Why does the upstairs shower fade every time the dishwasher starts, and which Franklin Electric booster pump fixes it? The answer depends on what your system is short of: pressure, flow, or control. Use this page to find the right Franklin family in a minute, then follow the link to the models.
Choose a Franklin Electric Booster Pump by the Job
Franklin splits its pressure products into two families. Horizontal multistage booster pumps add pressure to water you already have, and the Inline Controls package changes how an existing pump starts and stops. Match your situation below, then read the family section for the details.
| Your situation | Franklin family | Starting point |
|---|---|---|
| Weak pressure on upper floors or at far fixtures | Horizontal multistage booster | BT4 5 to 25 GPM or MH 15 GPM |
| Reverse osmosis feed or a long supply line that needs high pressure | Horizontal multistage booster | BT4, up to 400 psi |
| Hot water recirculation | Horizontal multistage booster | MH 15 to 45 GPM, rated to 225 degrees F |
| Storage tank set below the pump | Horizontal multistage booster | MH 15 to 45 GPM, suction lift to 10 feet |
| Apartment or commercial building with high demand | Horizontal multistage booster | MH 70 or 90 GPM, three-phase |
| Good pump, but it cycles and the pressure swings | Booster pump package | Inline Controls, pumps up to 3 HP and 20 amps |
| Worn bladder tank you would rather remove | Booster pump package | Inline Controls |
Horizontal Multistage Booster Pumps: BT4 and MH Series
What they are: compact pumps that stack several stainless steel stages on one shaft. Each stage adds pressure, so a small pump can deliver far more pressure than a single-stage unit.
Who they are for: homes on low city pressure, buildings with weak upper floors, RO systems, irrigation, and process water.
Standout specs: the BT4 reaches 400 psi discharge from 5 to 45 GPM. The MH moves up to 90 GPM on motors up to 7.5 HP and handles water up to 225 degrees F. Both carry NSF/ANSI/CAN 372 drinking water certification.

Booster Pump Packages: Inline Controls Pressure Boosting System
What it is: a flow-sensing control that installs in the discharge line and runs your existing pump. It starts the pump when a tap opens and stops it when flow ends.
Who it is for: owners of submersible, jet, or surface pumps up to 3 HP and 20 amps who want steady pressure without a large bladder tank and pressure switch.
Standout specs: run-dry protection on every model, plus daily motor rotation and automatic restart after a fault on the FIL-CTL20. Model details sit on the Inline Controls package page.

- Current pump: the model number from its label, if you have one
- Incoming pressure: a gauge reading at the supply side
- Target pressure: what you want at the highest or farthest fixture
- Peak flow: how many fixtures or zones run at once
- Power: single-phase or three-phase, and the voltage
- Water: hot or cold, and city, well, or storage tank supply
Price follows the job. A 3 HP BT4 costs more than a 1/2 HP model, and adding Inline Controls to a pump you already own usually costs less than a new pump. If you are unsure a booster is the right tool at all, read how booster pumps differ from standard water pumps first.
Frequently Asked Questions
What are the downsides of using a water booster pump?
The downsides of using a water booster pump are added power use, some motor noise, and one more part to maintain. A booster also cannot create water, so it will not help a weak well or a low storage tank. It can stress old pipes and fixtures if you set the pressure too high. Correct sizing, a pressure relief valve, and a control that stops the pump when no water is flowing, such as run-dry protection, address each of these.
Will a booster pump increase water pressure?
Yes, a booster pump will increase water pressure when the supply has enough water but not enough force. It takes the incoming pressure and adds more through each impeller stage. A Franklin BT4 can reach 400 psi discharge, while the MH Series tops out at 140 psi with much higher flow. A booster will not help if the low pressure comes from a clogged filter, a failing regulator, or a well that runs short of water.
Should a booster pump run all the time?
No, a booster pump should not run all the time in a home or small building. It should start when water is drawn and stop when the demand ends. A pump that never shuts off often has a leak, a wrong pressure setting, or a failed switch. Franklin's Inline Controls system uses flow sensing to start and stop the pump, and its run-dry protection shuts the pump down if the water supply is lost.
What is the life span of a booster pump?
The life span of a booster pump depends mostly on how often it starts, whether it ever runs dry, and the water it moves. Stainless steel pumps like the BT4 and MH resist corrosion, and keeping the mechanical seal wet is the biggest single factor in how long they last. Short cycling wears motors quickly, so a proper pressure tank or flow control helps. A quick seasonal check for leaks and frequent cycling catches problems early.
