UF-3 System vs Booster Pump Kit
Primary Function
You need to decide what you actually want to achieve with this equipment. The Watts Premier UF-3 is a complete ultrafiltration system. It uses three stages to remove sediment, volatile organic compounds, and microorganisms from your water. It provides clean drinking water directly. The Watts Premier Booster Pump Kit is not a filter. It is an add-on device designed to increase water pressure for reverse osmosis systems. It helps your existing RO unit work faster and more efficiently. If you already have a filter, you need the pump. If you need a filter, you need the UF-3.
Filtration Stages
The Watts Premier UF-3 system offers three distinct filtration stages. It starts with a 5-micron sediment filter to catch large particles. Next is an LVOC carbon filter to reduce volatile organic compounds. The final stage is a 0.1-micron hollow-fiber semi-permeable membrane for fine filtration. This multi-stage approach ensures comprehensive water treatment. The Watts Premier Booster Pump Kit has no filtration stages. It contains no filters or membranes. Its sole purpose is mechanical pressure enhancement. It does not clean water at all. It simply moves water through your system with more force. If filtration is your goal, the UF-3 is the only choice here.
Certification
Certification matters for verifying filter performance. The Watts Premier UF-3 includes WQA certified filters. This means the components meet specific industry standards for material safety and filtration effectiveness. You can trust the certified claims for sediment, VOCs, and membrane performance. The Watts Premier Booster Pump Kit has no filtration certification. It is a mechanical device, not a filter. It does not need WQA certification because it does not remove contaminants. It only affects water pressure. For certified water treatment, the UF-3 system provides the necessary verification.
Power Requirements
Power needs differ significantly between these two products. The Watts Premier UF-3 ultrafiltration system does not require electricity. It is designed to run at low water pressures without external power. This makes it easy to install under any sink without needing an outlet. The Watts Premier Booster Pump Kit requires electrical power. It includes a 110V transformer and needs to be plugged in. It operates the pump to boost pressure. You must have an electrical outlet nearby for installation. If you lack a nearby outlet, the UF-3 is the simpler option.
Physical Dimensions
Size affects where you can place the unit under your sink. The Watts Premier UF-3 measures 15 inches in height, 9 inches in length, and 8 inches in width. It weighs 6.6 pounds. The filter is 11 inches long with a push-button release for easy changes. The Watts Premier Booster Pump Kit measures 10 inches in length, 6 inches in width, and 6 inches in height. It weighs 7.05 pounds. The pump is black and compact. The UF-3 is taller but narrower in some dimensions. Both fit under standard sinks, but the UF-3 requires more vertical clearance.
Compatibility
You must ensure the product works with your current setup. The Watts Premier UF-3 is a standalone system. It does not need to connect to another unit. It works independently for ultrafiltration. The Watts Premier Booster Pump Kit is designed for compatibility with existing systems. It works with all standard and manifold filter units. It is specifically designed to integrate with any Watts Premier reverse osmosis filtration system. It includes fittings and tubing for easy integration. If you have an RO system, the pump complements it. The UF-3 stands alone.
Which Watts Premier System Fits You
You want clean tap water without electricity
The UF-3 system provides three-stage ultrafiltration using a 0.1-micron membrane, a carbon filter, and a sediment pre-filter. It operates at low pressures and requires no external power or holding tank. You get WQA-certified filters with easy push-button replacements. This unit delivers filtered water directly from your tap for drinking and cooking.
You have low pressure and need more flow
If your water pressure drops below 40 psi, this booster pump kit increases flow and tank fill times. It includes a 110V transformer, fittings, tubing, and a pressure shutoff switch. The pump operates quietly and works with standard manifold filter units. It enhances your existing RO system rather than filtering water on its own.
You need a complete under-counter filtration solution
This system is designed for under-counter installation with compact dimensions of 11 inches in height. It removes sediment and volatile organic compounds through its three-stage process. The brushed nickel finish fits standard kitchen aesthetics. You do not need to install a separate pump or electrical outlet, making it a self-contained purification unit.

Frequently asked questions
What are the physical dimensions of the Watts Premier UF-3 system?
The Watts Premier UF-3 measures 8 inches in width, 15 inches in height, and 9 inches in length. It weighs 6.6 pounds. Its compact footprint allows it to fit under most standard kitchen sinks. The brushed nickel finish helps it blend with modern fixtures. You can verify these measurements against your cabinet space before installation.
How big is the Watts Premier booster pump kit?
The booster pump kit measures 6 inches in width, 6 inches in height, and 10 inches in length. It weighs 7.05 pounds. The black color helps it remain discreet under the sink. These dimensions are slightly wider than the UF-3 but shorter in height. Ensure you have adequate vertical clearance for the pump.
Does the Watts Premier UF-3 require electricity to operate?
No, the Watts Premier UF-3 does not require electricity. It is designed for low-pressure under-counter ultrafiltration without external power. This makes it suitable for areas with limited electrical access under the sink. You only need a standard water line connection. The system relies on incoming water pressure to function effectively.
What model number identifies the Watts Premier booster pump?
The Watts Premier booster pump kit is identified by model number WP560043. This specific model is designed to increase water pressure for reverse osmosis systems. It helps solve flow rate issues caused by low incoming pressure. You should verify this model number matches your existing RO system requirements before purchasing.
What is the main functional difference between these two products?
The UF-3 is a complete filtration system that cleans water using three stages. The booster pump is an add-on component that increases water pressure. You cannot use the pump alone to filter water. You must pair it with an existing reverse osmosis system. Choose the UF-3 for standalone filtration and the pump for pressure enhancement.
Can I install the booster pump if I already have the UF-3?
No, you do not need the booster pump with the UF-3 system. The UF-3 operates on low pressure and does not require additional boosting. The pump is specifically intended for reverse osmosis systems that suffer from slow flow rates due to low inlet pressure. Adding it to the UF-3 would be unnecessary and redundant.
