• A drain, waste, and vent system (DWV) is a network of drainage pipes that transport used water from sinks, toilets, washing machines, showers and tubs out of a house and into a sewer or septic system.

    The "stack" is the main component of the drain system. All waste lines in a home connect to it. The stack is connected to the outbound sewer or septic line. The lower end of the stack generally begins in the basement or crawlspace. The upper end of the stack usually extends through a roof where it can transport sewer gases safely outside. The stack acts as a vent in this case and also helps promote drain flow by drawing air inward. Trapped sewer gases not only smell but can be hazardous. Plugged stacks can trap gases and prevent drainage from a house.

    Copper DWV fittings have great thermal conductivity, are resistant to corrosion, and are highly durable. Copper DWV fittings eliminate brown water problems and must be soldered to prevent leaks.

    There are many different types of copper DWV fittings, each serving a particular function.

    45 & 90 Degree Elbows are used to change the direction of the flow of water 45 or 90 degrees. These fittings are connected directly to a copper DWV pipe.

    45 & 90 Street Elbows are also used to change the direction of the flow of water 45 or 90 degrees. Unlike a standard elbow, a street elbow is connected to a copper DWV fitting.

    Couplings are used to connect two pieces of copper DWV pipe together.

    Caps are used to cover the outside end of a copper DWV pipe.

    Tee Fittings are used to either combine or split fluid flow. They are also used to connect pipes of different diameters or for changing the direction of pipe runs.

    We offer a wide selection of copper DWV fittings manufactured by Cello.
