What distinguishes the model 950 from other WaterBoss softeners is the fact that it was designed for city water only. In other words, the 22,100-grain capacity system cannot handle iron content.

In return, apart from reducing hardness, it also eliminates chlorine taste and odor (maximum amount of dissolved chlorine = 3 ppm) with the help of a mixed media bed that acts as a built-in and self-cleaning charcoal pre-filter.

As you can see, the WaterBoss 950 also is a drinking water filter.

WaterBoss 950 Water Softener and Filter – Key Features

As far as the softening is concerned, the WaterBoss 950 can treat water up to 35 grains of hardness per gallon.

What is the ideal household size for this unit?

The 8 gpm flow rate is sufficient for up to 4 residents living under the same roof.

Anything else worth mentioning? Absolutely!

The whole house softener/filter is made in the USA and comes with a 3-year limited warranty on mechanical and electronic parts and 10 years on the resin tank and outer cabinet.

Minimum required and maximum allowed pressure: Between 20 and 120 psi.

On a side note: WaterBoss advices against the use of rock salt for optimum system performance. You should use clean pellet, solar or cube-type salt instead. Also, your water’s pH-level should be 7 or above. And lastly, the brine tank should always be at least 1/3 filled with salt.

WaterBoss 950 Pros

Like all WaterBoss softeners, the 950 was designed to use less water than any other retail water softener. And indeed, if the system works as intended, the amount of salt it uses is incredibly low.

This can be achieved because it applies demand initiated regeneration and only recharges if and when necessary. This lowers salt and water consumption which benefits the environment and is easy on your wallet.

Above that, the softener is very quiet during regeneration.

Last but not least, we like the NSF Standard 44 certification for barium and radium 226/228 removal, which is another step towards clean H2O safe for drinking.

Installation + Startup Instructions

There already is a built-in bypass valve, so you don’t have to worry about that when installing the WaterBoss 950.

What’s more, the single-tank design is nice to look at and provides for compactness. Thus the unit won’t take up as much space in your garage or basement as many other softeners would.

Will you be able to install this system DIY-style? Probably – unless you are really not handy around the house. In that case, it might be a better idea to call a professional plumber to do the install for you.

If you are interested, this is a general outline of the process:

If a softener is not equipped with a bypass valve, we recommend you provide for one for ease of maintenance. Also, make sure to comply with local plumbing codes.

1. Finding the Right Place

The WaterBoss 950 requires a power outlet and a drain to be nearby.

Always choose a location before your water heater and close to where the main water line enters your home. This way all the water will get softened.

And make sure to choose a spot where it does not freeze.

2. Setup

  1. Shut off your water heater and turn off its water supply.
  2. Close the main supply valve.
  3. Open any hot and cold water taps to drain all remaining water and depressurize your plumbing system.
  4. In order to connect the water lines, lift and remove the cabinet cover.
  5. Install the Qest connection fittings (included). Attention: Qest fittings do not require the use of Teflon tape or plumber’s putty.
  6. Check the arrows on the ports to ensure correct flow direction.
  7. Attach the water lines to the appliance. Be careful to not over-tighten the connections on the plastic threads.
  8. Attach the overflow elbow in down position and connect 1/2″ tubing (not included) between the overflow fitting and a suitable drain.
  9. Connect the drain line (1/2″) to the drain end cap.
  10. Route the drain line to an appropriate waste receptor. Maintain an air gap.
  11. Next, place the appliance in the Bypass position and turn on the main water supply.
  12. Open the nearest cold water faucet. Let the system flush.
  13. Place the softener in Service.
  14. Close all faucets.
  15. Check all lines and connections for leaks.
  16. Plug the softener into a power outlet.
  17. Program the system using the LCD display (more below).
  18. Add 2 gallons of water into the brine tank.
  19. Initiate a manual regeneration cycle. Allow the appliance to draw water out of the brine cabinet until the air check/draw tube sets (takes about 8–10 minutes).
  20. Press the Regenerate button. Let the tank fill with water.
  21. Fill the brine tank with salt.
  22. Turn on the electricity and water supply to the water heater.
  23. Open a cold water tap and allow the appliance to flush for 20 minutes (approx. 76 gallons).
  24. Replace the cabinet cover.

Programming, Settings & Maintenance

What do you have to do in terms of programming and maintaining the 950?

First of all, configuring the digital control head doesn’t take more than 5 minutes if you follow the manual.

You have to set your water hardness level, the current time of the day, how often you want the system to regenerate, etc. – and that’s about it.

In terms of maintenance, remember to fill up the salt reservoir and make sure that the brine tank + air check is free from sediment.

If you want you can use resin cleaner on a monthly basis.

WaterBoss 950 Cons

These are some of the issues that customers who bought the WaterBoss 950 have struggled with:

  1. Missing/broken parts being shipped.
  2. Complete system failure that causes the softener to regenerate continuously. As a result, it fills the septic tank of customers living in rural areas and floods their drainfields.
  3. Leaking resin bins.
  4. Dead circuit-boards.

On top of that, it seems like the WaterBoss support can’t be bothered. The people answering the calls are barely polite and not willing to help you out in most cases.

WaterBoss 950 Review: Our Verdict

While some users say that if you live in the city, the WaterBoss 950 water softener is the one for you, you should carefully read some of the numerous 1-star ratings to get the full picture.

Chances are that you will not be willing to play Russian roulette and risk having to purchase expensive replacements pieces for your newly acquired softener that broke down all of a sudden.

Bottom line: We cannot recommend this product with good conscious and would advise you to opt for one of the many competing systems on the market.
