WAYNE CDU800 Submersible Cast Iron and Steel Sump Pump

The WAYNE CDU800 1/2 HP Submersible Cast Iron and Steel Sump Pump with Integrated Vertical Float Switch is a complete system. The model is available as an individual pump, a pump, and battery together, with a separate battery purchasable individually too. For homeowners (and professional plumbers) who want to purchase complete systems or easily replace batteries that have failed, the availability of different purchasing options with CDU800 is helpful.The system is ideal as a backup sump pump for occasions when the power cuts out, and only a backup battery-powered sump pump will keep the basement and other areas of the home from flooding. For homeowners looking for a secondary sump pump to protect against the first one failing in a rain storm, the Wayne CDU800 model certainly offers some food for thought.wayne cdu800 sump pump

The motor is a ½ horsepower motor that is stronger than most sump pumps in this category. It is fully submersible and comes with a vertically-positioned switch. The casing is made of cast iron for greater protection from outside elements, and the base is also cast iron rather than plastic. The impeller is constructed from polycarbonate that’s been strengthened. The steel fasteners are made of stainless steel and have been treated to protect from corrosion.The CDU800 is intended for installation inside a sump basin that is at least 11-inches in diameter to accommodate the unit. It is capable of pumping out 4,200 gallons of water per minute which drops depending on the upwards direction of the water via a one ½-inch discharge diameter. Suction is powerful and intended to clear debris efficiently to avoid the frequency of clogging. There is a mechanical seal that’s ceramic for reliable performance.

The engine already comes with oil and avoids overheating through a thermal system. The ball bearings remain lubricated; the motor windings avoid damage due to the thermal protection, and the grounded 3-prong electrical plug runs through an 8-foot power cord to access power outlets outside the sump basin.The switch uses two poles to ensure that should one switch get stuck in the ON position, the second pole will not. The inclusion of this feature avoids the prospect of the engine overheating and blowing out due to a switch that became stuck.There is a 3-year limited warranty with this product which is quite generous.
