What is A Bibcock?

Brass Bibcock?

Bibcock is a type of tap that is used to control the water flow of a water supply pipe or drain. To clarify, a bibcock is a wall-mounted water tap with a downward bent nozzle… that allows people to turn the water supply on and off. It is commonly used in outdoor areas or gardens, toilets, bathrooms, and sometimes in basins.

Types

Bibcock is a branch of taps. However, there are different types of bibcocks are available… and each style has its characteristics. In terms of structure, we can divide it into three types. Those are one way, two way, and long body. Moreover, bibcocks can be divided into functionalities, compressor/washer type, and slide type. 

Structure Of A Bibcock

There are many types of bibcocks available, but we are going to discuss the washer type. Certainly, this one is the primary and most used type. It consists of an inlet that connects with the main water supply line, an outlet that lets the water out, and a body. 

Firstly, if you look at a bibcock, you’ll see a handle connected with a rod or spindle and goes inside the body. This spindle has threads at its downward and a hole underneath. Right down of the handle, there is a packing nut and sometimes a cover. The nut keeps the handle and the tap body together. At the upper side of the body, there are also some threads carved. This is where the spindle sits inside the body. 

Also, there is a disc-type washer, and a small rod called a jumper. Here first, the washer jumps inside the jumper, then the jumper goes inside the spindle hole. Therefore, the washer cannot move. Just slide up and down. The washer sits on the valve seat.
