Yes. The 1st stage sediment filter must be a 5 Micron, 10″ cartridge. The 2nd stage filter is more crucial. A purification grade carbon must be used, also 10″ length. Premier recommends the customer use Premier’s G.A.C. 56 cubic inch carbon filter because our filters have more carbon than others, therefore, better filtration. The system’s various components are designed to enhance each other, thus the system will work much better. You can use other carbon filters; however, you may need to replace them more often due to their smaller volume of carbon.
Yes. It is highly recommended. The Premier R.O. system has been designed to operate best to give high quality purified water with normal routine maintenance. By changing the pre-filters on a regular six-month basis, you will eliminate dirt and chemicals in the water that will plug the membrane. After six months of use, the carbon filters can have bacteria growing within the filter media. Your local water conditions may necessitate more frequent filter changes.
Yes. Iron will plug a R.O. membrane, as the membrane is not able to flush iron out. Trace amounts of iron (up to 2 PPM) can be removed by a water softener. If the water contains 1 PPM or less, there is no need for concern as the membrane will usually last 1-2 years. Note: This refers to clear water iron, not red iron. The difference is that clear water iron leaves no visible signs, whereas red iron leaves a reddish brown discoloration in toilet bowls, tanks, sinks and tubs. If red iron is present, steps to remove the iron will have to be taken, otherwise the warranty will be void.
It is the pressure of water that forces the water through the membrane for purification and flushes the rejected solids away. Low water pressure will result in reduced production and premature fouling of the membrane. The ideal pressure for operating an R.O. system is 60 PSI. Pressure below 40 PSI is generally considered insufficient, and should be boosted using a pressure booster pump.
