If you’re installing a drain or vent for your home, it is important to understand how the drain and vent system works. You can identify these types of drains and vents by the orientation of the pipes. They can either be horizontal or vertical, and there are several types of connections available.

Often referred to as bleeds, process vents and drains are integral parts of piping systems. They are small, accessible openings that are shut when a process is finished. During the design stage of a process, the process engineer determines which vents and drains are needed and where they should be located.
Vents and drains are designed to reduce pressure drop and maintain proper piping system pressure. Vents are also used for hydro-testing piping systems. Typically, they are used in the initial construction of a plant or during modifications to the system. They may not contain valves. Some plants install temporary valves in hydro-test vents and remove them after testing. Others retain the valves installed in hydro-test vents.
Vents and drains are often placed at high and low points of the piping system, which makes them necessary for hydrostatic leak tests. Vents should be at least three meters above the highest level of piping. They should be oriented according to the prevailing wind direction. Ideally, they should be located next to a safe escape route. Additionally, water-cooled equipment must be checked for suitable cooling water pressure and must be connected to a booster pump. Alternatively, a vacuum breaker can be installed to draw in air or process gas.
The piping and instrumentation diagrams must indicate the location of the vents and drains. If they are required, they should also indicate the type and size of valves and connections. The piping and instrumentation diagrams must also specify the piping and valves needed to start and shut down the plant.
Creating a horizontal to horizontal drain connection involves using a special plumbing fitting. In the case of horizontal drain connections, the fitting is called a double sanitary tee or double combination wye. It has a downward sweep design that directs flow to the pipe wall opposite the outlet opening.
However, there are some things to keep in mind. Horizontal drain pipes flow primarily by gravity, so they need a little nudge at the corner to guide the waste. This is required by the International Plumbing Code in section 706.3. In addition, the fitting should have a directional nudge.
Horizontal drainage lines must connect with other horizontal drainage lines and vertical drainage lines. The connections must be made through 45-degree “Y” branches, long-turn “TY” branches, and other approved fittings. In some cases, horizontal to horizontal connections can also involve a combination of fittings with an equivalent sweep. For the most efficient connection, the horizontal to horizontal pipe connections must be made through 45-degree fittings.
The horizontal drain length must be sufficient to prevent clogs and ensure adequate drainage. A horizontal drain should be about sixty meters (200 feet) long. Ideally, it should be long enough to draw water away from any potential slide mass. The design of horizontal drains should incorporate multiple cross-sections of the critical failure surfaces and geologic and hydrologic profiles. Horizontal drains may be installed at multiple elevations, although the lowest elevation will typically produce the greatest water table drawdown.
Horizontal to horizontal drain connections can be made by running a horizontal pipe up to an existing pipe. The pipe must be inserted between studs at intervals of about one-eighth to four inches for each running foot. The horizontal pipe must be marked with alignment marks so that it can be cut and reassembled properly.
A PUSH-ON OUTLET drain connecting a pipe to a drain body is a labor-saving method for connecting a pipe to a drain. These drains feature a rubber gasket that is designed to press against the stub end of a pipe. They also feature fins around the gasket to prevent water leakage. The connection is made with a threaded connection to fit either a BSPT or NPT standard pipe. If you use a non-threaded pipe, you can use an adaptor that is positioned between the body of the drain and the outlet end of the pipe.
