Case Study — City Water Treatment
From Shutdowns to Sleepless Nights — to 365 Days of Flow.
Inside a California water plant, one Graco SoloTech™ hose pump and Liberty CES turned an impossible chemical into a year-long success story.
Quantified Benefits
Reversible clearing + single-roller action.
Single compression / revolution. Less heat. Less fatigue.
10 incidents avoided × 3–5 hrs × 2 techs.
Conservative $1k/hr × 30–50 hrs.
The Frequency of Failure → The Flow of the Fix
A municipal plant’s calcium hydroxide kept hard‑setting on every pause. James Riggins stepped into the gap — and engineered it out of existence.

Before SoloTech: when flow stopped, concrete happened.
A municipal facility used calcium hydroxide (Ca(OH)₂) for pH control. Its nasty habit: when it stops moving, it hardens like concrete.
- Outages/pauses → slurry crystallizes inside hoses and valves.
- Within hours: a chalky mass locks the pump solid.
- Restarts = line openings, hose cuts, flushes, and overtime.
- Multiple pump brands/types failed within months.
In plain language: the chemical kept killing pumps. Every outage froze the line; every freeze meant hours of digging, cleaning, and new parts.
In the gap: James reframed the problem.
Everyone treated it like “make the pump tougher.” James saw a chemistry + mechanics mismatch. Ca(OH)₂ doesn’t just clog; static = solid. Eliminate stagnation and friction — don’t just swap brands.
Dead zones, valves, and multi‑roller friction created hot spots/air pockets that hardened to stone.
Keep it moving. One path, one squeeze, reversible flow. Clear without opening the system.


SoloTech™ 30: single‑roller, 360° compression — motion by design.
- One roller • one hose • one squeeze per revolution — less heat, no localized fatigue.
- Thick‑wall engineered hose (EPDM/NBR) for abrasive, alkaline Ca(OH)₂.
- Reversible — clear lines instantly when flow stops.
- Self‑priming & high suction lift (≈29–33 ft) for reliable restarts.
- No valves, seals, or glands to crystallize shut or leak.
- Variable‑speed control — gentle dose or quick flush on command.
“We just swap the hose maybe once a year now. No clogs. It just moves calcium like toothpaste.” — James R.
