Occasionally, water bells become obstructed with mud and debris, preventing them from working correctly. If you notice your water bell is not working properly, you may need to clean it.

Here’s a the guide on how to clean a water bell for fire sprinklers:

Step 01. Turn Off the Sprinkler System’s Water Supply

The process for turning off the water supply will vary depending on your system type, but there are a few general steps you can follow:

  • Locate the main water shut-off valve for the sprinkler system. This is usually located near the fire pump or in the basement near the water meter.
  • Turn off the supply to the pump. This will ensure no water flows through the system while working on it.
  • Open each sprinkler valve and allow any remaining water to drain out. Once the valves are all open, you can close the main shut-off valve and begin your cleaning process.

Step 02. Disconnect the Water Supply Line

The fire sprinkler head should be disconnected from the water supply line once all remaining water has been drained. Unexpected water pressure could cause severe damage to the sprinkler head.

Find the connection point between the supply line and the sprinkler head. This is usually located behind the head. Loosen the nut that secures the supply line to the head using a wrench. Once the nut is loosened, you should be able to pull the supply line away from the head.

Step 03. Remove the Water Bell from the Sprinkler System

Start by unscrewing the attaching screw with a screwdriver to remove the water bell. Once the screw has been removed, it should be possible to pull the water bell away from the sprinkler.

If the bell is stuck, you may need to use a pair of pliers to help remove it. Once removed, you can clean it with a brush or cloth before reattaching it.

Step 04. Remove All the Water from the Bell

The next step is to remove any remaining water from the bell. To do this, you will need to turn it upside down, open the drain valve, and allow the water to drain from the bell. Once all the water has been exhausted, the bell can be cleaned with a mild detergent and then rinsed with clean water.

Step 05. Brush Out Any Debris or Sediment Inside the Bell

The water inside the sprinkler’s bell can become filled with debris or sediment. If this happens, it could clog the sprinkler and interfere with its operation during a fire. There is a simple way to clean out any debris or sediment accumulated inside the bell.

Remove the bell from the rest of the fire sprinkler. Then, using a brush, scrub away any loose sediment or debris that you see inside the bell. Rinse the bell with clean water to remove any residual dirt or grime.

Step 06. Clean the Bell Inside and Outside

When cleaning the bell, all internals need to be cleaned. This includes the valve, piston, and seat. To clean the internals, disassemble the bell and soak all parts in a bucket of soapy water. Then, use a soft brush to scrub any remaining dirt or debris.

Ultimately, rinse the parts with clean water. Having rinsed the bell, a clean cloth should be used to dry the inside and outside of the bell.

Step 07. Reattach the Water Bell and Turn on the Water Supply

To reattach the water bell, simply screw it back into place. Once it is secure, you can turn on the water by opening the valve at the unit’s base. When finished, close the valve and replace any removed covers during the cleaning process.

Following these steps should allow you to clean your water bell and keep your fire sprinkler system in good working order. Regular cleaning and maintenance will help ensure your system works correctly during an emergency.

What are the Purposes of Using a Fire Sprinkler Water Bell?

A key component of a fire sprinkler system is the water bell. This device is installed at the end of the main water supply line and helps to maintain pressure in the system. Here are some reasons for using a water bell with a fire sprinkler:

  • Can prevent water contamination by using a check valve or backflow preventer.
  • The control valve shuts off water flow to sprinklers, hoses, or hose connections for inspections, tests, and maintenance.
  • A pressure gauge is used to determine the integrity of a piping system.
  • In testing and repairing, a drain valve is used.
  • The movement of water triggers the sound of water flow alarms through pipes.

These are some reasons why fire sprinklers and water bells are used. Keeping these devices in good working order can help ensure that your fire sprinkler system will keep you safe from fires.

How Does a Fire Sprinkler Water Motor Gong Alarm Bell Work?

How Does a Fire Sprinkler Water Motor Gong Alarm Bell Work

In its most basic form, a water motor gong can be described as a large, wall-mounted bell secured with a guard. In conjunction with fire alarm checks, dry pipes, deluge valves, and preaction valves, these alarms are typically mounted on the outside walls of fire riser rooms.

Water motor gongs are required for wet sprinkler systems, but other automatic sprinkler systems can use existing valves. When the sprinkler system is activated, water flows through the piping and into the water motor gong bell.

The increase in water pressure turns the turbine inside the gong, which sets off the fire alarm. Water motor gong bells are designed to be loud so they can be heard above the noise of a fire. They are also big enough to be seen from a distance, making them an effective way to warn people of a fire.

Do Fire Sprinklers Go Off If You Clean a Water Bell?

Water bells are often used with fire sprinklers but are two separate devices. Water bells are connected to the building’s water supply and are used to provide a constant flow of water to the sprinkler system. This water flow helps keep the sprinkler system clean and clear of debris. So, it is unlikely that cleaning a water bell would shut off a fire sprinkler.

Most modern fire sprinklers are designed only to activate when they sense high heat. Simply cleaning a water bell should not be enough to set them off. But, it is possible to accidentally trigger a fire sprinkler if you use high-pressure water through the water bell.

So, if you’re cleaning a water bell near a fire sprinkler, it’s essential to be careful with the water pressure. If you’re unsure, it’s always best to consult a professional before beginning any work on a fire sprinkler system.
