Strongest Features

The Wayne CDU800 comes with a lot of features for a sump pump.

Build Quality and Design

As mentioned above, Wayne pumps generally have a standard design comprising a rather thick motor housing, a well-molded discharge, and the switch assembly. Together, these ensure that the product is compact and contains no protruding parts that may hinder the flow of water or get damaged by solid particles in the sump.

The Wayne CDU800 1/2 HP Cast Iron Submersible Sump Pump follows this tried and tested design, except that unlike many similarly priced sump pumps (of both Wayne and other companies), it uses cast iron instead of steel. As is well known, cast iron is more sturdy and capable of handling extreme water pressure during storms, etc.

Furthermore, there is a layer of corrosion-resistant coating, which ensures that the housing does not rust. If that weren’t enough, the base of the pump is also made of cast iron, thus avoiding the longevity problems associated with materials like plastic.

Major External Parts (Discharge, Power Cord, and Handle)

The discharge of the Wayne CDU800 is made of high-quality cast iron, which ensures this vital part against damage due to impact from heavy pebbles, etc. Further, it is so designed that it efficiently assists the motor in removing the maximum amount of water without getting clogged with debris.

The fact that the discharge has a 1-1/2″ NPT diameter ensures that most standard pipes of this diameter can function with this sump pump, thereby saving one the trouble of using valves, etc, to reduce the pipe diameter.

The power cord is insulated and submersible, allowing the user to install the sump pump without having to worry about electrical shocks, etc. Furthermore, the power cord is of decent length, which precludes the necessity of multiple modifications to the house’s electrical wiring before the pump can be used efficiently.

Wayne has provided a stainless steel handle for the pump, which is fixed and cannot be bent as per convenience. Unfortunately, this, and the fact that it is rather small for a person with large hands, makes the handle one of the rare shortcomings of this sump pump.

Motor and Sealing

The heart of any sump pump is its motor, and thankfully, the Wayne CDU800 comes with a powerful 1/2 HP motor capable of working for long hours without suffering any decline in productivity. It can achieve a consistent output of 5100 gallons per hour.

Complementing this excellent motor is the sealing. Wayne has used a superior ceramic seal that allows neither water to flow into the motor nor oil to flow out of it. Coupled with superior quality, well-oiled ball bearings, this device is one of the best sump pumps in terms of motor and sealing quality.

Impeller and Switch Assembly

Wayne knows the importance of using an impeller that can run efficiently even when assaulted by pebbles and other solid particles swirling around with the water in the sump. Cast iron has proved to be the best solution in this situation; hence, we find that the Wayne CDU800 has been provided with a high-quality cast iron impeller. Even better, the impeller’s design allows it to move water rapidly so that the discharge can efficiently transfer it into the outlet pipes even during the rainy season when flooding is a real possibility.

The switch assembly comprises a thick but highly reliable PVC float connected via a steel arm to the switch. When the water rises, the float is pushed upwards, applying pressure on the arm and triggering the switch. The switch itself is bipolar with a provision for auto-shutdown should there be great fluctuation of power supply and/or extreme heating of the motor. This ensures that the switch doubles up as a safety mechanism that ensures the security of both the sump pump and the house’s wiring.

The CDU800 is protected by a stainless steel switch guard, which extends to a distance sufficient to protect the large float. Some users complained that the steel could, on occasion, be dented if the pump collided with the sides of the sump, but they added that despite this denting, the guard continued to serve its function of protecting the switch well.

Is It Worth Purchasing?

If you are looking for a high-quality, durable, and feature-rich sump pump that doesn’t break the bank, then the Wayne CDU800 is perfect. It comes with a powerful motor, superior sealing, an excellent impeller, and a reliable switch assembly, making it one of the best sump pumps on the market today.

Even better, it is quite easy to install and comes with a three-year warranty from Wayne, which shows how confident the company is about the quality of its product.

So, if you are in the market for a new sump pump, give the Wayne CDU800 a try – you definitely won’t be disappointed!
