That's not the problem. I can, with a bit of force, push the black
tubing on to the drippers/connectors/T-pieces. What IS the problem is
that the tube has its own idea as to where to form loops and turns and
it's a heck of a job to keep it straight. Whereas a thin copper tube
would not have that problem.
