Where each walk sits in the schedule
- Water treatment chemical feed system quarterly maintenance checklistquarterly
- Every quarter with the cooling tower and closed-loop checks, since a dry drum or dead pump lets the loop drift untreated between visits. Run by: The water treatment service tech or maintenance mechanic on the quarterly mechanical-room round.
- Water treatment chemical feed system annual maintenance checklistannual
- Once a year, timed with the closed-loop and condenser-water annual so probe drift and pump output get corrected against a real sample. Run by: The water treatment service contractor on the annual service, when the loop can be sampled and the controller taken through its ranges.
What most often fails on a water treatment chemical feed system
- 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.
- Metering pump output taken from the dial setting and never checked against a draw-down, so the loop is over- or under-dosed all year.
- Conductivity probe cleaned but never checked against a reference solution, so the controller doses to a drifted number.
- Injection quill left in place until it snaps off in the flow because scale was never cleared from it on a service.
Common questions
- Which water treatment chemical feed system maintenance rounds do these checklists cover?
- Water treatment chemical feed system quarterly maintenance checklist (quarterly): Every quarter with the cooling tower and closed-loop checks, since a dry drum or dead pump lets the loop drift untreated between visits. Water treatment chemical feed system annual maintenance checklist (annual): Once a year, timed with the closed-loop and condenser-water annual so probe drift and pump output get corrected against a real sample.
- Who runs the water treatment chemical feed system maintenance round?
- The water treatment service tech or maintenance mechanic on the quarterly mechanical-room round. The water treatment service contractor on the annual service, when the loop can be sampled and the controller taken through its ranges.
