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 Main Vent Stack. The main vent is stack is often, but not always, a continuation of the soil stack, which is a 3- or 4-inch waste pipe that extends vertically down from the uppermost bathroom to the sewer.ndividual vents must rise above the overflow line of the topmost plumbing fixture in the house before you can tie it to the main vent stack. This is a precaution that prevents the vent from becoming a drain if that fixture's drain gets blocked.
