Exactly the same block lived in our house for 8 years and finally died. We liked the system so much that we bought it again. This unit is the same except for the shut off valve on the reverse osmosis tank (see photo). You cannot remove the connector from the tank without this valve. I made the mistake of removing the hose from the tank without disconnecting it and spraying water everywhere. On the last device I removed the non-return valve and reinstalled it. All in all a great system but buy a check valve from Home Depot or something.
