TW20BB-1 - The Ultimate Whole of House Rural or Town Supply
This whole house system when installed on a Town water supply will need a pressure limiting valve installed before the housings to protect them from too much pressure.
These NSF Approved Alpine Pure System Housings are for those of you that want the best water flow and maximum dirt/chlorine/heavy metals holding capacity available. Manufactured with 1" BSP ports. Package includes 2 X 20" BIG Blue housings, Twin Stainless Steel bracket with SS screws, spanner and a 25mm housing joiner. Suitable for all our 20" X 4 1/4" filter cartridges.
In a rural situation for sediment control we recommend a 50-20 micron Gradient Density followed by a 20-1 micron final cartridge. If Taste or Odor is an issue then the 20-1 micron Gradient Density goes first followed by a Carbon Block 5 or 10 micron depending on your budget.
For Chlorinated town water a 20-1 micron Gradient Density always goes first followed by the 0.5 micron carbon block PB1 for the Ultimate protection or the 5 micron CTO for Chlorine, Taste and Odor removal.
