Taps play a very important role in our daily lives. From various water taps, bib taps or bibcocks are the most popular and used by people. We may see and use it every day, but we don’t know much about it. This is why this article has been prepared for you to discuss in detail about the bibcock. So, let’s break it down.

The world of plumbing and water management is vast, with many intricate tools and components that help us control and direct the flow of water in our homes and industries. Among these tools, the bibcock valve stands out as a unique and often underappreciated component.

Introduction to the Bibcock Valve

Bibcock is a tap 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, gardens, toilets, bathrooms, and sometimes basins.

At its core, the bibcock valve, commonly known as “bibcock,” is a faucet or tap that provides controlled access to water or other fluids. While it might appear as just another tap to many, its specific design and mechanism suit it for certain applications.

Bibcock is a branch of taps. However, 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. 

Understanding its Design and Mechanics

A standard bibcock valve comprises:

  • Spout: The elongated outlet from which water is dispensed.
  • Handle: Used to control the flow of water, often designed ergonomically.
  • Valve Mechanism: This includes washers, seals, or ceramic plates to control the flow and prevent leaks.

Structure Of A Bibcock

Many types of bibcocks are available, but we will 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, looking at a bibcock, you’ll see a handle connected with a rod or spindle inside the body. This spindle has threads at its downward and a hole underneath. Right down the handle, there is a packing nut and sometimes a cover. The nut keeps the handle and the tap body together. There are also some carved threads on the body’s upper side. 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, and 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.

Bibcocks have male threads on the inlet. But some have outlet threads, too. The outlet thread helps you to connect pipes from outside.

Materials of Bibcock Valves

Bibcock valves can be crafted from a variety of materials, each chosen based on its inherent qualities, which make it suitable for particular settings and purposes:

  • Brass: This is one of the most preferred materials for bibcock valves, primarily because of its robustness and resilience to corrosion. Brass bibcocks have a longer life, and their gleaming finish lends an aesthetic appeal.
  • Stainless Steel: Renowned for its corrosion resistance and sleek appearance, stainless steel is another popular choice. It can handle extreme temperatures and is quite sturdy.
  • Plastic or PVC: These are lightweight, corrosion-resistant, and are typically used for specific applications such as garden taps or in environments where the weight of the bibcock is a concern.
  • Cast Iron: Known for its incredible strength and durability, cast iron bibcocks are perfect for heavy-duty applications where the valve will face a lot of wear and tear.
  • Zinc Alloy: Offering a balance between strength and malleability, zinc alloy bibcocks are corrosion-resistant and usually more affordable than their brass or stainless steel counterparts. The alloy can be shaped into intricate designs, making it suitable for more decorative bibcock variants.

Advancements and Modern Innovations in Bibcock Valves

Over time, the humble bibcock has undergone significant refinements and innovations to serve modern requirements better:

  1. Frost-Free Bibcocks: These valves are engineered to resist freezing in cold temperatures, ensuring that water flow remains uninterrupted even during chilly winters.
  2. Lockable Designs: With security becoming a prime concern, especially in public spaces or locations vulnerable to water theft, lockable bibcocks offer a solution by preventing unauthorized access.
  3. Sensor-operated Bibcocks: Touchless technology has made its way to bibcocks as well, where sensors can detect hand movement and turn on or off the flow, ensuring optimal hygiene, especially in public restrooms or health-centric environments.

Applications of Bibcock Valves

The versatility of bibcock valves ensures they have a broad spectrum of applications:

  • Household Use: Commonly found as garden taps, providing controlled water access for watering plants. They can also be spotted in kitchens and bathrooms as faucets.
  • Industrial Settings: In factories or large-scale facilities, bibcocks help in managing access to various liquids, not just water. They could be part of cooling systems, lubrication mechanisms, or chemical processing units.
  • Agriculture: Farmers employ bibcocks in irrigation systems, allowing controlled water distribution to various parts of a field or garden.
  • Public Spaces: Bibcocks can be found in parks, public restrooms, and schools. The ease of control they offer makes them ideal for such settings.
  • Laboratories: Due to their precision and easy control, bibcock valves are also used in laboratories where specific amounts of liquid are required for experiments.

How A Bibcock Valve Works

Okay, so what does a bibcock do? It connects to the water distribution pipe and controls the flow of water… when you turn it on, water comes out, and water flow stops when you turn it off. Now, let’s see how.

You spin the handle anti-clockwise when you try to turn it on. For every backspin, the spindle moves through the thread and releases pressure from the washer. When the spindle moves a certain distance, it allows the washer to slide up. After that, the water pressure from the main pipe pushes the washer up from the valve seat. As a result, the valve seat opens, and the water comes out.

And when you want to turn it off, you’ve to spin the handle clockwise. Therefore, the spindle goes down through the thread and pushes the washer down. Then, the washer seals the valve seat and cannot move up for the spindle pressure. As a result, the water flow stops


You can use it indoors and outdoors, and the media can be water, gas, or other liquids. In indoor, it’s suitable for kitchen sinks, toilets, and bathroom sinks or water supply. Similarly, it can help you provide an external water supply to your garden or outside your home. Moreover, it also does an excellent job in industrial areas and other open places.

Most Common Problems And Solution

The most common problems of a bibcock are thread brooks inside, the washer not working, and leakages. These problems occur when it’s getting old. Most of the time, you cannot repair it, and replacing it is the only solution.

How To Replace A Bibcock Valve

Replacing an old bibcock with a new one is a pretty simple task. And installing a new one is also similar. If you follow these steps correctly, you’ll be able to install or replace a bibcock. The steps are:

· First of all, turn off the water supply from the plumbing pipe system

· Now, grab the tap with your hands or a wrench and spin the whole thing anti-clockwise until it comes out.

· Clean the entrance of the water supply pipe as much as possible.

· Wrap some thread seal tape at the inlet thread. 

· Insert the inlet into the pipe and rotate it clockwise. Make it as tight as possible, and the nozzle should be downward

· At last, turn on the water supply and test it.

Difference Between Tap And Bibcock

Yes, Tap and Bibcock both do the same thing in the same way. But they are different. Tap means the root, but bibcock is like a leaf of the tap. Tap can stand alone, but the bibcock is always wall-mounted. The tap usually comes with a slide function, and the bibcock usually comes with a thread or washer function.
