Flow splitter
This is a flow splitter in accessible area. A stone normally covers the splitter.
This flow splitter divides greywater flow into two equal parts. The splitter needs to be level, like on a brick, and to ensure an even split the pipe coming in should be straight for 2 feet. If a curved pipe comes into the splitter the water won't divide equally. For later inspection purposes, a hole is made in the top of the ell and a threaded cap is placeable in this hole.
