A base model Weber will need new grates and flavorizer bars in about five years if the grill is used regularly but kept up; in about three years if neglected. The burners will usually last between five and ten years. They are worth replacing at least once.
Vacuum sealing does exactly what its name implies – seals the contents of a plastic bag through a vacuum. After placing your food in a sealable bag, a vacuum sealer removes the air and leaves the item intact for long-term storage. The vacuum created by the sealer prevents any compounds from permeating the bag.
