I had a very small crack in my ro water line today and no union! What to do? Well I will tell you…you make a MacGyver fitting!
My spot free water was not working so I took a look at it and the first problem (first picture) the multistage pump head fell off. It just cracked off, actually rusted off. Then the second problem is the ro system was not producing water and the delivery procom 1/2 hp motor seems death. I guess the freeze knocked both of them out? Greg told me both are over 15 years old.
