Now what in the world is that gon na do ? I did n't know what the problem was , but I could n't see how a new tank valve was going to fix the thing . I threw the valve back in the box put it back under the BBQ , until today . After getting back and finding that gas was n't getting to the BBQ , I pulled the valve out from the box and figured I did n't have anything to lose by trying the new valve .
According to the above context, answer the following question.
What may have been the reason for them putting the valve under the BBQ ?


They may not have felt confident enough that they could fix it themselves .
