Can anyone provide any information on these new drip irrigation fittings? RainBirds marketing material makes them sound like the best thing since sliced bread (but isn't that the purpose of any marketing department?). From what I can tell (because it isn't spelled out) it looks like they have these three sets of compression fittings (coupling, elbow, and tee) and they can take a range of tubing sizes AND adapters. The marketing claims that it's a quick and easy system to install, but I don't see ANY references as to weather you can ever take anything back apart. I'm going to be finishing up my drip irrigation system this summer, and IF these parts are easy to disconnect, I'd be interested in them. My design includes check valves (so that gallons of water don't soak the one plant at the bottom of the hill when the system shuts off), so I've got to do more disassymbly when I drain the system for winter.
