Waterboss 700 Water Softener Review

In this post, we review the WaterBoss 700, a 22,000 grain capacity whole-house water softener.

Do you ever take a drink of water and want to shout yech? Or maybe you’ve noticed your soap doesn’t foam like it should and there are a lot of stains on your sinks? 

These are signs of hard water, containing too much calcium and magnesium.

Today, we will explain why this softener from WaterBoss may be the perfect softener to fix  those problems and provide you soft water. We’ll also cover some reasons you might want to consider an alternative.

WaterBoss 700 Reviewed


The WaterBoss 700 is a 22,000 grain water softener with an eight gallon per minute flow rate. That’s enough soft water for four people. While it’s not a high grain capacity, it is enough for many small homes.

This softener uses metered regeneration, meaning it will only initiate a regeneration cycle when it has used up its full softening capacity. That makes it efficient, reducing the amount of salt wasted and lowering its water usage. 

A regeneration cycle for the WaterBoss 700 softener is less than 20 minutes. That’s less than the regeneration cycle time of many others. It’s so quick you probably won’t even notice when it happens.

The WaterBoss 700 is a single tank softener, so it takes very little space in your home. It’s perfect for a small basement area, using about the same amount of floor space as a water heater.

Whether you connect to the city water supply or you’re connected to a well, this softener will work great for you. It can handle water with a hardness level of up to 70 gpg. That’s harder than most people have, with only a small fraction having water that is any harder.

You’ll also get clear water iron reduction with the WaterBoss 700 water softener system. It will remove up to 10 ppm of clear water iron. This can improve the taste of your water, and it’ll result in fewer red and brown stains in sinks and around drains.

The WaterBoss 700 22,000 grain water softener removes calcium and magnesium, which are the minerals that cause hard water. This will prevent damaging buildup in your pipes, saving you money.

This system has a built-in sediment filter. It can filter out dirt and sediment down to 20 microns. And you won’t have to replace this sediment filter like you have to do with other filters because it is self-cleaning. 

But, as with softeners from any manufacturer, there are some downsides to this unit for you to consider before you part with any money. 

First off, some customers have left reviews where they note that it leaks. While this can come from mistakes while installing, this water softener is one of the easiest to install softeners you can get.

Other customers note in their reviews that they can taste too much salt in the water when they use the WaterBoss 700 22,000 grain unit. You shouldn’t notice the salt in your drinking water when using a water softener.

Some customers say in their reviews that they had trouble getting WaterBoss to stand behind their warranty when there was a problem.

What Comes With The WaterBoss?

The WaterBoss comes with pretty much everything you need to install and operate it. You get the combination resin and brine cabinet, plus all of the following:

  • Bypass valve (preinstalled)
  • 22,000 grain resin
  • Self cleaning sediment filter
  • Water test strip
  • Manual
  • Drain line
  • Electrical transformer
  • Installation kit
  • Water test strips
  • DVD showing the installation process

Installing the WaterBoss

The WaterBoss 700 22,000 grain water softener is one of the easiest softeners to install. It comes with an installation kit that includes a DVD showing the whole process, as well as a manual with in-depth instructions so almost anyone can do it themselves. This can save a lot of money over hiring a plumber.


Here are the basic steps to follow when installing your WaterBoss softener:

  1. Place your Waterboss in place, making sure to leave a few inches of room between the appliance and the wall. Choose a location near a drain and electrical outlet. If you have a stand-alone filter, place the softener after it in the water line. See the diagram from the WaterBoss owner’s manual below.
  1. Turn off your home water supply.
  2. Open faucets in your home to depressurize and drain.
  3. Lift the cover off the softener.
  4. Install the connections from your water supply. The water flow should follow the arrow on the valve. This may require splicing into your existing plumbing. Be sure to run a copper wire across where you spliced in so that your plumbing retains proper grounding.
  5. Connect the overflow elbow to the side of your WaterBoss 700 cabinet.
  6. Run half-inch tubing from the elbow to a nearby drain. This tubing is not included in your kit.
  7. Attach the included drain line to the drain end cap, then run the other end of the drain line to a nearby drain.
  8. Turn the bypass valve to the “bypass” position.
  9. Turn on the water to your home.
  10. Open a nearby cold faucet to flush installation debris.
  11. Set the valve to “service”.
  12. Close all water faucets.
  13. Check for leaks in the water connections and around the WaterBoss water softener.
  14. Connect the transformer to the back of your system and into a power outlet.
  15. Program the system, as explained in the manual.
  16. Add two gallons of water to the brine cabinet.
  17. Press the regenerate button to advance to the “brine refill” position.
  18. Fill the tank with salt.
    20 Run a water faucet for 20 minutes.
  19. Put the cover back onto your system.

Maintaining the WaterBoss 700 22,000 Grain Water Softener

The WaterBoss 700 is designed for easy maintenance. Most of the time you’ll only need to add salt. 

A salt bridge can occur in your salt tank. To fix this, simply push a broom handle through the salt to break it up. Be careful not to damage your water softener. 

If you get an error code on your system, you can often fix it by simply resetting your softener. You reset the WaterBoss 700 by disconnecting it from power for at least 30 seconds. When you plug it back in, it should reset and work as normal in most cases.

WaterBoss 700 vs. Competition

The WaterBoss 700 22,000 grain softener stacks up well to the competition. Let’s compare it to two of the top-rated systems, the Quality Water SoftPro Elite for Well Water and the Springwell Salt Water Softener System.

WaterBoss 700 Advantages

  • You’ll save a lot of money by buying the WaterBoss, which is about half the cost of the other two water softeners.
  • The WaterBoss 700 is quieter than the competition.
  • The WaterBoss water softener will remove up to 10 ppm of clear water iron, while the others will only remove up to 3 ppm.
  • The WaterBoss has a Built-in filter, which removes dirt and sediment.

WaterBoss 700 Disadvantages

  • The warranty length of the WaterBoss is only 3 years parts, 10 years on the tank. Both other systems have a lifetime warranty.
  • The Springwell water softener is a little larger and can handle up to six people vs. four for the WaterBoss.
  • The WaterBoss flows eight gallons per minute, which is similar to the seven gallons per minute of the SoftPro Elite, but the Springwell beats them both with its eleven gallons per minute flow rate.

In Conclusion

The WaterBoss 700 22,000 grain water softener is perfect for a small home, especially if you’re looking for a low-cost system. If you like what you see but you need a larger softening system then you may like the 900, which you can see in this brochure.

While this is a very good water softener, you should compare it to the softeners on our best water softeners list to make sure it is the right one for you before you make a purchase. You may also want to check our list of best softeners for well water.
