Introduction
This manual provides comprehensive instructions for the installation, operation, and maintenance of your LZMZMQ Water Pressure Tank. Designed for various applications including household, school, livestock, industrial, and agricultural use, this tank helps stabilize water pressure and ensures a consistent water supply.
The LZMZMQ Water Pressure Tank is constructed from food-grade PE material, featuring a 1.5cm thick wall for high toughness, pressure resistance, and freeze protection down to -60°C. It is designed to be directly contacted with water, meeting standards for human consumption.
Key features include:
- Eco-friendly PE Material: Safe, odorless, and freeze-resistant.
- Automatic Operation: Works with a water pump (not included) to automatically maintain water pressure.
- Safety Valves: Equipped with a safety valve and a negative pressure integrated valve for automatic exhaust and drainage, preventing overpressure and vacuum formation.
- High Load Capacity: Capable of supporting up to 300kg (660lbs).
- Versatile Applications: Suitable for well systems, solar water heaters, washing machines, and various water supply needs.

Setup and Installation
Proper installation is crucial for the optimal performance and longevity of your water pressure tank. This tank is designed for easy installation and can be placed near a well, in a yard, stairwell, toilet, or kitchen.
Installation Steps:
- Positioning: Select a suitable location for the pressure tank. Ensure it is on a stable, level surface. The three bottom support legs are designed to prevent tipping.
- Water Pump Connection: The pressure tank must be connected to a water pump (not included). The pump should be installed at the inlet of the pressure tank.
- Water Inlet Connection: Connect the water source to the water inlet pipe of the pressure tank. Ensure all connections are secure and watertight.
- Water Outlet Connection: Connect the water outlet pipe from the pressure tank to your household or irrigation system.
- Drain Outlet Connection: Connect a drain pipe to the drain outlet (20mm/0.8in inner diameter) for maintenance and system flushing.
- Check Valve Installation: An all-copper check valve must be installed in the system to prevent backflow.
- Pressure Switches and Gauges: Ensure pressure switches and pressure gauges are correctly installed and functional for monitoring and controlling water pressure.
- Initial Fill and Pressure Check: After all connections are made, slowly fill the tank with water and check for any leaks. Monitor the pressure gauge as the tank fills.

Operating Instructions
The LZMZMQ Water Pressure Tank operates automatically in conjunction with a water pump to maintain consistent water pressure.
Working Principle:
- The water pump fills the pressure tank with water. As water enters, the air inside the tank is compressed, generating air pressure.
- When the air pressure within the tank reaches a preset value (approximately 0.28Mpa), the pressure controller signals the water pump to turn off, stopping the water intake.
- When water is drawn from the system, the water volume in the tank decreases, causing the air pressure to drop.
- Once the pressure drops to a lower set value (approximately 0.14Mpa), the controller activates the water pump again to replenish the tank and restore pressure.
- This automatic cycle ensures a continuous and stable water supply, even during power outages, for a short duration.
Note: Due to the compressed air above the water, the actual water storage capacity of the tank is approximately 50% to 70% of its stated volume, depending on the pressure settings. Higher pressure settings generally result in more stored water.
Maintenance
Regular maintenance ensures the longevity and efficient operation of your LZMZMQ Water Pressure Tank.
- Regular Inspection: Periodically check all connections for leaks. Tighten any loose fittings.
- Pressure Monitoring: Regularly observe the pressure gauge to ensure the system is operating within the desired pressure range.
- Drainage: Utilize the drain outlet to periodically flush the tank, removing any accumulated sediment. This helps maintain water quality and system efficiency.
- Valve Check: Ensure the safety valve and negative pressure integrated valve are free from obstructions and functioning correctly.
- Cleanliness: Keep the exterior of the tank clean. While the PE material is durable, regular cleaning can prevent buildup.
- Freeze Protection: Although the tank is freeze-resistant, in extremely cold climates, ensure the installation area is adequately protected to prevent freezing of connected pipes and components.
Troubleshooting
This section addresses common issues you might encounter with your water pressure tank.
| Problem | Possible Cause | Solution |
|---|---|---|
| Frequent Pump Cycling | Low air charge in the tank, small leak in the system, or incorrect pressure switch settings. | Check for leaks and repair. Verify pressure switch settings. Consult a professional if the issue persists. |
| Unstable Water Pressure | Insufficient air pressure in the tank, faulty pressure switch, or sediment buildup. | Check tank air pressure. Inspect and clean the pressure switch. Drain and flush the tank. |
| No Water Flow | Water pump failure, power outage, or clogged pipes. | Check power supply to the pump. Inspect pump for operation. Check for pipe blockages. |
| Water Leakage | Loose connections, damaged pipes, or faulty valves. | Inspect all connections and tighten as necessary. Replace damaged pipes or valves. |
| Tank Not Holding Pressure | Internal bladder issue or persistent system leak. | Inspect for external leaks. If no external leaks are found, internal inspection by a professional may be required. |
