Hi, 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...

HI all I bought a new 450gpd RO/DI system which is temporarily set up until I make a permanent place for water purification (I have to set up and put away when not in use). when I connect water mains to the RO I always open the flush tap for a couple of mins before closing and putting pure water...

Hi lads Im desperate for any help with changing my ro membrane over. Everything went fine,more or less,until i tried to place the end cap back on with the new membrane inside.  The video i watched was good and at the end said use a club hammer to get the cap back on tightly. I hammered the cap...

I've always been good at changing my filters as per the recommendations, flushing regularly etc etc. The unit is kept away from frost and I like to think well looked after. The issue I always had was...

Hello Guys, I just joined the forum at the suggestion of a RO systems supplier I have been pestering to get your opinion on an improvement to RO system efficiency and water flow rates. I have a relatively cheap simple idea that will get the RO filters running at or above there quoted flowrates...

Firstly, sincere apologies, I'm sure this has been posted several times but I can't find what I need by searching. So i need to move to RO because DI vessels are costing me a fortune. I don't really understand how an RO system works or the particulars of the set up. I've just checked I get...

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!
