What this sheet is for
Turn the plant operator's walk-round into a row of readings that can be laid beside yesterday's, so a filter that is slowly blinding or a day tank that is emptying faster than it did last week is seen as a trend.
Who it is for
Plant operators and duty managers on commercial, hotel, school, club and residents' pools with a plant room and automatic dosing.
How to use it
- Fill in the site, the week and the filters once at the top.
- On each round, write the filter inlet and outlet gauges, flow meter and balance tank level exactly as read.
- Note which filter was backwashed and clear the strainer baskets.
- Check the dosing day tanks, pumps, probes and bulk stock, and the ventilation and spill kit in the room.
- Record deliveries, faults and anything reported for repair.
What is on the sheet
2 pages, in this order:
Page 1
Printed under the title: The plant operator's walk-round on a commercial or shared pool: filters, circulation, dosing, chemical stock and the room itself, one row per round so a drift shows up over the week.
Readings as found, ranges from your procedures. Every gauge and level on this sheet is written down as read — the sheet does not say what the reading ought to be. Your working ranges come from your pool operating procedures and your filter and dosing equipment manufacturers; keep a copy of them in the plant room and compare against those.
Write-on lines: Site / pool · Week beginning · Plant operator · Filters (number & type)
Circulation and filtration
Table, 12 rows: Date · Time · Filter inlet · Filter outlet · Flow meter · Balance tank · Strainer baskets · Backwash done · Leaks, noise, vibration · Initials
Page 2
Dosing, chemical stock and the room — same rounds as the front
Table, 12 rows: Date · Sanitiser day tank · pH corrector tank · Dosing pumps running · Controller probes · Bulk stock (drums, bags) · Ventilation & spill kit · Deliveries or faults · Initials
Once this week
- Compare the controller's readings against a hand test at the same moment, and note the difference
- Check every drum and bag is labelled, bunded and stored apart as your supplier's data sheets set out
- Check the eyewash, shower or first aid point in the room is stocked and reachable
- Check the PPE for chemical handling is present, clean and fit to use
- Walk the pipework and valves for weeps, corrosion and labels that have faded
- Read the plant room's own procedures and note anything on this sheet that has drifted from them
Ruled lines: Notes — faults reported, parts ordered, deliveries expected
Questions
Why are there no working ranges printed beside the gauge columns?
Because a filter's clean and dirty pressures, its flow rate and the balance tank level are set by your filter and dosing manufacturers and your own pool operating procedures. Keep those in the plant room and compare the row against them; the sheet only records what was read.
Where do the water test results go?
On the Pool Chemical and Maintenance Log. This sheet is the plant, not the poolside test; the two are read together at the end of the day.

Put a real number on how busy the pool was and when, so the dilution, the dosing and the staffing can all be read against the same count instead of against a guess.
