Excalibur Sureflo® Premium Reverse Osmosis System – Supplied & Professionally Installed by 4Most Energy

The Excalibur Sureflo® Premium Reverse Osmosis System is a high-pressure drinking-water purification system designed to provide treated water directly at a dedicated drinking-water faucet. The manufacturer describes the current system as a 7-stage, 100 GPD reverse osmosis system using membrane technology, with applications including municipal, well and lake water.

The treatment process can include sediment filtration, carbon filtration, ceramic filtration, a booster pump, a thin-film composite RO membrane, remineralization and coconut-shell carbon post-filtration, depending on the selected configuration. The supplied manual explains that the sediment stage reduces suspended material such as silt, dirt, scale and rust, while carbon filtration helps reduce chlorine and substances associated with taste and odour. The RO membrane separates dissolved minerals from the incoming feed water, with rejected material directed to drain.

The system incorporates a booster pump to increase pressure for the RO membrane process. The manufacturer documentation specifies a 24-volt booster-pump system, while the manual identifies a required 110 V / 60 Hz power supply for its booster-pump configurations.

Professional installation requires suitable access to a potable cold-water supply, household drain connection and electrical power. The installation location must remain protected from freezing temperatures and direct sunlight. The manufacturer recommends softened water where applicable because it can extend RO membrane life.

System sizing and configuration should be based on the home's water conditions and intended drinking-water demand. Feed-water requirements in the installation guide include 30–100 psi, 40–100°F, maximum 1,800 mg/L TDS, turbidity below 1.0 NTU, hardness below 170 mg/L as CaCO₃, iron below 0.1 mg/L and manganese below 0.05 mg/L.

4Most Energy can coordinate the equipment selection, plumbing connections, system commissioning and operational checks so the RO system is installed according to manufacturer requirements and applicable plumbing codes.

1. Request Installation Quote Contact 4Most Energy to arrange an assessment and installation quote.

2. System Sizing Consultation Review water source, water chemistry, pressure, available installation space and intended drinking-water demand.

3. Equipment Recommendation Select the appropriate Premium RO configuration based on the application and available water-quality information.

4. Installation Scheduling Arrange a suitable installation appointment.

5. Removal of Existing Equipment Where applicable, disconnect and remove the existing RO equipment and prepare the installation area.

6. Installation & System Connection Installation may include:

  • RO manifold assembly
  • sediment and carbon filtration
  • RO membrane
  • booster pump
  • storage tank
  • dedicated drinking-water faucet
  • cold-water feed connection
  • RO drain connection
  • electrical connection for the booster pump
  • applicable optional filtration stages

The manufacturer requires the RO system to be connected to a potable cold-water supply. The drain connection should not be connected to a dishwasher drain or located near the garbage disposal.

7. Safety & Leak Testing Check plumbing connections, tubing, feed-water supply, drain connection, electrical operation and system pressure.

8. Final Commissioning The system is sanitized, started and checked for correct operation. The manufacturer instructs installers to discard initial tank production during startup because the membrane is shipped with preservative and the system requires flushing.

Manufacturer Warranty

The current Excalibur product page specifies an unlimited 7-year warranty, excluding consumables. The supplied brochure also advertises a 7-year unlimited warranty, excluding consumables.

Consumable filters are subject to scheduled replacement. The installation manual recommends replacing the RO filters, excluding the membrane, approximately every six months, although local conditions may require more frequent replacement. The manual lists a typical RO membrane life expectancy of three to five years when a water softener is installed before the RO system.
