When we found that many of our customers needed to have the higher power of the ScaleWatcher 5 star but had no need to mount it outdoors, we created the ScaleWatcher 4 star which has the same power as the 5 star but cannot be mounted outdoors. Priced at $699, the ScaleWatcher 4 star model compares with the EasyWater 2200 ($1200). With the included ten year extended warranty it is a great value and quickly becoming one of our best-selling models.
It has the power converter inside the unit which obviates the complications of having a separate converter as found in other models.

Product Features

  • Removes scale build up in hot water heaters, saving energy costs.
  • Gives soft water feel without salt or cartridges to replace.
  • Works on all types of pipes (PVC, Pex, Copper, galvanized, flex pipe, rubber hose, etc.).
  • 1 year Satisfaction Guarantee, 10 year product warranty.
  • Free Shipping.

ENGINEER'S CHOICE: The 4 star is the recommended model by the experts for power and durability. No external power converter means less potential failures. (click here to see the 3 star with the power converter)
