What is the difference between a pillar tap and a bib tap?

Introduction:

Pillar taps and bib taps are two common types of taps used in plumbing systems. They have their own unique features and uses, and it is important to understand the differences between them to make an informed decision when selecting the right tap for a particular application. This article will compare and contrast pillar taps and bib taps based on their design, construction, applications, and other characteristics.

Design and Construction: Pillar taps, also known as basin taps or sink taps, have a classic design with separate hot and cold taps mounted on a vertical surface or platform. They usually have a knob or lever handle that rotates to control water flow. Pillar taps can be found in a variety of materials, including chrome, brass, and stainless steel. They are commonly installed in kitchens, bathrooms, and other indoor spaces.

In contrast, bib taps, also called garden taps or outdoor taps, have a horizontal spout connected to a vertical cylindrical body. They are designed for outdoor use and are primarily made of brass due to its corrosion-resistant properties. Bib taps typically have only one handle or lever to control water flow. They are often mounted on external walls or structures and are frequently used in gardens, garages, and other outdoor areas.

Water Flow Control Mechanism:

Pillar taps and bib taps have different mechanisms for controlling water flow. Pillar taps usually employ ceramic disc valves that regulate the flow and mix of hot and cold water. The ceramic discs are fitted onto the valve spindle and rotate against each other to either allow or block the flow of water. This mechanism provides precise control over water flow and temperature.

Bib taps, on the other hand, typically use a simple valve mechanism with a rubber washer or valve disc. The handle or lever attaches to a spindle that opens or closes the valve by moving the washer or disc. This mechanism is straightforward and easy to repair but provides less precise control over water flow and temperature.

Water Pressure and Flow:

Pillar taps and bib taps also differ in their water pressure and flow capabilities. Pillar taps operate well under a range of water pressures, and they usually have an aerator that reduces the flow rate and improves the quality of the water stream by creating bubbles. They are popular for sinks and basins because they provide a controlled flow that is easy to direct and suitable for tasks such as washing dishes or hands.

Bib taps are typically designed for use with low-pressure water systems, and they provide high flow rates suitable for outdoor activities such as watering plants or cleaning. They typically do not have an aerator or other flow-restricting devices, which allows for greater water output but may result in splashing and waste if not used carefully.

Applications:

Pillar taps and bib taps are used in different applications. Pillar taps are commonly found in residential and commercial buildings, primarily in kitchens and bathrooms. They are appropriate for tasks such as washing hands, filling sinks or basins, and operating showers or bathtubs. They provide accurate temperature mixing and precise water flow control.

Bib taps are designed for outdoor use and can be found in gardens, garages, recreational areas, and industrial sites. They are ideal for activities like watering plants, cleaning outdoor spaces, and connecting hoses for irrigation. Bib taps offer high flow rates suited to outdoor applications and are typically resistant to harsh weather conditions.

Installation and Maintenance:

Pillar taps and bib taps also differ in their installation and maintenance requirements. Pillar taps are usually installed on sinks or countertops and are integrated into the plumbing system. They require separate hot and cold water supply lines and may require additional components like spouts, handles, and sprayers. Pillar taps are relatively easy to install, and maintenance typically involves replacing worn-out parts like O-rings and washers.

Bib taps are standalone fixtures mounted on exterior walls or structures. They are connected to a single water supply line and do not have additional components. Bib taps are straightforward to install and require minimal maintenance since they have a simple valve mechanism that can be quickly repaired by replacing the washer or valve disc.

Conclusion:

While pillar taps and bib taps share the common function of controlling water flow, they differ in important ways. Pillar taps are designed for indoor applications, while bib taps are for outdoor use. Pillar taps provide precise temperature control and water flow, while bib taps offer high flow rates based on low-pressure systems. Understanding the differences between these two types of taps is essential for selecting the right tap for specific plumbing needs.
