  • Everything else is unchanged from the smaller units, including the absence of any NSF/ANSI 44 listing and the same four-button control head that owners find impenetrable.
  • judged on evidence it rests on exactly the same nothing as the rest.

  SoftPro ECO City

  • Its weakest is disclosure, because SoftPro publishes no rated service flow rate for the ECO anywhere on the product page, only that it suits 3/4 inch plumbing.
  • Nothing in the SoftPro catalogue holds a system-level NSF or WQA performance certification, so the hardness reduction claim rests on the manufacturer's word and on third-party testing published against the Elite rather than this model.

  • Regeneration draws 50 to 75 gallons per cycle, a figure worth checking against a septic system before buying.
  • The brine tank capacity does not scale with the resin bed, so a household big enough to need this unit will refill salt more often than the specification implies.

  • Product-line. r/WaterTreatment and r/WaterSofteners carry a dozen live Aquasure threads and nearly all of them concern the Harmony softeners.
  • Owners report straightforward DIY installation, hardness falling to zero grains and low salt consumption.
  • The adversarial side is specific and it lands on this size: one thread describes a resin cartridge rupture on a 64,000 grain fine mesh unit bought through Amazon, and a second describes a Harmony resin tank basket failing and discharging beads into house plumbing.
  • The standing objection is that the hardware is made in China against a Fleck or Pentair valve; the standing defence is that spare parts are cheap and Aquasure publishes repair videos for most faults.

  • The complaints are consistently about the company rather than the equipment: shipping delays, warranty terms described as confusing, and post-sale service.
  • One incident, a defective unit shedding media into household fixtures after professional installation, appears as two separate threads in two subreddits and is one event rather than two reports.
