If i understand your question right, you wanna know if you can drink large amounts of water to the point that youre basically pissing out very dilute urine. I can tell you that the when i was on methadone
treatment, we had supervised urine drug
screens where obviously you could not do much besides cross your fingers and hope it came out clean.
My point is, i was still using ocassionally so i remember for a couple of these i know i had used within a day or so and just drank tons of water and urinated multiple times before going in to give my urine and came out clean. however, they sent these off to the lab because obvoiously they have to isolate different opiates
since we obviously would be positive for one already (methadone) . So as far as not coming up positive for an opiate
this method has worked for me more than once.
The downside to this is that the lab also checks for creatinine levels in your urine which are basically naturally occuring substances in the urine which they use to determine that the sample isnt just water or whatever. This is not to be confused with creatine, which sometimes is used for detox i really dont know how that works. So like you said they may question you about this and ask you to give them your first piss of the day next time or accuse you of trying to dilute your piss, although with me we were monitored so theres not much they can do. And even if this is the case it should as you said, buy you more time until you are hopefully legitimally clean.
Obviously i cant guarantee this will work for you, it definitely depends on multiple factors such as how much/how long you were using, what opiate, and your metabolism etc. But i can say it has worked for me. It is really nothing more than watering down your urine, only by drinking mass amounts of water instead of adding it to the sample. So the more water you drink the more less concentrated your urine will be, its pretty simple. And once again a main part of this is to try and urinate as many times as you can prior to giving the sample because your urine will be far more concentrated with your first of the day, and if you keep putting down water, should get more dilute each time.
Remember this is not a fail safe plan, if there are drugs
in your system theres only so mich you can do short of providing someone elses clean urine. However, this plan definitely cant hurt your chances and it has worked for me when ive been in pretty much the same position. Hope this helps you, sorry its so long.
Good luck buddy

Oh and yes the clearer the better, dont give them the first thing in the morning dark/yellow color it will have the most concentration. the clearer it is the more likely it is closer to being diluted with water which if you are drinking enough of it, thats basically what will be coming out.
