The Importance of Wet Barrel Hydrants in Firefighting
In the United Arab Emirates, and specifically in Dubai, the demand for high-quality fire protection systems is ever-increasing. The UAE is home to numerous power plants, industrial facilities, and urban developments, all of which necessitate efficient and reliable fire protection measures.
Hence, fire hydrants are an integral part of any community’s fire protection infrastructure, ensuring quick access to water in the event of a fire emergency. Among the various types of fire hydrants, wet barrel hydrants are widely used for their efficiency and ease of maintenance.
In this comprehensive guide, we will delve into the installation, maintenance, and operation of wet barrel hydrants, focusing on a specific product supplied by Dutco Tennant LLC – the AVK wet barrel hydrant.
Understanding Wet Barrel Hydrants
Wet barrel hydrants are a fundamental part of municipal water supply systems, specifically designed for fire protection. Unlike dry barrel hydrants, which store water below the frost line and require draining in freezing temperatures, wet barrel hydrants are constantly filled with water. This makes them particularly suitable for regions where freezing is not a concern and quick access to water is essential in emergency situations.
One key feature of wet barrel hydrants is that they are equipped with above-ground control valves. These hydrants have outlets above the ground, making them easily accessible to firefighters for swift connection to hoses. Furthermore, they allow for easy maintenance and repair.

Installation of Wet Barrel Hydrants
Proper installation of wet barrel hydrants is crucial to ensure their functionality and reliability during emergencies. Here are the key steps involved in the installation process:
Site Selection: Choose an appropriate location for the hydrant, considering factors such as proximity to water sources, accessibility for firefighting crews, and compliance with local regulations.
Excavation: Dig a hole to the required depth for the hydrant’s bury depth. Ensure that the hydrant’s inlet pipe is below the frost line if applicable in your region.
Setting the Hydrant: Position the hydrant in the hole and connect it to the water supply line. Make sure all connections are properly sealed to prevent leaks.
Backfilling: Fill the hole with soil, compacting it in layers to provide stability and prevent settling.
Above-Ground Installation: Attach the hydrant outlets and valve stems above ground. Ensure proper labelling of outlets for easy identification during firefighting operations.
Hydrant Painting: Paint the hydrant to make it visible and easily recognizable, typically in a distinctive colour such as red.
Testing: Conduct a thorough pressure and flow test to ensure that the hydrant operates within the specified parameters.
Maintenance and Operation
Maintaining and operating wet barrel hydrants is key to ensuring their reliability during emergencies. The AVK Wet Barrel Hydrant, with its ease of maintenance, simplifies this process. Here are the general steps to maintain and operate a wet barrel hydrant:
- Regular Inspections:
Perform routine inspections to check for any visible damage, leaks, or signs of wear. Look for any obstructions around the hydrant that might hinder access.
- Lubrication:
Apply lubrication to the hydrant’s moving parts to ensure smooth operation. Regular lubrication prevents rust and corrosion and extends the hydrant’s lifespan.
- Hydrant Operation:
Periodically operate the hydrant to ensure it functions correctly. Test each outlet to verify water flow and pressure. Check the valve operation for any signs of stiffness or difficulty.
- Maintenance Schedule:
Follow the manufacturer’s maintenance schedule and guidelines. The AVK Wet Barrel Hydrant’s manual provides specific instructions for maintenance and repair tasks.
- Winterization:
In regions with cold winters, take steps to prevent freezing. This might include draining the hydrant or using insulating covers. The AVK Wet Barrel Hydrant’s design, with water surrounding the main valve, helps prevent freezing in milder cold conditions.
- Emergency Operation:
Ensure that designated personnel know how to operate the hydrant in case of a fire emergency. This includes understanding the hydrant’s location and the operation of the main valve.
