Sorry, I don't post much but am in need of a bit of help.
I bought an second hand Xline System RO/DI last year but I seem to be going through membranes way too quick. I live in Southampton so the water quality is rubbish (reading 311 this morning) but it still doesn't seem to last as long...
I've just moved house but before I moved I thought I needed new RO membranes as I was only getting 12ppm product water with 40psi tap pressure.
At the new house the mains pressure is 51psi and I'm now getting 1ppm! :1f603:
I knew extra pressure helped but not that much!
