Quick Answer
A drainback system typically requires annual maintenance, with a more thorough service every 3-5 years, to ensure optimal performance and longevity.
Recommended Maintenance Schedule
Regular maintenance is crucial for a drainback system to function efficiently and prevent potential issues. We recommend checking and maintaining the system annually, with more extensive work every 3-5 years. Annual checks should include inspecting the system for any signs of leaks, ensuring proper valve operation, and verifying the system’s ability to drain and refill correctly.
Draining and Refilling the System
To perform a thorough service, start by draining the system completely, allowing any debris or sediment to be removed. This should be done every 3-5 years, or more frequently if you live in an area with high water hardness or sediment levels. Use a submersible pump to drain the system, and flush the pipes with clean water to remove any sediment or debris. Once drained, refill the system with fresh water and check for leaks.
Valve and Sensor Maintenance
In addition to draining and refilling, it’s essential to inspect and maintain the system’s valves and sensors. Check the solenoid valves for any signs of wear or corrosion, and replace them if necessary. Also, inspect the temperature sensors and thermometers to ensure they are functioning correctly and providing accurate readings. Replace any faulty sensors to maintain the system’s efficiency and accuracy.
