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.
For example, a 32mm waste from a wash hand basin is connected to a 100mm diameter Soil and Vent pipe. 9. Waste pipes from appliances which discharge into pipes of the same diameter have limitations on lengths, number of bends and gradients to minimise siphonage problems.. Foul water is soil water from toilets and waste water from basins, baths, showers, etc. 2. The one-pipe system is favoured over the two-pipe system because there are fewer pipes and it is more hygienic. 3.
