  • For a family that empties the tank regularly, the upgrade is worth the money.

  Aquasure Premier Pro 100 GPD

  • The LED faucet is a convenience rather than a measurement: it counts time or volume rather than testing water quality, and it does not replace a TDS meter.

  • A larger membrane refills the three gallon tank faster after it is drawn down, which is the practical complaint people have about tank RO systems in households that drink a lot of water or fill pots from the tap.

  Express Water ROELITE9

  • Five separate stages is a real architectural difference rather than a badge, and at nearly twice the weight of the standard chassis the build is visibly heavier.
  • Express Water publishes no pH range, no mineral output figures and holds no certification for this model, which for a product sold on mineral content is the central weakness.
• Certification CoverageAquasure Premier Pro 100 GPD: 2Express Water ROELITE9: 2

  Aquasure Premier Pro 100 GPD

  • Certification is identical to the rest of the Premier range, which is to say Aquasure's only NSF listing covers two membrane part numbers for material and structural integrity and nothing on this system is certified for contaminant reduction.

  • The drain ratio stays at 1.5 to 1, so the extra output does not come at the cost of wasted water, which is the trade some manufacturers make at this capacity.

  • Product-line.
  • Two r/WaterTreatment and r/HomeMaintenance threads cover the Premier RO platform.
  • One owner reports 420 ppm TDS at the faucet on a new install, settling to about 360, which is a poor rejection figure and the more relevant of the two for a system sold on membrane capacity; the second describes the Flowlok leak-detection disc deploying during a filter change when a drain-line fitting leaked.
  • Nothing addresses the 100 GPD membrane or the LED faucet specifically.

  • Product-line. r/HydroHomies concludes Express Water's alkaline filtration does produce alkaline water but that strength drifts over cartridge life, which bears directly on a model sold on five mineral stages.
  • Wider r/WaterTreatment threads recommend the platform for taste and value while calling the install involved.
  • No thread names the Elite specifically.

  • WaterFilterGuru bench-tested the platform's RO5DX with Tap Score lab analysis at 8.13 overall and measured a remineralisation stage lifting pH to 9.0.
  • TapWaterData's certification audit records no certifier listing for the Elite, so its mineral claims rest entirely on Express Water's own data.

  • Product-line.
  • IrixGuy's Adventure Channel, 98,800 subscribers, has two independent owner reviews of the Premier RO - one after several months at 6,100 views and a several-years follow-up - and a separate third-party self-install walkthrough covers the same 4-stage system.
  • None names a specific capacity, so this is the Premier line rather than this model.
  • The pump configuration is not addressed separately, and the RO roundups that bench-test at this price point do not include Aquasure.
  • Brand-level coverage is the Harmony softeners: DIY Homestead Projects at roughly 115,000 views, NKP Home Improvement at roughly 94,000, geminidrums at 15,000 on the fine mesh and IrixGuy's two-year owner review at 13,000.

  • The Premier Pro 100 GPD reads 4.2 of 5 from 16 ratings on ASIN B07FKCM6T2 - a real pool just above the ten-review floor, and the lowest product-level Amazon figure on any Aquasure system.
  • It sits two tenths below the softener line the rest of this brand's Amazon evidence rests on, which is worth saying wherever that figure is used.

  • Home Depot reads 4.2 of 5 from 10 reviews on this exact system.
  • That is exactly the ten-review floor, so the figure is scorable but should be read as the thinnest usable pool in this brand's set, and the 75 GPD Premier Advanced at 4.5 from 41 is the better-evidenced point of comparison on the same platform.
  • Both pools are native, with verified-purchase entries and Aquasure replying under its own support address.
  • Across the three Premier configurations Home Depot holds, the ordering runs 4.5, 4.2 and 4.0, which puts this in the middle on a count too small to make that ordering mean much.
