So, I tested the flow of my water in various configurations and found the following (all 4 of the following configurations include a backflow preventer and a fertilizer injector):
- With 1 hose in a bucket (off a Y splitter) and one hose (1 valve just shut), the flow is 247 GPH.
- With 1 hose in the bucket and 1 of the sprinklers, the flow to the bucket is 194 GPG so in that case the sprinkler was getting about 53 GPH, but it wasn't hitting a 50' circle, more like 15'.
- Now, the interesting part. With 2 hoses off the Y in the bucket, the flow is 277 GPH. So one of my standard garden hoses (5/8") seems to be able to support at most 240-250 GPH throughput.
- If I take the fertilizer injector out, the 2 hoses can fill the bucket at a rate of 300 GPH.
So, what does all this mean? It means that I can't run both sprinklers with the backflow and injector and expect to get 2 circles with a diameter of at least 25' which I need.
I considered running a 3/4" main to the patch and splitting to two 1/2" lines there, but that would mean I can't buy a second timer (damn budget), and the following solution works while allowing me to use some of the hoses I have and still buy a timer.
I can run one sprinkler (zone 1) by setting the timer for 30 minutes before I leave for work, then, right before I leave for work) shut off zone 1 and open zone 2 and the second 30 minute program will kick off shortly there after. Of course this means I will be going across the city to the second patch each morning too to do the same routine, but it's not far out of the way to my work.
Further, since I can't afford to buy a second injector for beta patch, I will rotate the fertilizations every other day and move the injector back and forth between patches.
I finally got it all figured out.
