To add pressure to your expansion tank, first, turn off your boiler and allow the system to cool. Next, locate the Schrader valve on the tank (it looks like a bike tire valve). Check the current pressure with a tire pressure gauge. The desired pressure is typically around 12-15 psi, but refer to your system's specifications. If low, use a bicycle pump or air compressor to add air until you reach the correct psi. Be cautious not to overpressurize, as this can damage your system.
FAQs & Answers
- What is an expansion tank and why is it important? An expansion tank is a crucial component of a heating system that helps manage pressure changes as water heats up and expands. It prevents damage to the system by allowing excess pressure to be absorbed, ensuring efficient operation.
- How do I know if my expansion tank needs more pressure? To check if your expansion tank needs more pressure, use a tire pressure gauge to measure the pressure at the Schrader valve. If it’s below the recommended level (typically 12-15 psi), it’s time to add air.
- What tools do I need to add pressure to my expansion tank? You'll need a tire pressure gauge to measure the existing pressure, and either a bicycle pump or an air compressor to add air to the expansion tank.
- Can I overinflate my expansion tank? Yes, overinflating your expansion tank can damage the system. It's important to adhere to the recommended pressure range specified by your heating system's manufacturer.
