Cobalt Posted October 2, 2007 Share Posted October 2, 2007 Well, my RO unit was working fine until last week and I noticed no pressure at the sink tap. went to the basement and the waste was running full blast. I figured the pressure valve went bad, so I ordered a replacement. It arrived today and I installed it, the waste still flows when I have my output shutoff. So I inspected the check valve, and it appears to be operational, but I don't know for sure (don't have the extra parts to be able to test it). Anyone know where to find the RO unit fitting locally? I don't recall seeing a check valve at Lowes or home depot. Or better yet does anyone have any ideas would be wrong? TIA Quote Link to comment Share on other sites More sharing options...
Cobalt Posted October 17, 2007 Author Share Posted October 17, 2007 found the problem i think. my sediment filter was not seated properly so both carbon blocks plugged quickly. I replaced the filters but it is still not shutting off, so who knows. I replaced the check valve too. Now all I can figure is that the plugged carbon blocks may have allowed chlorine to get to the RO membrane and destroyed it?? I don't know. I guess that is next to replace... sheesh...
