Very easy to install. Directions were extremely complete. I made no mis-steps by following easy to follow directions. Got it installed and there were no leaks. I did mark each tubing end with a majic marker back about 1/2" before I inserted it in the connector to insure I got it all the way inserted and would have no leaks. By not marking the end, I would have only guessed that it was properly inserted all the way.

Great system!!! Thank you.
