Aquasafe RO/DI?

[2pts]

I'm not a plumber, but I did most of the plumbing in my house when we built it, and have done several underground sprinkler systems. Never installed a RO/DI unit, but I can tell you for threaded joints, don't use that white tape.

Use the the yellow gasfitter's tape, it comes on the same type and size of roll as the white stuff, but it is much thicker and works so much better. You end up using way less of it too, when wrapping the thread, just make it one tape thick.

You can buy it at pretty much all plumbing supply places.
