Has anyone had trouble with the unions supplied w the Red Sea Reefer 350? The red gasket does not seem to do the trick? Has anyone used plumbers tape on the junction to help seal the joint? Don?t know why its happening but perhaps a replacement gasket is in order...
plumbers tape all of it. I even let it be for a long time til I decided enough is enough. Drained the back of the return behind the tank. Removed all the 3 pipes one by one. Added tape on the top pipes and also on the bottom. No problems after that.
