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.
The Drain Waste and Vent (DWV) system is perhaps the. most important part of the total plumbing system in a. building. The DWV system is for the removal of waste. water and material from the building. Inspectors. recognize this portion of the plumbing system as a major. concern for not only the function of the plumbing but for. the protection of the health of the building occupants.
