Fleck 2510 vs 5600: What Is The Best For You?

Water softeners are a great addition to any house. Especially if you’re concerned about the quality of water in your house. They help remove additional chemicals from your water, giving you a fresh supply. 

Choosing the right water softener is important. A good softener not only provides consistent quality but is also easy to use. For this reason, the products from Fleck are considered to be the best. 

The debate is very common due to their similarities.

Which one should you go for between Fleck 2510 vs 5600? 

When it comes to choosing the right water softener, you need to take a few things into account. These include the size, capacity, ease of use, etc. If you’re looking for complete control over your softener, the 5600 is the way to go! If automation is your choice, we recommend the 2510.

In this article, we’re going to compare between Fleck 2510 and 5600. Let’s begin!

How Do Water Softeners Work? 

Before we get into the comparisons, we need to know how water softeners work. In layman’s terms, water softener is a tool that reduces water hardness. It’s connected to your water supply and it filters out any chemicals. 

So, how is it different from a conventional water purifier? Purifiers are not good at dealing with hard chemicals. So, even after purification, these hard materials remain in your water.

Water softeners have an ion exchange resin that helps them separate the materials from water. 

Afterward, sodium ions are added to the water, making it soft. The hard materials are then taken out of the softener as discharge. It’s important to deal with the discharge carefully since they can be a bit toxic.

While you can discard them, you can use the softener discharge for other tasks as well.

Fleck 2510 Vs 5600: Detailed Comparison 

Comparing two similar products is always hard. Especially when they’re from the same manufacturer. To make our comparisons easier, we’ve divided it into parts. 

Without further ado, let’s get into it!

Resin Capacity 

The resin is the material that keeps the softener together. Once the resin runs out, your softener will stop working. Having a bigger capacity of the resin is always a bonus. 

The 2510 is available in five capacities. The number of grains range from 26,000 to 88,000 gallons. The 5600 has four sizes from 26,000 to 70,000.

If you have a big household or simply prefer longevity. Then, the 2610 might be the way to go for you! 


How much control do you want over your softener? While some people love to control everything manually, others prefer automation. Choosing your water softener based on your choice is useful.

If you prefer automation, the 2510 is the way to go! Once you set the machine up, you can live it that way until it runs out. You won’t have to do anything to make it work. You can make necessary changes whenever you need them.

Also if there are any minor changes, the softener adjusts accordingly. You don’t have to make changes every time. This also creates room for errors. 

On the other hand, the 5600 gives you better controls. You can make changes regularly and you need to set it up manually. This allows you to make changes even at minor intervals. 

Since you can make changes immediately, it’s a lot more efficient. You can set things up accordingly based on your needs. If you’re not well acquainted with the system, it can be challenging.


The speed of the softener is another key aspect. How much water do you need per minute? It should be a key factor in deciding your softeners speed. 

Among Fleck 2610 and 5600, the 2610 is the winner in terms of speed. At it’s best, it can provide up to 25 gallons of water per minute. Compared to it, the 5600 only provides 20 GPM at its best. 

The maximum speeds are only available at their maximum capacity versions. Keep that in mind as well. Also, keep in mind that the softener discharge can kill grass

Additional Features 

There are a few additional features that stand out for either of the 2510 and the 5600. While they aren’t very prominent, they can be a decider in certain cases. Especially, since the softeners have numerous similar features. 

The 2510 has no additional dials or gears. Control is as easy as it gets. To make life easier for you, there’s a built-in stainless steel bypass valve to prevent leakes. The softener also features an outdoor cover for outdoors. 

This makes it ideal if you’re placing your softener outdoors. You need to find a way to deal with the water softener discharge outside.

When it comes to the 5600, it’s pretty feature-packed as well. The built-in capacitor saves the memory up to 48 hours and the display is very efficient. It shows time and remaining water consistency all the time.  

There’s also an adjustable time cycle and safety float system to help you out. So, if features are what you’re looking for, both of them get the job done!

Also, you can use a water purifier with your softener for better drinking water. This is especially if your locality has an abundance of hard materials in water. If you’re planning to get a purifier, check our recommendations-
