I had to fix my ASO value that would not operate correctly: 1) Make SURE you understand the IN & OUT ports and hook up the lines correctly to ASO valve. 2) Use ONLY hard lines to interconnect (dont use clear lines from home depot, they are too soft and value wont shutoff correctly). 3) Keep all hard tube lengths to ASO value as short as possible. 4) On all connections make sure the tubes push all the way down 5) On all post carbon filters, post filters, etc...dont plug directly into these filters, first always use a push in connector then push your tube into those connectors. I did all above and fixed my ASO value RO system operation.
Thanks for good tips. I have 2 ro systems. On one system the ASOV opens almost immidiately when a cup of water is drawn from tank and we love this way. On the other system, ASOV doesn't open until about 1 gal of water is drawn from ro faucet. We don't like this way because the output pressure is weak for a long period of time. Please let me know what is the normal on/off behavior of ASOV. Thanks in advance
I installed one of these and it wasn't working. I found out either the check valve wasn't working or the system I installed didn't have one. The shutoff valve would just vibrate and let waste water to pass even though my tank was full. I happen to have a separate check valve that I was able to install and it solved the issue. On my system I have it filling a barrel with a float valve and not a pressure tank, this may have been the reason it wasn't working.
This valve does not have any electrical connections like a high pressure switch so really very confused how can it shut of an RO booster pump or this is only for non electric systems?
