From drain and sewer pipe installations to repairs and replacements, we are the commercial plumbing company to turn to when you need the best commercial drain and sewer services in the DC metro area.

Gas Plumbing Services

At JPG Plumbing & Mechanical, we install and repair natural gas plumbing systems, propane piping, medical gas piping, compressed air lines, and more. We have the experience to ensure a safe, leak-free installation and the equipment to detect leaks in older natural gas or propane lines.

Video Inspections

If the drain or sewer system at your business suffers from frequent clogs, a video camera pipe inspection may be your best diagnostic tool. One of our most popular commercial plumbing services, video inspections allow us to scrutinize the interior of drain or sewer pipes, looking for cracks, breaks, or obstructions like roots that can catch debris and cause clogs. These inspections allow us to determine the best repair options for your drain or sewer pipes.


One of the latest tools in our drain cleaning arsenal, our powerful hydro-jetting systems allow us to use water under extremely high pressure to cut through tough tree roots, grease, paper, sediment, and other debris to leave your drain or sewer lines clean and flowing freely.

Water Softening & Filtration

Could the quality of the water at your facility be improved? Want to provide the best food and beverages for your customers? Improve the taste, smell, and quality of your water with a water-softening system, reverse osmosis system, or pure water system from our commercial plumbing team at JPG Plumbing & Mechanical.
