Fermented Feed I started thinking about using this idea to supplement the chickens winter feed. I bought a 40 lb. bag of hay cubes, about 2x 2 wide. While I didn't ferment mine, I soaked them in really hot water, for about 30 minutes. The first 2 times the girls just looked at it. After that, all gone! I guess they liked it. Another good reason to read lots of blogs.
Soil stack (in green) is connected to the sewer at the bottom and vented at the top, while each plumbing fixture has its own trap (shown in white) In modern plumbing, a drain-waste-vent (or DWV) is part of a system that removes sewage and greywater from a building, and regulates air pressure in the waste-system pipes to aid free flow. Waste is produced at fixtures such as toilets, sinks, and showers, and exits the fixtures through a trap, a dipped section of pipe that always contains water.
A toilet waste system begins at the toilet flange. The start of a toilet waste system is the toilet's own waste outlet, while the main pipe is the soil stack. The stack is a 3-inch or 4-inch length of vertical pipe that drops to the sewer and is connected to a 2-inch pipe that rises through the roof to provide venting. To connect a new toilet to an existing stack, you need three basic fittings.
