Emergency Well Pressure Tank Replacement in O'Fallon
A sudden loss of water pressure or a completely failed well pressure tank can be an emergency, especially for rural homes around O'Fallon that depend solely on well water.

Our technicians are available to assess the problem and perform the necessary replacement to restore your water supply as soon as possible, preventing prolonged inconvenience and potential damage to your well pump from overworking.
Constant Pressure System Conversion in O'Fallon, MO
A constant pressure system pairs a variable speed drive like the Franklin SubDrive or Grundfos SQE with a smaller pressure tank. The pump speeds up or slows down to hold a set pressure, so showers do not fade when a sprinkler kicks on. These systems cost more, often $2,500 to $5,000, but they end pressure swings. They also reduce hard starts on the motor. We explain whether your well and pump are good candidates.
Tank Tee, Gauge and Relief Valve Replacement in O'Fallon
The tank tee is the manifold that connects the tank, switch, gauge, relief valve and drain. Galvanized tees corrode and restrict flow, especially with sandy or mineral-heavy water. We replace them with brass or stainless steel tank tees that hold up much longer. A new liquid-filled gauge gives accurate readings, and a fresh relief valve protects against a stuck switch. These small parts make a big difference in how well the system holds up.
