Choose an easily accessible frost-free location near the main water supply for your home.

You want to ensure that it’s easy to drain and clean the Conditioner every 3 to 6 months.

Remember, you are treating and filtering the entire incoming water supply for the whole house.

The Silkwater Technologies Water Filter & Descaler units are relatively easy to install, but if you are not experienced or confident enough with DIY projects, you should get a local plumber for professional help.


How to install the Water Conditioner unit.

  • Turn off the main water supply and drain the system.
  • Choose the new location for the conditioner unit and mark it. If located outside the house, choose a location that is safe from frost and extreme weather. Keep in mind you’ll have to drain and service the conditioner occasionally so choose a location you can reach comfortably.
  • Cut the pipe using a pipe cutter.
  • Optional but recommended – install a shutoff valve for water entering the filter and one for water leaving the filter
  • Install the compression nut and plastic or brass fittings according to the manufacturer’s instructions. It’s recommended to use pipe thread tape on the fittings for better sealing.
  • Install the conditioner with the “in” and “out” ports facing the right directions.
  • Turn on the main water supply and check for leaks.
  • The installation is complete. Every time you need to drain and clean the conditioner, turn the valve on the bottom of the filter unit.
