Plumbers often use PVC pipes.
A sanitary tee is a plumbing fixture that allows liquids to drain while allowing ventilation of the plumbing system. Fit resembles a regular T-fit; However, the toilet T, when viewed from the side, will have a definite sweep towards the central entrance. This scavenging feature molded into the T helps fluid on its way to a drain tube. The upper tee fitting is connected to the building’s plumbing vent system.
Polyvinyl chloride (PVC) plumbing makes plumbing much easier for most inexperienced plumbers than copper or black pipe. In many cases where a drain is installed where there was no drain before, it is necessary not only to install the drain, but also to install a ventilation system for the drain. The hygienic shirt makes adding a method of ventilation a breeze. By adding the sanitary tee to the drain line, the vent can be piped directly from the top of the tee, making the whole procedure easier.
When connecting a vent line from a sanitary tee, it is imperative that the vent does not connect below any other drain. This could make it possible to drain sewage or liquid through the tee and even send it back to another device, such as a sink. All PVC pipe exiting the vent systems must be tied over all drains in the structure and then vented to atmosphere through the roof.
The curved center section of the Hygienic T discourages siphoning of sink drains and drains when installed correctly. Improper installation of the connection can cause drainage difficulties for the drainage system in which it is installed. One sign of a malfunctioning tee is a gurgling and noise from the drain running into the tee. A clogged vent gives the effect of spilling milk from a pitcher. Without proper airflow and ventilation, milk flows in and out of the pitcher.
Sanitary tees should not be used in place of drainage traps. The trap is an important element in the plumbing system. Prevents gases from the sewer system from entering the structure through the sink drain. The tee simply helps the drain out of the sink and release any gas or odors through the vent system. It is important to ensure proper sealing of any joints when assembling a ventilation system. Steam, condensation, and even rainwater can enter the vent pipe. A poor seal at any joint can lead to damage to ceilings and walls.
