Constant Water Pressure Systems
by Little Giant / Franklin Electric

Tired of waiting for that load of clothes in the washer to finish or the sprinklers to turn off before you can take a shower? These constant water pressure systems are the solution to your low water pressure problem! Increasing the flow when demand requires it can make completing everyday projects less taxing, and ease the stresses associated with lack of water pressure.

VERSABOOST PRO Constant Water Pressure System

Traditional municipal systems use city water lines to deliver water to your home. Water pressure may vary for homes due to a number of factors. Some of the more common causes of low water pressure are: old infrastructure, being located a long distance from the main water line or even being at the top of a hill. Fluctuating water pressure and flow can disrupt your daily life and make simple chores around the house difficult. These inline constant water pressure systems are installed on your main water line and connect to a pressure tank that feeds your whole house. As water demand picks up, the encapsulated 4" submersible pump will pump faster keeping the pressure from dropping due to the increased water demand. These systems are a must have for anyone with inconsistent or low water pressure.

This compact water pressure system features:
  • Great for water storage/cistern systems, homes in private and municipal applications, general pressure boosting, sprinkler systems, farms, and commercial wash down systems
  • Stainless steel construction - made for years of operation - compliant with Federal Safe Drinking Water Act standards
  • Small 18" height x 13-3/8" wide compact design of the pump fits into small areas, under a sink, or in a basement
  • Can be mounted in any orientation for greater flexibility of installation
  • Versatile design with a 180° rotatable top cover and LCD display for multi-directional, front or rear plumbing applications
  • 1" inlet / outlet stainless steel inserts with molded-in hex grip
  • Integrated expansion tank and check valve included
  • Wide range of pressure adjustment settings; 14-80 PSI
  • Increases incoming pressure by 40 to 50 PSI
  • Maximum outlet pressure: 80 PSI
  • Maximum suction lift: 25 feet
  • Maximum operating temperature: 104° F.
  • Operates on a wide range of flows from flooded suction to 18 GPM
  • NEMA3R rated for indoor or outdoor applications
  • 0.8 hp power, single phase, 120V, 9.6 amps maximum input operating current
  • Built-in sensor helps protect these systems from many common failures including: low water shut off, surge protection, voltage underload, locked pump, open circuit, short circuit, or an overheated controller
  • Equipped with Bluetooth and WiFi to deliver customizable updates and notifications

Frequently Asked Questions

Q. "How much can I expect my water pressure to fluctuate after I install the constant water pressure system?"
A. The Constant Pressure System's constant output pressure should not fluctuate more than 1-2 PSI, even though the overall system's water flow requirement may change dramatically.

Q. "What is the incoming pressure requirement for these units?"
A. The Versaboost Pro constant pressure system requires a minimum of 20 psi if used with a utility or well pump. If you have a water storage tank or cistern, then you will need 1-19 psi if the water storage tank is installed above the booster. If your water storage tank is installed below the booster, then you need less than 1 psi.

Q. "What is the water flow requirement for the constant pressure unit?"
A. The system operates on a wide range of flows from flooded suction to 19 GPM at 14 PSI maximum. The Versaboost Pro can lift water from a source below the pumping unit upto 25 feet. There is not an incoming flow requirement, other than the system needs to be supplied with a constant supply of water to keep the unit completely full of water at all times with a maximum flow of 18 gpm. It is recommended that the system be supplied with inlet line that is 3/4" in diameter or larger. Please note although the unit has no water flow requirement other than being kept full at all times, you still must meet the minimum water pressure requirement of 1 PSI.

Q. "What is the difference between water flow and water pressure?"
A. Water flow refers to the amount of water coming out of a hose, faucet or other pipe fixture in a certain amount of time. Water pressure refers to the amount of force that is put on the water to make it move from one place to another, or to the amount of force the water exerts when coming out of the pipe. Water flow is the result of pressure on volume. Volume is the amount of water available for delivery, and pressure is the force exerted on it. For example if you have a pressure of 3 PSI forcing water through a 1/2" i.d. pipe it will have a lower flow rate than that same 3 PSI forcing water through a larger pipe.

Q. "What does flooded suction mean?"
A. A "flooded suction" refers to a situation in where water flows to the pump inlet from an elevated source by means of gravity.

Q. "My water is sandy and somewhat abrasive. Can I still use these systems?"
A. Pumping abrasive or sandy water can damage any pump's internal components. We suggest installing a sand separator before the constant pressure or boosting system if you have these water conditions. We have many sand separators for you to choose from. Please note: If you are considering adding a sand separator before the constant water system you must make sure that your water system meets the minimum flow rate for the sand separator to function correctly.

Q. "Will I experience water hammer while using the constant pressure system?"
A. The pressure tank helps reduce water hammer by acting as a system buffer. However you may still need a water hammer arrester as water hammer is caused by a rapid shut off of a valve on a long run at the end of your plumbing system and the constant pressure system is installed at the beginning of your plumbing system.

Q. "What other items and/or tools will be needed to install the constant pressure system?"
A. The manufacturer recommends but does not include: wrenches, screwdriver, pipe sealant, pipe fittings, nipples, check valves, ball valves, unions and a 100 PSI pressure relief valve.

Q. "Can the pump run dry without any damage?"
A. No, never run the pump dry.

Q. "Will this system be able to handle other liquids besides water?"
A. Per the manufacturer, this pump has been evaluated for use with water only.

Q. "What is NEMA3R rating mean?"
A. The NEMA3R rating means that the units enclosure provides a degree of protection from outdoor environmental factors like rain, sleet, and snow. It will not protect against dust or dirt. For indoor use this inclosure protects against accidental contact with live components, falling dirt, and light water splashing. The unit can be installed outdoors but the manufacturer recommends that the unit be shielded from direct sunlight to prevent overheating.
