LPG Tank

I have a 12 plate Warwick duo and usually refill my tank once a year and have never had any problems nor smell of gas. Might be worth having a dealer looking at the valve

On our 2014 Broadway, we had a leak during the first year, losing a tank full of gas while standing at the front of our house! This was sorted out, under warranty, by AS. When we arrived to have it done, Mark swung underneath and discovered the tank was out of alignment, so that was also sorted at the same time!!

No more problems since, hopefully.

P.S. Our gas leak - it was a loose joint that just needed tightening!

Difficult to offer an opinion on the possible cause from afar, but if it were me I would get it checked fairly quickly.

I think you really need an engineer to be present while you fill the tank, in case there's a leak between the fill point and the entry into the tank. It sounds like it might be there, or presumably you would be losing gas all the time.

Do you have a non return valve in the actual fill point? I believe some do, and if yours is one of those and you have a leak where I suggested, the contents of the hose from fill point to tank could slowly leak out, giving you the smell over a period of a day or two.

It wouldn't need much to give a strong smell, as ethyl mercaptan (the smelly additive in LPG) is one of the strongest and most penetrating pongs around - hence it's use for this purpose.
