Twice a year we do change the hose to our gas tank that connects to our stove. This is to make sure of the safety at home. We have heard lots of fire cases concerns the leakage from the gas tank hose. Fire is so scary that is why we regularly change the hose to avoid and prevent fire problem. The problem is that sometimes we bought the kind of hose that is not of good quality. Instead of buying twice a year, we end up buying more than twice. Buying more than twice is pain in the pocket especially today that the prices are going up. We are looking for a good quality of hose like the titeflex teflon hose to replace the old one. I have read some reviews and based from what I have read this one is a good choice.
