Is there any maintenance that I need to do on my cylinder?

Most of our cylinders are fitted with an internal expansion system.

This removes the need for a separate expansion vessel to handle the extra volume that is caused by heated water expanding, saving you space and making the installation neater.

From time to time you may need to recharge the air gap to make sure it can safely handle the expansion. This is done by following these straightforward steps: 

• Turn off the mains cold water supply to the Megaflo cylinder
• Open the lowest hot tap in the property e.g. in the kitchen
• Hold open the temperature / pressure relief valve until the gurgling noise stops and water stops running from the tap and valve
• Close the temperature / pressure relief valve. Slowly open the mains cold water supply to the Megaflo. When water flows from the hot tap, close the tap
• If water continues to drop or flow from the overflow, then there is an issue that needs attention. Switch off heat sources such as immersion heaters and boilers, but DO NOT turn off the water supply
• Contact your installer for advice
