Megaflow problem !!!

[Systemfix]

Hi guys

ive got a nagging problem, I noticed that water was continually pouring outside the building out of the overflow and was continuous so what I did is turned off the hot flow to my taps from the gate valve on the megaflow tank and it stops but then when you open it again it pours outside again, what could this be as its really annoying,

thanks guys

Firstly follow instructions on side of megaflo, or in the book on how to restore air gap in the megaflo.

If this doesn't work you will need a G3 registered plumber to probably replace the TPR valve.

Thanks Dave your a star,

Turn off supply to tank,drain it right down,then fill it up again.

The instructions on how to do this are usually on the side of the tank for owners to remake air bubble. This is how i remember them being written:

1. Turn off cold main to tank
2. Open up relief valve on side of tank and hot tap
3. Allow water to flow and keep open until gurgling stops.
4. Close relief valve with a snap and turn off taps again.
5. Turn back on cold main and allow to refill

This should remake air bubble. If the relief valve continues to drip then an unvented qualified engineer will need to replace it.

Thanks for that but the overflow leaks on the outside of the building and not from the relief vave ( black trianglar valve with a hole in it to see if it drips), is this the same overflow?
thanks again

They should be the same pipe. If there isnt water flowing through the tundish then its not the megaflo.
