This Reverse Osmosis System uses a standard Microline manifold with shorter filter housing sumps. Thanks to the internet, we did have an option available to convert your system back to a standard Microline System, and save money on replacement filters. All you needed to do is replace the filter housing sumps with standard Microline filter housings. This would have allowed you to use standard Microline Filters.

We have had a few customers with standard Microline Systems tell us that the company who came out to change filters converted their standard system to accept only the shorter, larger diameter S7125, S7128, and S1448RS RO Membrane. AND the company did this without telling the customer what they had done. The customer realized this after they had ordered standard filters from us and found that they would not fit.
 
We contacted the manufacturer and were told that the only difference between a Microline System that uses Standard Filters and one that uses the S71XX Series filters is the filter housing Sumps. Once you replace the Filter Sumps with Standard Microline Sumps you can use Standard Microline Filters.

To Use Standard Microline Filters, Replace The Filter Housing Sumps With Standard Microline Sumps.

If you need a S7111 filter, Replace The Filter Housing Sump And Order S7011.
If you need a S7125 filter, Replace The Filter Housing Sump And Order S7025.
If you need a S7128 filter, Replace The Filter Housing Sump And Order S7028.
If you need a S1448RS or S1340RS Membrane, Replace The Filter Housing Sump And Order S1229RS.
