jptrson Posted February 16, 2007 Share Posted February 16, 2007 I recently purchased a small brand new commercial RO system 500 gal per day. After about 6-7 hours of running time the membranes clogged up. I sent them back to the Mfg. and they could not recognize the substance on them. They said it felt a bit like a gel hand sanitizer?(scratch) Well they sent me new membranes, so before installing I ran the water for about 2 hours to flush the pipes, then ran the back flush on the system for another hour. Started the system up and ran great for about 6-7 hours and same thing happened. I called the city of Redmond ( they are investigeting now), but they say the ONLY thing they add to the water is chlorine and don't get my hopes up for them finding anything. I wanted to see if anyone has had a similar experience or any suggestions on what to look, test for. The system is located downtown Redmond.... city water.

andy Posted February 16, 2007 Share Posted February 16, 2007 You might try taking a water sample to the city for testing. Here in Vancouver, we can take a sample (well water, for instance) and have it tested for around $20. Just don't tell them it is city water...

jptrson Posted February 16, 2007 Author Share Posted February 16, 2007 I actually gave the city one of the membranes for testing. But then again, they want to know whats clogging it so they know what to test for? Duh! Quote Link to comment Share on other sites More sharing options...
fly guy Posted February 16, 2007 Share Posted February 16, 2007 that sucks. I think Nyles idea of tricking them into giving you an honest report of what it is in the water might very well be worth $20. Is it possible to get a sample of water from before the lines to your store start? Might at least be able to isolate if it is indeed a city problem or a landlord/personal problem. Sorry to hear :( Quote Link to comment Share on other sites More sharing options...

Yep, Sediment filter, then carbon block then the 2 membranes. Not sure how old the pipes are, but pretty sure over 10 years old Quote Link to comment Share on other sites More sharing options...
