5. ස්ථාපනය
Proper installation is crucial for the effective operation of your expansion tank. It is recommended to install the tank on the cold water supply line to the water heater.
පූර්ව ස්ථාපන චෙක්පත්:
- Determine System Pressure: Before installation, measure your domestic water system's static pressure using a pressure gauge.
- Pre-Charge the Tank: The expansion tank comes pre-charged from the factory. However, it is essential to adjust the tank's air pressure to match your system's static water pressure. Use an air pump and a pressure gauge (similar to a tire gauge) on the Schrader valve located at the bottom of the tank. This adjustment must be done BEFORE connecting the tank to the plumbing system.
ස්ථාපන පියවර:
- Turn off the main water supply to your home and the water heater.
- Drain a small amount of water from a hot water faucet to relieve pressure in the system.
- Locate a suitable position on the cold water supply line to the water heater. The tank can be installed vertically or horizontally, but vertical installation with the air valve facing down is often preferred for drainage.
- Install a tee fitting into the cold water supply line.
- Apply PTFE (Teflon) tape or pipe thread sealant to the threads of the expansion tank's connection.
- Thread the expansion tank onto the tee fitting. Hand-tighten, then use a wrench to tighten an additional 1 to 2 turns. Do not overtighten.
- Slowly turn the main water supply back on and check for leaks at all connections.

6. මෙහෙයුම
Once installed, the Watts DET-12-M1 expansion tank operates passively. As water in your hot water heater heats up, it expands. This expanded water volume is directed into the expansion tank, compressing the air cushion within the tank's diaphragm. When hot water is drawn from the system, the pressure drops, and the compressed air pushes the water back into the plumbing system. This continuous cycle prevents excessive pressure buildup and protects your water heater and fixtures.
7. නඩත්තු කිරීම
Regular maintenance ensures optimal performance and extends the life of your expansion tank.
- Annual Pressure Check: At least once a year, check the air pressure in the expansion tank. Turn off the water supply to the tank and drain the system pressure before checking the air valve. Adjust the pressure to match your system's static water pressure if necessary.
- කාන්දුවීම් සඳහා පරීක්ෂා කරන්න: Periodically inspect the tank and connections for any signs of water leaks.
- Diaphragm Integrity Check: If water comes out of the air valve when depressed, it indicates that the internal diaphragm has failed, and the tank needs to be replaced.
8. දෝශ නිරාකරණය
This section addresses common issues you might encounter with your expansion tank.
| ගැටලුව | විය හැකි හේතුව | විසඳුම |
|---|---|---|
| Pressure relief valve on water heater frequently discharges water. | Expansion tank is undersized, improperly charged, or has a failed diaphragm. | Check tank's air pressure and adjust if necessary. If water comes from air valve, replace tank. Ensure tank size is appropriate for water heater capacity. |
| High water pressure spikes in the hot water system. | Expansion tank is not functioning correctly (e.g., low air charge, failed diaphragm). | Verify and adjust the tank's air pre-charge. If the diaphragm is compromised, replace the tank. |
| Water leaks from the expansion tank's air valve. | Internal diaphragm has failed. | The expansion tank must be replaced. |
| Tank feels heavy and full of water. | Air charge is lost, or diaphragm has failed, allowing water to fill the air chamber. | Check air pressure. If no air can be added or water comes out, replace the tank. |
