit. the switch is engaged and the pump is turned on. When the water lowers, the float lowers and the circuit is open and the pump is turned off.
When Not To Use: A sewage pump could be used in place of a primary sump pump; however the cost of a sewage pump is significantly more; therefore it would not make sense unless the debris in the basiin is larger than what an effluent sump pump can handle. Must know how far the sewage is being moved and how much horsepower is required.
Specification Considerations: What is the diameter of the existing dischage pipe? How high and far does the sewage need to be pumped? Will other materials besides sewage get mistakenly flushed? (Grinder pumps handle anything.), What kind of float switch? What about pump housing material? (cast Iron is more durable.)
Location: The Utility Pump can be place on the floor or in a pit.
Power Source: The utility pump runs on electricity.
How It Works: Automatic utility pumps have a sensor that sends a signal to a controller to turn the pump on. Manual utility pumps run when they are manually plugged into an electrical outlet. When they are unplugged they no long run.
When Not To Use: Some utility pumps can be submerged in water; others cannot be submerged; therefore it is important to define their intended usage. Utility pumps are often called multipurpose pumps because they can remove standing water off basement floors, draining aquariums, and water beds, boost water pressure, remove condensation and transfer water. The size used depends upon how far the water would be moved and how much horsepower is needed. The location of the discharge must be determined because there are top and side discharges.
Specification Considerations: What will the power source be? How high and far will the water be pumped? How much horse power is desired? Should it be automatic or manual? Will it be submersed in water? What is the application (moving large amount of water, removing condensation, boosting water pressure)? Is there debris in the water?
Location: The Well Pump is placed in a well (shallow or deep).
Power Source: The well pump runs on electricity.
How It Works: A pressure tnak is required because it monitors the need for water by identifying the pressure of the water in the tank. When the pressure goes below the defined value, a pressure switch is activated to turn on the pump. The pump then refills the pressure tank.
When Not To Use: Must know how deep well its, what is the diameter ofthe casing. and how much horse power is needed. A shallow well jet pump can pull water from a maximum of 25' depth-to-water. ... In a deep well jet pump setup, the nozzle & venturi are put into an ejector package or “jet kit” that gets placed down in the well. If you do not have a well casing, you have a shallow well. Some well casings are 2” and require special accessories with a convertible jet well pump. If your well casing is 4” or more in diameter, you can use either a jet well pump or a deep well submersible pump, depending on the depth of your well.
Specification Considerations: What is the depth of the well? What is the diamater of the diameter of the well casing? How much water needs to be drawn at what height and how frequent?
