Well, its not often I can say this, but what an absolutely fantastic service from Calor. I was certain the smell of gas wasnt from the caravans system as we hadnt been putting gas through it and it was isolated at the bottle. Having put a new bottle in last week, I wondered if it was a fault on the bottle and for advice I rang the Calor emergency number.
They sent out an engineer, who has only just left as I write this at 2119 hrs. Hes been here for a good three hours and he tested properly both bottles, and the whole caravan system. He couldnt find any fault at all and suggested it may be a bit of waxing causing venting within the regulator, and proceeded to change the regulator. As he left, he left me a bottle of fluid for testing the seals around the gas fittings, not sure what it is but its chemical, and not soapy water.
And the charge for this service.....................................zero. A brilliant and friendly service, well pleased. And to top it off, the lad has had a 110 mile journey each way.
