How To Properly Repair A Water-based Fire Extinguisher?

As a common home fire extinguisher, water-based fire extinguishers may have some failures when used. The following are several common faults and solutions.
1. The jet cannot be sprayed properly
This condition is usually caused by a clogged nozzle. The solution is to invert the fire extinguisher 10-15 times to release the pressure, then unscrew the fire extinguisher and take out the nozzle for cleaning. Be sure to use clean water, do not use chemical solvents.
2. The pressure is too low
When the pressure of the fire extinguisher is too low, it cannot be used normally. The solution is to inflate according to the fire extinguisher instructions. If the self-inflating fails, it is recommended to send it to a professional repair site for processing.
3. Too much stress
This condition may be caused by excessive storage time. The solution is to turn the pressure relief valve open to release some gas, reduce the pressure, and then use it normally.

If the above methods cannot solve the problem, or the fire extinguisher has a more serious fault, more in-depth maintenance is needed. The following details the maintenance process of water-based fire extinguishers.
Step 1 Disassemble
First of all, you need to disassemble the fire extinguisher and separate the inner tank from the housing. Attention should be paid to safety during disassembly to prevent the danger caused by hydraulic release.
2. Clean and replace the parts
After the disassembly is complete, you need to clean and check the internal components. The main thing that needs to be cleaned is the nozzle and the agent tank, which need to be thoroughly cleaned with detergent. The old nozzle needs to be replaced.
Step 3 Assemble
After cleaning and replacement, the components need to be reassembled in their original positions. Note the installation sequence and correctness.
Step 4 Inflate
Inflate according to fire extinguisher instructions.
Step 5 Check
After the completion of inflation, the fire extinguisher needs to be tested to ensure that its performance meets the standard.

Keeping the water based fire extinguisher in good condition can extend its service life and improve its use effect. Here are some maintenance precautions:
1. Check once a month to ensure normal pressure; A full inspection is required within a year
2. Clean the fire extinguisher regularly, and clean it more frequently when it is used in dust, corrosion and other environments
3. Do not place the fire extinguisher in the heat source, direct sunlight and other environments
4. Use clean water when cleaning, do not use chemical solvents
5. Do not disassemble or replace internal parts without permission

This article hopes to help readers better understand the maintenance methods and maintenance precautions of water-based fire extinguishers. In daily use, we must pay attention to safety and ensure the effect of use.
