Water pressure booster pumps for Knoxville homes with weak supply

Booster Pump Sizing

A booster pump is sized to two numbers: how much pressure the house needs to gain, and how much water flows at peak, with several fixtures running at once. Undersized, it can't keep up with a shower and a washer together; oversized, it short-cycles and wears out early. We measure static and flowing pressure at the supply, count the fixtures, and pick a variable-speed or fixed-speed pump to match. Variable-speed pumps hold steady pressure as demand changes and run quieter, which suits most homes.

Booster With Pressure Tank

A small pressure tank beside the booster stores pressurized water so the pump does not start every time a faucet opens for a glass of water. That cuts the number of starts, extends the pump's life and smooths out pressure at the tap. The tank's air charge is set to match the pump's cut-in pressure. We install it with isolation valves, add a bypass so the house still gets water if the pump is off for service, and fit a check valve so boosted water cannot push back toward the street.

Whole-House or Single-Fixture Boost

A whole-house booster sits on the main line after the shutoff and raises pressure everywhere. A smaller point-of-use booster serves one problem fixture, such as an upstairs shower at the far end of the house. The whole-house option costs more but solves the problem everywhere at once; the single-fixture option costs less when only one spot suffers. We tell you which the measurements support, and whether the house would be better served by fixing the pipe than by boosting the pressure.
