Detailed Description:

3-Stage 20"x 4.5" Whole House Big Blue Water Filtration System  1" NPT Ports

Get clean and clear water for your whole house by removing dirt, discoloration, odors, and bad taste with our 3-stage Whole House system, perfect for homes, cottages, and offices.

1" Ports (Inlet/Outlet Sizes): Flow Setup Direction is Right to Left (Right Inlet - Left Outlet)

The clear housing is on the Inlet Side, allowing you to inspect the sediment filter.

Our Whole House water filtration systems are designed to deliver safer, cleaner, water to every faucet and shower head into the whole house without reducing 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.

Pre-loaded Filter Cartridges:

  • 1st Stage: 10 Micron Pleated Sediment Filter 104117
  • 2nd Stage: 5 Micron Polypropylene Sediment Filter 104112
  • 3rd Stage: (GAC) Granulated Activated Carbon Filter 104113

Vertical Hydraulic Gauge

Having a pressure gauge helps monitor 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.

Item is installed and working well. It has definitely improved the quality of the city water and has not affected the water pressure. Unit required some minor adjustments after installation. Customer service was helpful to resolve the issues.

Excellent Results
The System is working fine - water quality here is known to be poor and the Three Stage Big Blue system takes care of that great. Water tastes sweet and is clear as a bell.

Excellent Solution to Hard Water
My neighbor installed the Lake, Well & Cottage Whole House Water Filtration System three years ago and was very happy with it. In March 2020 I purchased the same system but had to wait to install until the COVID lock down ended last month. Suffice to say the change from our very hard water to filtered was and is like the difference between night and day. The Big Blue Whole House system is 5 star. I will be recommending it to the entire neighborhood of thirty neighbors.
