About the Wayne CDU800
The CDU800 is one of the most popular pumps in Waynes line of water pumps and a good choice for homeowners looking for a pump with little to no maintenance without sacrificing power.
Sump Pump Features
We checked out the CDU800 to find out if it is a good pick for your basement or crawl space. The pump itself is well made and weighs in at a solid 17.8 pounds. Most of the body is made of cast iron, stainless steel and ceramic seals which is better and less likely to crack than ABS plastic pumps. It is a large pump so it needs to be in a sump pit 11″ in diameter or larger or it won’t have room to sit at the bottom.
The pump is activated by a vertical two pole float switch which rises with the water level and activates the water pump. One of our favorite features is the backup float guard to prevent sticky switches.
- Fits 11″ and larger pits
- Max 5100 gallons of water per hour
- Installs in 15 minutes
- Anti airlock design
- Watch for rust on exterior metal parts
The CDU800 is a top suction, 1/2 HP cast iron pump that can drain up to 5100 gallons of water per hour at 0′ head height – or 2040 gallons at a 20′ head height which means the pump has quite a bit of power. The motor is activated by a two pole float switch at 4″ or 9″ as the water rises in the basin.
The motor in the CDU800 is a 1/2 HP motor that packs quite a punch when pushing water though the 1 1/2″ NPT lines. The inside features a reinforced poly carbonate impeller to push the water. The float guard prevents overheating and dry running which are two of the most common reasons pump burn out.
This pump has a two pole float switch that is backed up by a float guard. When water builds up in the sump pit the switch rises and activates the pump and starts the motor. This pump has built in back up mechanisms to prevent sticky floats and over heating – two of the most common problems of dead sump pumps.
CDU800 vs CDU980E
The CDU800 and CDU980E are very similar, the main difference is that the 800 has a 1/2 HP motor while the 980E has a 3/4 HP motor.
Installation and Troubleshooting
This pump can be installed in about 15 to 20 minutes. The pump pit needs to be at least 11″ in diameter in order to fit the pump so make sure to measure before ordering. The pump comes with a 3 year warranty in case anything goes wrong which is unlikely due to the high cast iron build quality.
