  2. Drain-waste-vent system - Wikipedia

    en.wikipedia.org/wiki/Drain-waste-vent_system

    A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.

  3. Air lock - Wikipedia

    en.wikipedia.org/wiki/Air_lock

    Depending on the pipe layout – if there are any upside down 'U's in the circuit – it will be necessary to vent the highest point(s). Otherwise, air lock may cause waterfall flow where the loss of hydraulic head is equal to the height of airlock; If the hydraulic grade line drops below the output of the pipe, the flow through that part of ...

  4. Plumbing fixture - Wikipedia

    en.wikipedia.org/wiki/Plumbing_fixture

    The visible water surface in a toilet is the top of the trap's water seal. Each fixture drain, with exceptions, must be vented so that negative air pressure in the drain cannot siphon the trap dry, to prevent positive air pressure in the sewer from forcing gases past the water seal, and to prevent explosive sewer gas buildup.

  5. Air gap (plumbing) - Wikipedia

    en.wikipedia.org/wiki/Air_gap_(plumbing)

    This "air gap" is visible above the sink as a small cylindrical fixture mounted near the faucet. In the base cabinet under the sink, the drain hose from the dishwasher feeds the "top" of the air gap, and the "bottom" of the air gap is plumbed into the sink drain below the basket, or into a garbage disposal unit. When installed and maintained ...

  6. Automatic bleeding valve - Wikipedia

    en.wikipedia.org/wiki/Automatic_bleeding_valve

    The valve must always be installed vertically, usually at the top of a short vertical pipe. If the valve body is filled with water, the float moves upwards and closes the valve. If air collects in the valve body, the waterline lowers, as does the float, and the valve opens to release it. [4]

  7. Furnace (central heating) - Wikipedia

    en.wikipedia.org/wiki/Furnace_(central_heating)

    The vent pipes, also known as the exhaust system, are often installed using PVC pipe instead of metal venting pipe to prevent corrosion, but this will vary based on geographical location of the installation and local regulations. The draft inducer allows for the exhaust piping to be routed vertically or horizontally as it exits the structure.

  8. Trap (plumbing) - Wikipedia

    en.wikipedia.org/wiki/Trap_(plumbing)

    Trap with copper drain pipe at underside of firestop packing in two-hour fire-resistance rated concrete floor slab Typical P-trap. Maintaining the water seal is critical to trap operation; traps might dry out, and poor venting can suction or blow water out of the traps. This is usually avoided by venting the drain pipes downstream of the trap ...

  9. Sanitary manhole - Wikipedia

    en.wikipedia.org/wiki/Sanitary_manhole

    In a plunging drop manhole, a vertical pipe is used to allow the flow from a higher elevation to drop down directly to the manhole base within that vertical pipe. [26] The vertical pipe of a plunging drop manhole (known as a drop pipe) can be configured in two ways. One way is to have the drop pipe inside the manhole.
