Exposed Thermostatic Shower System 15-Year Maintenance Service Pack

Your premium thermostatic shower system contains a sophisticated thermostatic cartridge and components that over time experience wear and tear, corrosion, and build up of mineral deposits which impair their proper functioning.

To ensure continued safe and enjoyable use of your thermostatic shower system, we recommend servicing it about every 15 years. You should replace the thermostatic cartridge, volume control cartridge, both check valves, and both neoprene washers.

We have assembled these parts into one pack for the 1/2" exposed thermostatic shower system and another pack for the 3/4" exposed thermostatic shower system.

Clean, Healthy Water Throughout Your House with No Destructive Hard Water Scale

Superior Whole House Water Filtration System

Water is essential for your life and lifestyle. You use it every day for drinking, cooking, and washing yourself. You also use it daily for washing your dishes and clothes, and many other practical uses.

Household water can contain hazardous heavy metals, harmful chemicals, pathogenic microorganisms, and minerals that form limescale which destroys your clothes, faucets and shower systems, plumbing fixtures, and home appliances.

Utilizing the state-of-the-art ScaleStop Template Assisted Crystallization technology, our water filtration systems:

  • Produce pure, clean water for drinking, cooking, washing, and bathing
  • Remove 99.9%+ of all soluble lead, mercury, copper, and other dissolved hazardous metals
  • Removes chlorine while retaining beneficial minerals
  • Prevents hard water lime scale which mars clothes, glassware, silverware, dishes, and shower surfaces, and slowly destroying faucets, faucet cartridges, shower systems, dishwashers, washing machines, hot water heaters, and plumbing piping

Researchers at Arizona State University found that ScaleStop Template Assisted Crystallization removed 99% of hard water scale.

  • No salts
  • No chemicals
  • No electricity
  • No waste water
