Core Responsibilities

Primary Functions

Perform full-service installations of point-of-use and whole-house water filtration systems, including reverse osmosis (RO) units, carbon filtration systems, UV sterilizers, and water softeners, ensuring proper mounting, secure connections, and manufacturer-specified flow rates.
Diagnose and troubleshoot mechanical, electrical, and hydraulic faults on residential and commercial filtration systems using diagnostic tools, multimeters, pressure gauges, and TDS/pH meters to isolate issues and restore system performance.
Conduct routine preventive maintenance visits, flush and replace filter cartridges, change membranes, disinfect systems, adjust settings, and document maintenance actions to maximize system longevity and water quality.
Complete on-site water quality testing (TDS, turbidity, pH, chlorine, hardness) and interpret results to recommend corrective actions, upgrades, or additional treatment stages to meet customer expectations and local regulations.
Install, size, and configure booster pumps, pressure tanks, valves, and bypass assemblies for proper water pressure management and system efficiency in both single-family homes and commercial facilities.
Read, interpret, and execute installation schematics, technical manuals, and manufacturer wiring diagrams to ensure accurate assembly, correct wiring of solenoids/timers, and safe electrical connections per code.
Cut, thread, solder, and join copper, PVC, PEX, and CPVC piping; make pressure-tight connections and run new plumbing lines for filtrations systems where necessary.
Perform membrane change-outs and sanitization procedures for RO systems, following manufacturer and WQA-recommended practices to prevent system fouling and microbial contamination.
Calibrate and maintain service equipment, including hand tools, power tools, meters, and diagnostic devices; ensure vehicle stock of common parts and consumables for first-time-fix goals.
Create clear, professional service reports and digital work orders that document findings, actions taken, parts used, and next-step recommendations for clients and the operations team.
Provide detailed customer education and demonstrations on system operation, filter change intervals, warranty requirements, and basic troubleshooting steps to increase customer satisfaction and reduce unnecessary return visits.
Manage inventory of filters, membranes, UV lamps, and spare parts; order replacements, track warranty parts, and coordinate returns with manufacturers when required.
Escalate complex technical issues to manufacturer technical support or engineering teams and collaborate on warranty claims, troubleshooting upgrades, or system redesigns when field repairs are not feasible.
Follow safety protocols and regulatory requirements on-site, including personal protective equipment (PPE), lead-safe practices, confined space awareness, and safe handling/disposal of used filters and cartridges.
Perform pre-installation site surveys to assess plumbing access, water pressure, electrical availability, and space constraints; provide accurate job-time estimates and materials lists for efficient scheduling.
Coordinate with general contractors, plumbers, electricians, and facility managers on commercial projects to integrate filtration systems into existing building services and adhere to project timelines.
Troubleshoot and repair pump assemblies, solenoid valves, float switches, and control boards in integrated water systems; replace worn mechanical parts and validate system operation post-repair.
Participate in emergency call-outs for service interruptions, contamination events, and critical repairs for hospitals, restaurants, and municipal customers requiring rapid response.
Enforce quality control standards by testing final water output after service and adjusting system settings to achieve target specifications before leaving the job site.
Use mobile devices and company software to log time, update job statuses, capture photos of installations, and submit invoices and customer signatures electronically.
Maintain a professional appearance and strong customer service etiquette, handling on-site questions, explaining service invoices, and upselling recommended upgrades or maintenance plans when appropriate.
Train and mentor junior technicians and apprentices in safe installation practices, diagnostic routines, and customer service expectations to elevate team competency and first-time-fix rates.

Secondary Functions

Support internal product development by providing field feedback on recurring failure modes, common installation challenges, and ideas for improved serviceability to operations and engineering teams.
Participate in periodic safety and technical training sessions, including manufacturer certification classes and company-led competency evaluations.
Assist scheduling and dispatch with route planning input to optimize travel times and first-visit resolution, particularly in high-density service territories.
Help maintain the shop and service vehicle inventory, ensuring cleanliness, secure storage of hazardous materials, and accurate tooling availability for field assignments.
Contribute to the creation and update of technical standard operating procedures (SOPs), installation checklists, and troubleshooting guides used by the broader service organization.
Support sales and customer success teams by conducting technical site assessments for lead-generation projects and providing written estimates for system upgrades or conversions.
