Who Is This Product For?

Like any other electronic product, it can’t suffice everybody’s needs. That’s a reality. Every product is designed for a certain group of customers.

Before buying anything, it is crucial to know for whom this product is made. It will save you from making the wrong decision.

Here is a list. If you can relate to any of these circumstances, it is time to install this Wayne CDU800 sump pump.

  • Your old sump pump makes loud noises and you totally dislike it.
  • You live in a house with a low to average water level.
  • Your old 1/3 HP or ¼ HP can’t handle the amount of water running into your sump pit. (You need to upgrade to this ½ HP sump pump).
  • You have respiratory diseases like Asthma or other allergies. Moisture in the house can trigger such diseases.
  • You are planning to sell your house. ( this sump pump can add value to your property)
  • Your sump pit needs more powerful vertical lifts; like 3150 GPH at 10 feet.

Problems You Might Face

Being proactive is better than being reactive. Every product comes with its flaws. It is wise to know how you can defeat these problems instead of ignoring them altogether.

Let’s take a look at the troubles other customers have faced.

Float Switch Failure

If you go through the customer reviews, you will find most of them complain about float switch failure. Though Wayne has designed a reliable switch guard, it can still fail.

Improper installation is the main factor that works here. Homeowners sometimes plug it into the sump pit on their own. It can lead to a wrongly positioned pump base.

It then causes the float to fall into a trap between the wall and the pump. As a result, it can no longer detect the water level precisely. And we all know what happens when the float switch fails.

You can solve this problem by asking for help from a professional. Reading the manual thoroughly will also help.

It Shuts Down During Power Cut

This CDU800 doesn’t come with battery backup. It uses the main electricity line in your home for energy.

It is not uncommon to experience power cut during a storm. That means your sump pump will stop working when the power goes off. That’s not a good sign if your house is facing a heavy rainstorm.

You can solve this problem by installing a backup sump pump with long-lasting batteries. This backup system will kick on if your main sump pump collapses. Besides you can install a generator in the basement too.

Wayne CDU800 Review: Features And Benefits

Let’s dig deeper into our Wayne cdu800 sump pump review and find out what it has to offer.

Cast Iron Body And Stainless Steel Fasteners

If you have researched a bit about sump pumps, you already know what cast iron is. It is the best sump pump material out there.

It is corrosion resistant and can handle thermal shocks better. It means, it can handle sudden temperature change, like pouring hot oil inside the pump or spraying ice-cold water on a hot pump.

Besides, cast iron dissipates the heat of the pump into the fluid. Thus, it plays a role in keeping the pump cooler.

And stainless steel has 10% or more chromium in its structure. It can stay in shape at higher temperatures too. As a result, it doesn’t let water get into the pump and damage it.

Thermally Protected Motor

Sump pumps have to deal with overheating issues all the time. Basically, an impeller receives the electric power and turns it into rotating energy. This rotating energy then transforms into kinetic energy and moves the water.

Debris or pebble may get stuck in the impeller and stop the rotation. But the pump is still running. It causes the electric power to turn into heat.

Now, this CDU800 model is thermally protected. It means it has a sensor that can detect heat rise up, and halt the operation. When the pump is cooler again, you have to press the reset button.

Polycarbonate Impeller

Polycarbonate has carbonate groups in its structure. It is tougher and more durable. It is closer to impossible to break.

Polycarbonate impeller can take more abuse of flying debris without any wear and tear.

Besides, polycarbonate impellers have thermal insulation properties. As a result, they don’t melt and deform while having contact with hot water.

Efficient ½ HP Motor

It offers you a ½ HP motor that can vertically lift 3150 GPH at 10 feet. It is 35-40% more powerful than the 1/3HP ones. It is sufficient height for an average household.

Also, the pump is oil-filled. Oil-filled pumps are always more preferable if you need a quieter operation. Oil dissipates heat equally throughout the fluid and removes hot spots. And your bearings and fittings are always lubricated.

Pretty convenient, right!

Additional Features:

  • It comes with a carrying handle. You can easily lift it without damaging the cord.
  • It comes with a watertight seal. The seal adds to its quietness. Besides, the seal also keeps it cleaner.
  • It is a compact submersible pump. The plumbing is already done. You just need to plug it in and there you go.
