Hey speeds207, I don't know how much research you've done on drug tests, but I can tell you right now that I'm dirty(took a home test for THC yesterday because I'm fixing to get a job) and I haven't smoked since early July. That is a little over two months. THC stores in your fat cells so unless you have a roadrunner type metabolism you will piss dirty. The water just dilutes your sample to below the 50 ng/ml cutoff for drug tests. Also THC is not water-solluable so just drinking water doesn't get it out of your fat. Now you adding water to your sample might have saved your ass because you might have diluted it enough to get it below that cutoff level. The hair isn't going to help, that would just make them suspicious because unless it was a pube, how the hell did hair get there. Spitting in it won't do it because your saliva can also contain the tell-tale indicators of weed. Until two months ago I smoked at least 5-6 dro bowls daily(wish I still could)for at least 8 years and so believe me when I say I truly do wish you the best of luck. Oh, a helpful tip for future reference. Go and get some Opcon-A from Baush & Lomb. They are eye drops that burn like hell, but will keep you eyes ultra white even after 2-3 smokings. My eyes would glow from the black lights in clubs they were so white. Again, good luck.
