Water treatment chemical feed system quarterly maintenance checklist
A quarterly chemical feed system round is short on purpose: it catches the wear items that fail between annual services. This checklist is sized for a tech with a phone. Every item says what to look at and the photo that proves the round happened. Work is commonly verified against manufacturer's published instructions. Confirm the edition your authority having jurisdiction has adopted.

Who runs it
The water treatment service tech or maintenance mechanic on the quarterly mechanical-room round.
When in the schedule
Every quarter with the cooling tower and closed-loop checks, since a dry drum or dead pump lets the loop drift untreated between visits.
The checklist
Every item, and the photo that proves it
The photo count on each row is what RTI would require before the item can be submitted. Copy the list as is, or load it into RTI and let the gate enforce it.
Chemical supply
- 2 photos
Drum and day-tank level read
Level checked against the reorder mark, product matches the label for this loop, no settled or separated chemical in the tank.
- 1 photo
Tubing and containment checked
Suction and discharge tubing free of air locks and kinks, secondary containment or drip tray dry, no crystallization at fittings.
Metering pump and injection
- 2 photos
Metering pump seen to draw and inject
Pump stroking, drum level actually dropping over a timed count, discharge pressure building rather than the head just clicking dry.
- 1 photo
Injection point and check valve confirmed
Injection quill and check valve passing product into the flow, no back-siphon, no scale or crystal buildup blocking the quill.
Controller and area
- 1 photo
Controller reading and mode verified
Conductivity or ORP probe reading in a sensible range, controller in auto and dosing on demand, not left in hand or alarmed.
- 1 photo
Eyewash and PPE present in the area
Eyewash within reach and unobstructed, gloves and face protection stocked at the station — observed, not tested.
What usually sends this back
The failures are almost always the evidence, not the work
- Drum run empty because no one read the day-tank level, so the loop has been feeding nothing but makeup water for weeks.
- Metering pump clicking but not moving product past a fouled injection check valve, so the reading on the drum drops while nothing reaches the water.
- Controller in hand or off after a prior service and never returned to auto, so it stopped dosing on conductivity.
Run it with the Photo Gate
A checklist nobody can submit half-finished
Load this list into RTI, stick a QR tag on the area it covers, and the submit button stays locked until every mandatory item is answered and the 8 required photos exist. Approved walks roll into a branded turnover package with a tamper-evident record behind every line.
Submission state
The gate is enforced on the server, so it holds even if the phone is offline when the walk happens.
Common questions
- What does this water treatment chemical feed system quarterly checklist cover?
- 6 items across 3 sections, covering chemical supply, metering pump and injection, controller and area. Each item spells out what the person walking the job is actually looking for, not just a box to tick.
- Who should run this inspection?
- The water treatment service tech or maintenance mechanic on the quarterly mechanical-room round.
- When in the schedule should this walk happen?
- Every quarter with the cooling tower and closed-loop checks, since a dry drum or dead pump lets the loop drift untreated between visits.
- Why does every item ask for a photo?
- 8 of the 6 items call for photo evidence. A checklist answer without the photo is a claim; the photo is what makes the record worth something in a dispute and lets a reviewer approve work without re-walking the job.
- What most often fails a water treatment chemical feed system quarterly inspection?
- Drum run empty because no one read the day-tank level, so the loop has been feeding nothing but makeup water for weeks. Metering pump clicking but not moving product past a fouled injection check valve, so the reading on the drum drops while nothing reaches the water. Controller in hand or off after a prior service and never returned to auto, so it stopped dosing on conductivity.
- Can I use this checklist in RTI?
- Yes. Start a free RTI workspace, build this list as a checklist, and the Photo Gate holds the submit button until every mandatory item is answered and its photos are attached. Approved inspections roll into a branded turnover package with a tamper-evident audit trail.
