Kenmore Ultrafilter 150 RO System
Our system has been working flawlessly for years and years, up until now. Here's the set of problems we've fixed, and how we have fixed them. However, the tank is not getting filled at all - even after hours and hours. Still bone dry empty.
First two issues we had to correct:
1) water was leaking from the "shutoff assembly" - we replaced that assembly (including the diaphragm, plunger, o-ring, spring, ball, etc). Fixed that leak.
2) system was not producing much product water, maybe a cup of water would come out the faucet - we checked the tank pressure PSI and water came out the schrader PSI pressure valve on the tank - that told us the tank bladder or diaphragm was broken - even pumping up the tank with more air pressure - we could hear the whooshing noise, and more water our the air value - which should be bone dry. - So we replaced the tank - brand new tank.
System should be good to go - put in new filters and RO cartridge.
After hours (days), the tank is still empty. No water in the tank.
Could there be a further problem with the shutoff assembly? What do you think we should try next?
