Heatrae Sadia Megaflo problem

[magicman]

Hi guys.

Had a dripping through the discharge pipe, visible through the tundish for ages.

Tried recharging the air gap to no avail.

Had the 3 bar sustaining valve and 8 bar PRV valves replaced and it still done it.

Forgot about it for a while, but now its actually running through the tundish. Recharged the air gap yet again today and again - No joy!

The water running through the tundish is cold.

What am I missing?

Cheers

It was doing it before it got replaced. But since then, the (new) 8bar relief has been taken off and cleaned...
