How do I regenerate the airgap on my Megaflo?

To re-charge the airgap please use the following simple instructions:

  1. Turn off the mains cold water supply to the Megaflo
  2. Open the lowest hot tap in the property
  3. Hold open the temperature / pressure relief valve until the gurgling noise stops and water stops running from the tap and valve
  4. Close the temperature / pressure relief valve; open the mains cold water supply to the Megaflo.  When water flows from the hot tap close the tap
  5. If water continues to drip or flow from the overflow the Megaflo requires attention.  Switch off heat sources (immersion heaters and boiler), DO NOT turn off water supply.  Contact a competent installer for advice.

Watch a heateam video that demonstrates the airgap regeneration procedure.

Can I fit plastic pipework to a Megaflo?

Yes you can providing the pipework is suitably rated to the application.

Do you suggest using a water softener for a Megaflo?

You can use a water softener with a Megaflo if you so wish but this must not be detrimental to the incoming flow rate, and the softened water must not exceed a chloride value of 250 mg/litre.

Can I install a Megaflo in the basement?

A Megaflo can be sited anywhere in your property but the installation of the discharge pipework has to be taken in to account when deciding on where to install the unit.
