Ultima uses standard RO membranes and newer systems may use the Pentair GRO Encapsulated membranes.
The newer Pentair Encapsulated Membranes are easily indentifiable and are listed below.
To determine which standard RO Membrane is in your system, locate the drain flow restrictor. It is on the drain line from the membrane housing. It's about 2" long and 1/2" in diameter and it will have a number on it.
If the number is:
200 - You have a 24 GPD Membrane.
350 - You have a 36 GPD Membrane.
500 - You have a 50 GPD Membrane.
600 - You have a 75 GPD Membrane.
800 - You have a 100 GPD Membrane.
