Common troubleshooting of pure water machine equipment: solutions for substandard water production, water leakage, and abnormal pressure
Date: 2025-10-23Read: 1
Pure water machines may encounter various malfunctions during use, which can affect the normal operation of the equipment and the quality of the produced water. This article will provide a detailed introduction to the troubleshooting methods for common faults in pure water machines, including substandard water production, water leakage, and abnormal pressure. Through these methods, you can quickly locate the problem and take corresponding solutions to ensure the stable operation of the equipment.
1、 Non compliant water production: Investigation and solution of water quality problems
One of the common faults of pure water machines is that the produced water does not meet the standards, usually manifested as water quality indicators (such as conductivity, pH value, microbial content, etc.) not meeting the requirements. Here are some troubleshooting and solutions:
Check the pre-processing system
The main function of pre-treatment systems (such as PP filters and activated carbon filters) is to remove large particulate impurities and organic matter from water. If the pre-treatment filter element expires or becomes clogged, it may lead to a decrease in water quality. It is recommended to replace the pre-treatment filter regularly, usually every 3-6 months.
Check if the pre-treatment filter element is installed correctly to ensure smooth water flow. If the filter element is not installed properly, it may cause some water flow to bypass the filter element, affecting the filtration effect.
Check the reverse osmosis membrane
Reverse osmosis membrane is the core component of a pure water machine, responsible for removing dissolved solids and microorganisms from water. If the reverse osmosis membrane is contaminated or damaged, it may cause an increase in the conductivity of the produced water. It is recommended to regularly check the performance of the reverse osmosis membrane and clean or replace it if necessary.
Check the inlet water quality of the reverse osmosis membrane to ensure that it meets the requirements. If the incoming water quality is poor, it is recommended to add pre-treatment equipment such as softeners or filters.
Check ion exchange resin
Ion exchange resin is used to remove ion impurities from water and improve the purity of the produced water. If the resin fails, it may lead to an increase in the conductivity of the produced water. It is recommended to regularly regenerate or replace the ion exchange resin.
Check if the regeneration cycle of the resin is reasonable to ensure timely regeneration before failure.
Check the water quality monitoring system
The water quality monitoring system (such as conductivity meter, pH meter) is used to monitor the quality of the produced water in real time. If the monitoring system malfunctions, it may result in inaccurate readings. It is recommended to regularly calibrate water quality monitoring equipment to ensure accurate readings.
Check if the sensors of the monitoring equipment are clean and clean or replace them if necessary.
2、 Leakage: Investigation and Solution of Equipment Sealing Issues
Water leakage is one of the common faults in pure water machines, which not only affects the normal operation of the equipment, but may also lead to equipment damage. Here are some troubleshooting and solutions:
Check the inlet and outlet
Check if the connection between the inlet and outlet is secure, ensuring that there is no looseness or damage. If water leakage is found at the connection, it is recommended to reconnect or replace the seal.
Check if the drainage pipe is blocked and clean it if necessary. Blocked drainage pipes may cause wastewater to flow back, resulting in water leakage.
Check the filter cartridge housing
Check if the sealing of the filter cartridge housing is good and ensure that there is no water leakage. If water leakage is found in the filter housing, it is recommended to reinstall the filter or replace the seal.
Check if the filter element is installed correctly and ensure that it is tightly attached to the housing. If the filter element is not installed properly, it may cause water leakage.
Check pipeline connections
Check if the internal pipeline connections of the equipment are secure and ensure that they are not loose or damaged. If water leakage is found at the pipeline connection, it is recommended to reconnect or replace the seal.
Check the pipeline for cracks or damage, and repair or replace it if necessary.
Check the equipment casing
Check for cracks or damage on the device casing, and repair or replace as necessary. Damage to the equipment casing may cause internal components to become damp, affecting the normal operation of the equipment.
3、 Abnormal Pressure: Investigation and Solution of System Pressure Issues
Abnormal pressure is one of the common faults of pure water machines, usually manifested as system pressure being too high or too low. Here are some troubleshooting and solutions:
Check the inlet pressure
Check if the inlet pressure meets the requirements of the equipment. If the inlet pressure is too low, it may lead to insufficient system pressure; If the inlet pressure is too high, it may damage the equipment. It is recommended to install a stabilizing pump or pressure reducing valve to ensure stable inlet pressure.
Check if the inlet valve is open to ensure smooth water flow. If the inlet valve is not opened, it may cause insufficient system pressure.
Check the pressure gauge
Check if the pressure gauge reading is accurate and calibrate or replace it if necessary. If the pressure gauge reading is inaccurate, it may lead to misjudging the system pressure.
Check if the installation position of the pressure gauge is correct to ensure that it can accurately reflect the system pressure.
Check the reverse osmosis membrane
Check if the reverse osmosis membrane is blocked or damaged. If the reverse osmosis membrane is blocked, it may cause an increase in system pressure; If the reverse osmosis membrane is damaged, it may lead to insufficient system pressure. It is recommended to regularly clean or replace the reverse osmosis membrane.
Check the inlet water quality of the reverse osmosis membrane to ensure that it meets the requirements. If the incoming water quality is poor, it may cause blockage of the reverse osmosis membrane.
Check the booster pump
Check if the booster pump is operating normally and ensure that the motor and impeller of the pump are not damaged. If the booster pump operates abnormally, it may cause insufficient system pressure.
Check if the inlet and outlet of the booster pump are unobstructed to avoid blockage. If the inlet or outlet of the booster pump is blocked, it may cause abnormal system pressure.
4、 Conclusion
Pure water machine manufacturers may encounter various malfunctions during use, but through correct troubleshooting and solutions, the problem can be quickly identified and corresponding measures can be taken. Non compliant water production, leakage, and abnormal pressure are common types of malfunctions in pure water machines. By inspecting key components such as the pre-treatment system, reverse osmosis membrane, ion exchange resin, water quality monitoring system, inlet and outlet, filter housing, pipeline connections, and equipment housing, these problems can be effectively solved. I hope the troubleshooting methods in this article can help you better maintain the pure water machine, ensure the stable operation of the equipment and the quality of the produced water.
