After putting the valve and various PVC fittings together I noticed that the sprinkler bar was well below the wheel well. After measuring, I determined that the bin and plumbing assembly had to be lifted about 6 inches. I didn't want to add that much weight to the bot so I constructed the platform to lift the bin out of fence boards ( 1"x6"x6"). The fence boards are extremely light and durable, readily available and are reasonably priced. Once the platform was constructed I cut a whole for the plumbing and installed small pieces of angle iron braces to hold the bin in place.
