Note: Please make sure you have selected the correct option before checkout.

Our Whole House water filtration systems are designed to deliver safer, cleaner, water to every faucet and showerhead into the whole house without reducing down water pressure. By using oversized filter cartridges and housings this system maintains the strongest water pressure possible. In addition, these larger housings and filters require less frequent services, which saves you time, money, and effort.

Vertical Hydraulic Gauge

Having a pressure gauge is helpful in monitoring your incoming water pressure, internal unit pressure & when to replace the filters. It's best to replace the filters when you see changes in reading start, an increasing pressure drop is a good indication that the cartridges are starting to clog with particulate or the filter's media is exhausted as the water inside the system can’t pass through the filters normally.

Use the gauges on the system to check the following:

  • The first pressure gauge to read your feed water pressure (city water, well, or cottage pump water pressure) and the outgoing pressure from the first stage.
  • The second gauge to read the second filter outgoing pressure.
  • The third gauge to read unit internal pressure.

appearance is good seems to work fine but carbon from 2nd filter covered outside of 3rd making it black. No instructions on what order to put in filters. 2 out of 3 red pressure relief buttons leaked for a day, fixed themselves. As they say in the instructions leave lots of room for the filter wrench as it has to slide up near the top to work.
