Sometimes, after a long time of being in service, your LP (Liquefied Petroleum) hose can start to leak. Sometimes the joint can also be fit loosely and leak. Once a year, you should make sure to have your LP hose carefully checked by a professional. In the mean time, you can buy the tools (leak detector solution) yourself to check in the mean time. You want to make sure there are never any leaks with your propane, because that could lead to an explosion around an open flame. Make sure to not light any pilot or burners when checking. If you do find a leak, make sure to get it repaired or replaced as soon as possible.
