Let your customers know you’re following all code recommendations and guidelines, such as keeping propane tanks away from combustible materials and protecting propane systems from vehicles. If it makes sense for your project, installing the propane tank underground minimizes exposure to weather-related issues, although they should still be strapped down in flood-prone areas. Most importantly, leave installation and repair work to the professionals. Tell your customers that trying to save money with a DIY project just isn’t worth the risk.
