Most municipal building codes mandate that drain plumbing increase in diameter as it moves closer to the municipal sewer system. i.e., most kitchen sinks evacuate water with a 1 + 1 ⁄ 2-inch drain pipe, which feeds into a larger 4-inch drain pipe on the main plumbing stack before heading to a septic tank or to the city sewage system. This ...
An elbow is installed between two lengths of pipe (or tubing) to allow a change of direction, usually a 90° or 45° angle; 22.5° elbows are also available. The ends may be machined for butt welding, threaded (usually female), or socketed. When the ends differ in size, it is known as a reducing (or reducer) elbow.
All well washers are installed with RPZ Devices in case a pumping station breaks down, and the sewerage level rises above the well washer, causing backflow down the water supply line. A reduced pressure zone device is tested with a device called a differential gauge.
This type of washer is especially effective as a lock washer when used with a soft substrate, such as aluminium or plastic, [8] and can resist rotation more than a plain washer on hard surfaces, as the tension between washer and the surface is applied over a much smaller area (the teeth). There are four types: internal, external, combination ...
The same fitting can be used in reverse as an eccentric increaser or expander. They are used where the diameter of the pipe on the upstream side of the fitting (i.e. where flow is coming from) is larger than the downstream side, and where there is a danger that vapour may accumulate. [1]
A conduit system can be made waterproof or submersible. Metal conduit can be used to shield sensitive circuits from electromagnetic interference, and also can prevent emission of such interference from enclosed power cables. Non-metallic conduits resist corrosion and are light-weight, reducing installation labor cost.
