The Wayne CDU790 has many features that make it a great choice for a sump pump.
Build Quality and Design
Wayne invests a lot in creating well-designed sump pumps, which is evident in the Wayne CDU790 Submersible Cast Iron and Steel Sump Pump. The product comes with a light and compact design that allows the pump to be used in sumps 11″ in diameter.
A highly noted point about this design is the discharge and float proximity to the motor casing, without causing either part to suffer reduced functionality. Furthermore, the structure has a small cast iron base with short legs, which ensures the stability of the product regardless of the flatness of the sump bottom.
Without premium build quality, a good design is meaningless. So we find Wayne providing high-quality cast iron housing for the product to ensure it against the twin dangers of corrosion and impact of large debris. In addition, corrosion-resistant paint has been applied over all external parts to provide added defense against decay.
The only exception is the float (which is not made of metal) and the stainless steel handle and switch guard. Some users argued that this made them more susceptible to corrosion. Still, long-term users countered them, arguing that despite extensive exposure to water, these parts never did show any signs of corrosion.
Major External Parts (Discharge, Power Cable, and Handle)
The discharge is a standard 1-1/2″ NPT cast iron component capable of passing small spherical solid bodies along with the water, thus ensuring no buildup of these tiny particles at the bottom of the pump.
On the other hand, the 1-1/2″ NPT size ensures that there is never any incompatibility issue as far as the PVC piping is concerned.
It is fitted with a top suction strainer which allows the product to filter debris easily and therefore precludes the possibility of the pump being clogged up due to accumulation of debris.
The power cable, on the other hand, is of decent length, and when considered and it is fully submersible, it appears to be one of the better power cables in the industry today.
As we noted above, there is a convenient stainless steel handle at the top of the sump pump, which is shaped to ensure easy compatibility with most hand sizes.
However, a few users with extensive hands noted that they could not insert all of their fingers into the handle space and hence had difficulty raising and lowering the product.
Motor and Sealing
True to Wayne’s reputation for providing robust and dependable motors, the product comes with a 1/3HP motor, which is the maximum one can expect in this price range. Coming to the equally crucial question of pumping output, we find the product capable of pumping an incredible 3450 gallons per hour at 5′ head.
Further, as our sump pump reviews have shown, a product that consistently achieves a maximum head of 20′ is an excellent value for money proposition. This Wayne product thankfully reaches this mark and maintains it successfully for the duration of pumping operations, thereby staking claim to a position in the category of suitable sump pumps.
Longevity is a vital part of the value for money calculation, and motor sealing is a crucial part of the longevity test. The Wayne CDU 790 passes this test admirably courtesy of the ceramic seal separating the motor from the housing and disallows water from going into the vital internal components and ruining them.
Impeller and Switch
The Wayne CDU790 Sump Pump comes with a standard cast iron impeller, which not only ensures adequate support to the top suction strainer mechanism of the discharge but also protects itself and the base from damage due to collision of heavy debris with the underside of the pump.
The switch utilizes the well-reputed PVC float system that consists of the large and stable float, the steel suspension rod, and the shaft which connects to the switch. As the water level rises, the float is dislocated, and pressure is applied to the shaft through the float suspension.
This triggers the susceptible bipolar switch, causing the motor to start. Though the float is extremely durable, the precise arrangement of the system necessitates additional safeguards, which come in the form of a large and hardy stainless steel switch guard.
Is It Worth Purchasing?
Considering all of the above factors, it is not surprising that the Wayne CDU790 enjoys such a stellar reputation in the industry. This is a product that has been designed and built to last and which provides terrific value for money in terms of both performance as well as longevity.
It ticks all the boxes in terms of the features one looks for in a sump pump and is indeed a worthy candidate for being crowned the best sump pump in its class. The Wayne CDU 790 is one of the most popular pumps on the market today, and it’s easy to see why.
