Dehumidifier With Pump vs No Pump: Which One to Get?

Dehumidifier With Pump vs No Pump

When it comes to dehumidifiers, the market has the following types of dehumidifiers to offer:

  1. Dehumidifier with a water tank but no drain hose
  2. Dehumidifiers with no pump but drain hose
  3. Dehumidifier with a pump and drain hose

So, today we will discuss dehumidifiers with pump and no pump. After reading this blog, you will understand if a dehumidifier with a pump is suitable for you or not.

So, let’s begin.

Why Do You Need a Dehumidifier With Pump?

If you are anything like me, asking questions about everything is natural. Nowadays, the market is filled with many “best dehumidifiers,” and people use every tactic in the book to increase sales.

So, is a dehumidifier with a pump also a gimmick, or do you need it?

Well, the short answer is, yes, you need a dehumidifier. And the following reason will elaborate why:

Freedom to Drain Water Tank

Do you know how the built-in pump on a dehumidifier works?

Well, the best thing about a dehumidifier with a built-in pump is that it allows you to drain the water tank from anywhere in the house. You can just put the dehumidifier hose in the sink or out the window, and the water tank will empty itself without any further assistance.

Unlike most other dehumidifiers, you do not need to lift it to drain the water when the water tank is complete. In that sense, the built-in pump also saves you from accidental spillage.

Lastly, the built-in pump allows the dehumidifier to pump the water up to 15 feet away. And without this technology, you would be stuck with putting the dehumidifier near the drainage point in your house.

Why do Most Dehumidifiers Not Have a Pump?

After reading the above section of this dehumidifier with pump guide, you know how vital the pump is. This fact ignites the question if dehumidifiers with pumps are so good,

Why do most dehumidifiers lack a built-in pump?

Well, the following two reasons will answer this question:

Gravity Fed Hose

Most of the dehumidifiers without a pump also feature 24-hour continuous drainage. But the drainage technique is slightly different than the dehumidifier with the pump.

The no-pump dehumidifier has a gravity-fed drainage system. In other words, the drain needs to be below the water hose. It helps the dehumidifier to drain the water tank quickly.

So, the dehumidifier with no pump is not entirely inconvenient. They need a little assistance to finish their job. And most users do not mind being a helping hand.

Inexpensive Design

The built-in pump is undoubtedly a nice feature, but it is also expensive. So, if you are on a tight budget, then a dehumidifier with no pump is a great option. Because of their simple design, they do not cost much and are affordable.

Perfect for Small Spaces & Mild Humidity

A dehumidifier with no pump usually has a lower extraction rate and smaller size. This makes them suitable for small spaces or areas with mild humidity. For example, you can use a dehumidifier with no pump in your RV.

Comparison: Dehumidifier With Pump vs No Pump

Now that you know the reasons for buying both dehumidifiers with and without a pump, let’s see the difference between these two products. Following is an in-depth comparison of the dehumidifier with pump vs without pump.

Let’s get started.


Convenience is always a significant factor when it comes to home appliances. Because no matter how much time you have, no one likes to empty the dehumidifier water tank multiple times manually. This process can especially be hectic for those living in an extremely high humid area.

This is where the dehumidifier with the pump comes into play. Unlike the conventional dehumidifiers, the dehumidifier with a pump automatically drains the water tank.


For the above reason, I said that a dehumidifier with a pump is convenient because it features continuous drainage. Well, dehumidifiers without pumps also come with continuous drainage. However, the difference here is versatility.

A dehumidifier with no pump can continuously drain the water tank only if the drainage is lower than its level.

For instance,

If the dehumidifier with no pump is on the floor, you cannot drain it in the sink. However, the dehumidifier with the pump has no issue doing this. You can put the dehumidifier with the built-in pump on a 15-17 feet lower level than the drainage, and it will still drain the water tank.


The dehumidifier with a pump allows the water tank to be emptied at a distant location. In other words, the water tank can be around 15 to 17 feet away from the drainage point.

If the hose is connected, it will empty the water tank without any problem.

Energy Cost

It is common knowledge that a giant machine would use more energy. This is the same concept with the dehumidifier with a pump and no pump. Due to the extra pump feature, the dehumidifier with the pump uses more energy. Hence, it is not suitable for those looking for an energy-efficient alternative.

However, a few dehumidifiers with pumps are also Energy Star Certified. And those devices give you the best of both worlds.

Overall Cost

A dehumidifier with a pump is more expensive to run, but it is also priced higher. The reason behind this is the same. The built-in pump is costly, and it raises the overall cost of the dehumidifier.

What are the Best Dehumidifiers With Pump for Garage

When getting a dehumidifier for the garage, the dehumidifier with a pump is always my first choice.

This is because we need a dehumidifier for garages that can work independently without needing any extra assistance. And this is precisely what a dehumidifier with a built-in pump is.

So, which dehumidifier with a pump is best for your garage? Well, fortunately, I wrote an entire long-form article on this topic. You can check out the Best Garage Dehumidifiers article. It lists the best garage dehumidifiers with continuous drainage and a built-in pump.

What are the Best Dehumidifiers With Pump for RV

The best features for a dehumidifier for RV are slightly different from any other dehumidifier.

For example,

An RV dehumidifier needs to be smaller than conventional dehumidifiers. It also has to be quiet enough not to be an inconvenience.

Similarly, a built-in pump feature is also highly sought after. Because RVs usually lack space and drainage systems. And the built-in pump offers you the freedom to put the dehumidifier wherever you want.

If you are looking for a dehumidifier with a pump for RV, you are at the right place. Check out this Best RV Dehumidifiers review I wrote a while ago. This article contains all of my favorite dehumidifiers for RV.

How To Do When Dehumidifier Pump Not Working?

Here are a few reasons why a dehumidifier with a pump might stop working. If that is happening with you, there is no need to worry. The following are the reasons why a pump stops working. And I have also mentioned the solution to each problem.

Incorrect Installation

If you buy a dehumidifier with a built-in pump, then it is not a problem for you.

However, if you purchased the pump separately, incorrect installation can cause the pump not to work correctly.

In other words, some pumps work horizontally. Meanwhile, others need to be vertical to pump the water properly. If you notice your pump is not working, you can use the following steps to solve the issue.

  1. First, ensure the hose is connected correctly to the dehumidifier.
  2. Now click the pump button to turn on the control panel to turn it on.
  3. If the pump is installed correctly, the pump indicator light will go on.

However, if the light does not turn on, the pump is not installed correctly. In that case, reread the instruction manual and install it accordingly.

Pump is Defective

Another important reason your dehumidifier pump is not working could be a lack of voltage.

You can check it by uninstalling the pump and connecting it with a voltage tester. If the voltage does not come out from the other side, the pump is defective, and you need a new unit.

Conclusion: Dehumidifier With a Pump VS. Without Pump

After reading this blog, I hope you can select between a dehumidifier with a pump vs without pump. To conclude it all, a dehumidifier with a pump is slightly more expensive to run because of the built-in pump. However, the advantage of a dehumidifier with a pump is that it can empty the water tank to a distant drainage point. For instance, a 30-pint dehumidifier is suitable for basements.

On the other hand, a dehumidifier without a pump is more affordable. However, it can only empty the tank if the drainage point is lower than the dehumidifier.

Both of these dehumidifiers come with their pros and cons. So, choose the one which is suitable for your space.
