The double ell should be placed on a brick or stone and leveled so its perfectly flat. To get an equal split, you need a straight run of at least 2 feet entering the fitting, if you don't have this distance the water may not be equally divided. Typically a 2" double ell is only used in the first split, 1.5" double ells are used after that since there is less water.

Underground Emitter Box

The underground emitter box, or "mulch shield"  is used to create a subsurface irrigation area, where the greywater can flow out into the mulch. The air gap between the outlet and the mulch prevents roots from growing back into the pipe and clogging the system.

You'll need to drill your own hole for the greywater tube to enter the valve box. You will most often want this to be just about 2 inches below the lid.

The valve box, or "mulch shield" should be sitting on top of a thick (4-6") layer of mulch.
