This 20' section of tubing works perfectly for my excessive water runoff.  Previously I did not use a connector; however, this time I added a connector and it still works well but with less leakage.  The tubing itself was originally too long but with a little cut in half I now have two hoses and the other one will have its us at another runoff spot.  My objective was to remove water too close to the house's foundation to a better spot.  This tubing worked perfectly and as long as nothing clogs the source all is well.  In a few years I'll be back to get another one to replace this one.  I expect weather to wear it out and not use.
