Aren't these supposed to disconnect when you squeeze the white tabs? Either I'm doing something wrong or this is a complete failure of a design. Does anybody know how to operate this "quick disconnect". I don't want to start mangling things in frustration. Any suggestions are much appreciated.

 

No. They require a tool that pushes inside the connector.

 

I wonder what the white tabs are for that clearly are there to be squeezed inward? Anyway, I managed to clear enough barb to attach the hose tightly with a hose clamp instead of trying to use that connector.

 

probably to help guide the tool into the connector

 

I was able to remove the tee with no special tools. Followed this video and it was very helpful.

 

Thanks for following up. So what were you doing wrong the first time?
