Correction and change log

Material changes to published figures, procedures or source links are logged here with the date and the reason. The log is empty because this is the first published version of the site. It will not stay empty: manufacturers reorganise their documentation regularly, and when a link moves we find its replacement within the same official domain, confirm it still covers the same models, and record the substitution here.

Recorded as unknown, and left unpublished

These are questions we researched and could not answer from a primary source. They are listed because an invisible gap invites someone to fill it with a guess.

  • Whether any single iron compensation factor is correct across manufacturers. Pentair uses 4 gpg per ppm for chart sizing; Whirlpool instructs adding 5 per ppm when programming a WHES30/WHES33 controller. These are different tasks with different documents and we have found no source that reconciles them into one universal rule. The site therefore shows both, labelled, and never averages or picks one silently.
  • How long water softener resin lasts, as a service life in years. Commercial articles widely repeat "resin lasts 10 to 15 years". We could not trace that range to any manufacturer document or standards body. The closest traceable statement is Whirlpool’s, and it says something different: that the average lifespan of the UNIT is around 10 years (see whirlpool-unit-average-lifespan). Those are not the same claim. The resin page therefore treats age as context and never as a diagnosis, and publishes no service-life figure of its own.
  • Universal drain line dimensions — air gap, maximum height, maximum run or hose diameter — valid across manufacturers. Whirlpool publishes 3/8 inch inside diameter, 8 feet maximum height, 30 feet maximum horizontal run and a 1½ inch air gap for its own equipment. Those figures are recorded and attributed. We found no source establishing them as valid for other manufacturers, and Whirlpool itself defers to local plumbing code on whether a flexible hose is permitted at all. The drain page therefore states dimensions only with the manufacturer attached, and its decision flow can end in "not enough information to give a safe measurement".
  • What a pressure recovery in bypass proves on its own. WaterBoss reads pressure returning in bypass as a good indication that the resin needs replacing. Whirlpool documents the same comparison but sends the owner to clean the media first. Both are manufacturer statements about their own equipment, and no source reconciles them. The resin decision tool therefore treats this observation as supporting evidence that needs confirmation, never as a verdict.
  • The correct regeneration frequency for an unspecified softener model. Pentair sizes on a three-day minimum interval; demand-initiated controllers decide for themselves from metered use. We present 3, 5 and 7 day scenarios as planning columns and do not tell anyone what interval their unit should use.
  • No default value set for the Fleck 5600SXT master parameters, tied to a stated tank size, resin volume and configuration, was found in either Pentair service manual. Both manuals publish acceptable ranges and refer the reader to a professional dealer before master programming. Independent guides publish complete "recommended" value sets for nominal 32k and 48k systems; none traced to Pentair. This site publishes ranges and the missing-data list instead.
  • No Culligan document was found that publishes a settings list, a control layout or an error vocabulary applying across all Culligan residential softener families. Eight owner’s guides were read on 4 September 2026 and they differ in keypad, menu, documented defaults and error vocabulary. Culligan’s own troubleshooting article stays at symptom level and routes to a dealer.
  • No Pentair source was found listing which finished softeners sold by other brands are built on the Fleck 5600SXT control valve. The valve is sold to system builders, so the brand on the tank is not evidence of the control. This site tells the reader to read the label on the control itself rather than listing brands.
  • The Pentair Fleck 5600SXT manuals are internally inconsistent about the unit of the Unit Capacity (C) parameter for a softener. The Master Programming chart labels it "Unit Capacity (Grains)", and the body text instructs the reader to enter the capacity of the media bed in grains of hardness when configuring a softener system — but the range printed immediately below reads "1-999,900 gallons (100-9,999,000 Liters)". Both the upflow and the downflow manual carry the identical contradiction. Upflow printed page 8, downflow printed page 9; verified in both documents on 4 September 2026. We do not guess which unit governs. The site publishes the grains instruction, states that the printed range is expressed in gallons and litres, and says the discrepancy is unresolved. Anyone about to enter a value should confirm it against the display on their own control.

Whirlpool Water Softener Owner’s Manual — Models WHES30 and WHES33 PDF

  • For Whirlpool WHES30 and WHES33, the owner’s manual instructs adding 5 to the hardness number for each 1 ppm of ferrous (clear water) iron. Its worked example is 20 gpg hardness plus 2 ppm iron times 5, giving a hardness number of 30.

  • Whirlpool states that a water softener will reduce moderate amounts of ferrous (clear water) iron but will not remove ferric (red water), bacterial, organically bound or colloidal iron. Clear water iron is clear when drawn and clouds yellow or brown within roughly 15 to 30 minutes as it oxidises.

  • Whirlpool describes a salt bridge as a hard crust that leaves an empty space between the water and the salt so no brine is made. To check, measure from the floor to the rim of the softener, mark a broom handle, and push it straight down into the salt; a hard object felt before the mark reaches the top is most likely a bridge. It warns not to use sharp or pointed objects, which may puncture the brine tank, and not to break the bridge by pounding on the outside of the salt tank.

Old or Expired Resin Web page

  • Whirlpool attributes resin expiry to age, oxidation as it physically breaks down, and expansion in the tank. It states that expired resin causes a pressure drop in the tank leading to low water pressure in the home, and that resin can escape the tank into household plumbing, where it may be noticed as a pinch of beads in the back of a toilet.

How Much Resin Should be in the Tank? Web page

  • Whirlpool states a softener resin tank should typically be around two-thirds to three-quarters full of resin, and that the empty space above it, the freeboard, exists so the resin can move during backwash and rinse out dirt and rust particles.

Will a higher hardness setting give me softer water? Web page

  • Whirlpool states that setting the hardness number higher than the true supply hardness does not produce softer water: the unit still delivers the same degree of softness, 0 to 3 gpg, but uses more salt and more water because it recharges more often, which reduces the softener’s efficiency.
