Atmospheric Vent Tank Upgrades in Mount Pleasant, SC
Most older homes have atmospheric vent water heaters that rely on natural draft up a metal flue. We inspect the flue pipe for rust, proper slope and correct connector size during replacement. A loose or undersized vent can leak exhaust into the garage or closet. We replace damaged vent sections and draft hoods as needed. Then we test draft with the burner running before we leave.

40 and 50 Gallon Tank Replacement in Mount Pleasant
The 40 and 50 gallon gas tank is the workhorse of most South Carolina homes. When yours starts leaking from the bottom seam or produces rusty water, replacement is the only true fix. We match the new tank's height and diameter to your space and reuse the venting when it is in good shape. Newer tanks are sometimes taller due to efficiency standards, so we check clearance before ordering. Most of these jobs take about two to three hours.
Thermal Expansion Tank Installation in Mount Pleasant
Many water utilities install pressure regulators or backflow devices that create a closed system. When water heats and expands, pressure spikes can strain your tank and fixtures. Code commonly requires a thermal expansion tank on these systems. We install a correctly sized expansion tank and pre-charge it to match your water pressure. This simple add-on can help your new heater last longer.
