Boilers, gas and lots of rain :)

Got a mate who works for southern electric and he was telling me today how he went out to a boiler that weren't working.

When he got there he finds out that the condense had been fitted to the rainwater pipe and with all the rain we've had, it managed to back fill up the condense and flood the boiler.

If you think that's bad, the water also managed to get back down the gas valve, fill the gas pipe to the boiler, worked it's way all the back to the metre and flooded the metre aswell

I think its safe to say I won't be connecting one to the rain water anytime soon

could be a good idea for us to fit drainoffs on gas pipes from now on then? considering the weather we are getting at the moment, just slap one of these on them from now on!! haha

I always put an air gap between the 22 - 32 upsize outside. Then this can never happen because any backflow will just spill over from the air gap.

You aren't meant to connect into rainwater pipes without an air gap for this very reason.
