Cleaning an airless paint sprayer

[Scott Radetich]

I purchased a 2016 Titan 440i sprayer on Craigslist  recently and used it this weekend.  How do you clean this thing?? I watched a few vids online and did what they said, but it took me forever, i mean like an hour plus while flushing the system out to get the color of the water to look a lot more like water vs the color of my paint.  Was i just overdoing it?  I mean i gave up and just packed it in after an hour, the water was still colored when flushing it out of the system but a lot closer to clear than an hour ago.   Day 2 and 3 i let the water sit in there several minutes between flushing it out to let the water do its trick, that reduced the amount of water i used, but my cleaning time was still an hour plus.

How do you normally clean out these sprayers?  Any tips appreciated.
