+Capt. Obvious Posted October 26, 2012 Share Posted October 26, 2012 I have a Maxxima RoDI unit that I purchased and installed an ASO on, however, when my reservoir float switch is closed waste water continues to run, what am I doing wrong here? I am wasting tons of water and have to remember to manually shut off the water each time (1st world problems) Any ideas? I have checked the valve itself and it seems to be fine.but even upon inspection and reassembly it is still not shutting off supply water to the membrane.

victoly Posted October 26, 2012 Share Posted October 26, 2012 has it ever worked or did it recently fail? Link to comment Share on other sites More sharing options...

victoly Posted October 26, 2012 Share Posted October 26, 2012 do you have a check valve installed? Link to comment Share on other sites More sharing options...

+Capt. Obvious Posted October 26, 2012 Author Share Posted October 26, 2012 Yes, watched that already, and with and without the valve installed the ASO still never shuts down the feed Link to comment Share on other sites More sharing options...
victoly Posted October 26, 2012 Share Posted October 26, 2012 hows your inlet pressure? Link to comment Share on other sites More sharing options...
+Capt. Obvious Posted October 26, 2012 Author Share Posted October 26, 2012 according to the gauge on the membrane housing...pretty low...looks like ...1psi? Link to comment Share on other sites More sharing options...
+Capt. Obvious Posted October 26, 2012 Author Share Posted October 26, 2012 Correction 12psi (approx 1 bar) Link to comment Share on other sites More sharing options...
victoly Posted October 26, 2012 Share Posted October 26, 2012 that doesn't seem right....your incoming pressure should be like 40-50psi. Do you have a gauge that you can check your house pressure at a hose outlet? I'm a little surprised that you're even getting water through the RO membrane at all at 12 psi.

Juiceman Posted October 26, 2012 Share Posted October 26, 2012 Yeah, that's super lower to begin with. That's probably why it's not shutting off. The pressures not building at the chevkvalve Link to comment Share on other sites More sharing options...
(Bio)³ Posted October 26, 2012 Share Posted October 26, 2012 Had this same thing happen about 2-3 months ago. Internal diaphragm was stretched, everything looked fine to my eye. I have 47PSI, once I replaced the ASOV everything worked fine. I also replaced the check valve at the same time. Link to comment Share on other sites More sharing options...
+Capt. Obvious Posted October 26, 2012 Author Share Posted October 26, 2012 well I am mildy concerned about the pressure...could it be my filters need replacing? Link to comment Share on other sites More sharing options...
