Thanks guys, I appreciate the efforts to answer my questions. I am learning a lot in the process. I have learnt that I am in a precarious position with my application. I don't run the RO for long periods and it switches on and of numerous times per day. I am not in a position to use softeners...

Dear @ashtree It has been a while since your last post, for which I am very thankful. I managed to find a simple solution to fill a pressure tank with permeate and have that line re-enter the source line with non returns. Then when the system shuts down the permeate flows out into the membrane...

@ashtree, Your last post has been very helpful! Thank you very much for that insight. If you don't mind, please elaborate on the effect a permeate flush would have on scaling? I am considering small RO controllers for my systems which have the option to open an additional solenoid to run...

Thank you so much @bimr At least knowing that Siliphos is not an option, allows for me to focus on other aspects. Also, you are saying that lower pressure and flow in the membrane is not a bad thing. The question just beckons how high my pressure should be to get good performance vs. not...
