1. Introduction
The YATO YT-24800 Pressure Loss Tester is a robust manual pump designed for precise pressure and leak testing of various closed systems. It is an essential tool for professionals working with sanitary and heating systems, boilers, pressure vessels, and installations involving water, CO, compressed air, or oil. This device is also ideal for filling solar installations or systems with antifreeze agents, ensuring system integrity and preventing costly leaks.
2. Safety Instructions
- Always wear appropriate personal protective equipment (PPE), including safety glasses and gloves, when operating the tester.
- Ensure all connections are secure and leak-free before applying pressure. Loose connections can lead to sudden pressure release and injury.
- Do not exceed the maximum operating pressure of 50 bar (5 MPa). Over-pressurizing systems can cause damage to the system or the tester, and may result in serious injury.
- Never use the tester with flammable or corrosive liquids unless explicitly stated as safe for such use. This tester is designed for water, CO, compressed air, oil, and antifreeze solutions.
- Keep the work area clean and well-lit.
- Do not modify the tester in any way. Use only original YATO spare parts if replacements are needed.
- After testing, always release pressure slowly and carefully.
- Keep out of reach of children.
3. Product Overview
The YATO YT-24800 Pressure Loss Tester is constructed for durability and reliable performance. Key components include a robust steel tank, a high-pressure pump mechanism, and a precise manometer for accurate readings.
Figure 1: YATO YT-24800 Pressure Loss Tester. This image shows the complete unit, highlighting its compact design and key specifications like dimensions (490x160x165 mm), pressure range (0-5 MPa), connection size (G1/2), and tank capacity (12L).
Key Features:
- Durable Construction: The tank is made from solid 2 mm thick sheet steel, powder-coated for enhanced durability. The pump features an aluminum housing, carbon steel components, and a chrome handle.
- Corrosion Resistance: The pump's material is resistant to corrosion inhibitors commonly added to CO systems, ensuring longevity.
- High Pressure Capability: Capable of generating a maximum pressure of 50 bar (5 MPa).
- Generous Tank Capacity: Features a 12-liter tank for sufficient fluid volume during testing or filling operations.
- Efficient Pumping: Suction capacity of approximately 45 ml per stroke.
- Standard Connection: Equipped with an R 1/2" internal thread connection for compatibility with common piping systems.

5. Setup
- Unpack the Tester: Carefully remove the YATO YT-24800 from its packaging and inspect for any signs of damage.
- Prepare the System: Ensure the system to be tested is isolated and drained if necessary. Close all valves and outlets that are not part of the test section.
- Connect the Tester: Connect the tester's hose to the system's designated test point. Ensure the R 1/2" internal thread connection is securely fastened to prevent leaks. Use appropriate sealing tape or compound if required for a watertight seal.
- Fill the Tank: Open the tank lid and fill the 12-liter tank with the appropriate testing fluid (e.g., water, antifreeze solution). Ensure the fluid is clean and free of debris. Do not overfill.
- Bleed Air (if applicable): If testing with liquid, slightly open a valve at the highest point of the system to allow air to escape as the system fills with fluid from the tester. Close the valve once fluid begins to emerge, indicating the system is full of liquid and free of air pockets.
6. Operating Instructions
- Initial Pumping: With the system connected and filled (if using liquid), begin to operate the pump handle. Pump slowly and steadily to build pressure within the system.
- Monitor Pressure: Observe the manometer on the tester. Continue pumping until the desired test pressure is reached. Do not exceed the maximum recommended pressure for the system being tested or the tester's maximum pressure of 50 bar (5 MPa).
- Isolate and Observe: Once the target pressure is achieved, close the valve on the tester's hose to isolate the system from the pump. Observe the manometer reading over a specified period (e.g., 30 minutes, 1 hour, or as per industry standards).
- Identify Leaks: If the pressure drops during the observation period, it indicates a leak in the system. Visually inspect all connections, joints, and components for signs of fluid leakage or listen for hissing sounds if testing with air. A leak detection spray can be used for air tests.
- Release Pressure: After the test is complete, or if a leak is detected, slowly open the pressure release valve on the tester or a designated valve on the system to safely depressurize.
- Disconnect: Once the pressure has returned to zero, disconnect the tester from the system.
7. Maintenance
- Cleaning: After each use, especially when using different fluids, thoroughly rinse the tank and pump mechanism with clean water to prevent residue buildup and corrosion.
- Storage: Store the tester in a clean, dry place, away from direct sunlight and extreme temperatures. Ensure the tank is empty before storage.
- Hose and Connections: Regularly inspect the hose for cracks, wear, or damage. Check all connections for tightness and replace seals or O-rings if they show signs of wear or leakage.
- Manometer Calibration: Periodically check the accuracy of the manometer against a known calibrated gauge. If readings are consistently inaccurate, the manometer may need replacement or professional calibration.
- Lubrication: Apply a small amount of appropriate lubricant to moving parts of the pump mechanism as needed to ensure smooth operation.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No pressure build-up | Loose connections, air in the system, faulty pump seals, clogged intake. | Check all connections for tightness. Bleed air from the system. Inspect and replace pump seals if worn. Clean the intake filter. |
| Pressure drops quickly | Leak in the system or tester connections, faulty non-return valve in pump. | Inspect all system components and tester connections for leaks. Tighten or replace seals. Check the non-return valve for debris or damage. |
| Inaccurate manometer reading | Manometer out of calibration, damaged manometer. | Compare reading with a known accurate gauge. If consistently off, replace or recalibrate the manometer. |
| Pump handle stiff or difficult to operate | Lack of lubrication, internal debris, worn seals. | Lubricate moving parts. Disassemble and clean pump mechanism. Inspect and replace worn seals. |
