I was in Lowes so I decided while I was there to picked up some tubing and a few parts. When I went to use them the tubing and parts were much smaller than what I had. I had got my drip system from Home Depot and was by Dig. Not only is the Dig brand bigger but also the walls are thicker and it is a much better system. To be able to use the pipe I got from Lowes I wrapped electrical tape around the tube at the connection to make it thicker. If you get a system check them out and stick with one brand or make sure they are the same size.
