You hear water in the garage at 2 a.m. The house is not using taps. The drain line at the softener is still moving. That is the fault EPA names, not a long shower. Clear Water Pros SD connects you with a licensed water-treatment pro. The brand does not service control valves itself.
Persistent drain flow is a malfunction
EPA’s May 2026 water-softener guide says demand-initiated regeneration responds to use and hardness rather than a fixed timer. Persistent drain flow can indicate a malfunction. Follow model-specific installation, bypass, and maintenance instructions.
Regeneration should finish according to the model’s programmed cycle. A drain that never quiets is the persistent-flow clue EPA flags. On a City of San Diego tap, hardness typically averages about 16 grains per gallon on the City plumbing page. Helix’s imported-supply figure is about 14 grains. Do not copy the City figure onto La Mesa or a private well.
Sort running drain from a wet floor
Water on the slab is a leak. Isolate with the bypass or the supply shutoff if you can do that dry. Do not force a stuck handle. See water softener leaking.
Some standing water can be normal. An unusually high level, or a level that does not drop after regeneration, is the fault Culligan flags. See brine tank full of water.
A drain that keeps running while the brine tank looks normal needs model-specific diagnosis. Check the salt and inspect for a bridge or mush without opening the valve. Confirm whether the system is regenerating at its programmed time.
Do not open the control head. Stay off wet electrical gear.
What you can do before the pro arrives
Put the unit in bypass if the manual allows it and the handle is not stuck. If the drain keeps running, use the model’s isolation instructions or the supply shutoff only if you can do that dry, then call.
Note whether the sound is the drain, the brine fill, or a well pump on an inland lot. A continuously running well pump is a separate well-contractor question.
EPA says oversizing can waste water. A unit that regenerates every night on a timer, with a two-person household, is a programming and sizing question. Demand-initiated heads exist for that reason. No universal year cutoff says the valve is finished. How long a water softener lasts walks age versus condition.
Frequently asked questions
Is a late-night regeneration always a fault?
A cycle can run at night. Compare its duration with the exact model manual. Flow that persists beyond the specified cycle is the clue that needs diagnosis.
Should I unplug the control?
Follow the model manual. Power and water isolation are separate, so unplugging is not a substitute for the approved bypass or shutoff procedure.
Could irrigation be on the softener?
EPA says to exclude irrigation demand when appropriate during sizing. Ask the installer whether landscape lines were intentionally left off the softened side.
