NOTE:  If you are changing membranes, it is always a good practice to change the drain line flow restrictor on the reverse osmosis system.  It can become plugged with years of usage (which mean that you don't have enough flow to drain to properly flush the impurities off the membranes' surface, causing early membrane failure), or if you are installing a larger or smaller membrane, the flow restrictor needs to be changed.   This 25 GPD Membrane utilizes a drain line flow restrictor that is capable of approximately 100 GPD of 260 ml to drain.

  • I have a rainsoft reverse osmosis system and wonder if this membrane would work on my system as well uf 50 system.

    Most Rainsoft membranes are proprietary and do not interchange with others.

  • Will this filter replace a GE FX12M, and do I need to replace the flow restrictor as well?

    Yes and Yes

  • I have a "Pentair Water" Model TLC-36. Will the US Water Residential Membrane 25 GPD be a direct exchange?
  • Hi, I have a WRO-4500 system. it requires WROM-25T Reverce Osmosis membrane (which is 9-7/8" in length), you are offering a US Water Residential Membrane 25 GPD (Sku: 255-USWM-1812-025) which is 11.75" in Length. Is it going to work?
