Help! ,megaflow recharge overflow will not stop flowing

[TWright]

Hi

Carried out the recommended steps for the annual service and now the expansion relief valve has been flowing non-stop!

Can't work out why this would be.
Followed the instructions to a tee opened the pressure relief valve as per instructed for about 20 mins while the tank drained.

Now the wife is doing her nut!

Anybody help ???

try opening and closing the exp relief valve a few times, it may stop, or at least minimise, the flow. you need a certificated engineer to do any work on a megaflow.
