A high school in New Jersey returned from spring break to find a burst pipe had been running for nine days — damaging 4,200 square feet of flooring, ceiling tiles, and electrical fixtures at a cost of $218,000. The pipe had shown corrosion at the last inspection eight months earlier. The observation was noted. No work order was created. The repair would have cost $1,400. In OxMaint, a flagged inspection finding automatically generates a work order. OxMaint automates school plumbing PM schedules — restroom fixture inspection, water heater servicing, backflow prevention testing, drain cleaning, and Legionella risk management — so plumbing problems are caught on inspection, not discovered by water damage.

Six Plumbing Systems OxMaint Maintains in School Buildings
School plumbing maintenance covers six systems with distinct inspection frequencies, failure modes, and compliance requirements. Each one runs quietly until it fails — and when it fails in a school building occupied by students, the consequences are immediate and expensive. OxMaint registers every system component as an asset with its own PM schedule. Start free and build your plumbing asset register today.
SIX PLUMBING SYSTEMS — OXMAINT PM SCHEDULE AND COMPLIANCE
Restroom Fixtures
WC cisterns, flushometers, urinals, basins, and soap dispensers — daily operational check, monthly condition inspection, and same-day repair work orders for any fault. Restroom avoidance by students is the most visible consequence of deferred plumbing maintenance
Hot Water Systems
Water heaters, calorifiers, and circulation pumps — monthly temperature log (60°C / 140°F minimum storage) for Legionella risk control. Annual service and anode inspection. OxMaint tracks storage temperature per unit and alerts when readings fall below the control threshold
Backflow Prevention
Reduced pressure zone (RPZ) and double check valve (DCV) assemblies — annual test by a certified tester, certificate filed with the water authority. OxMaint tracks each device's test due date and generates the contractor booking reminder 6 weeks before expiry
Drainage Systems
Floor drains, gully traps, and waste pipework — quarterly drain CCTV survey in high-risk lines, annual high-pressure jetting in kitchen and sports facility drains. OxMaint tracks blockage history per drain to identify chronic problems before they cause flooding
Supply Pipework
Cold water supply pipes, isolating valves, and expansion vessels — annual visual inspection for corrosion, joint integrity, and insulation condition. Seasonal shutdown isolation valves exercised to confirm operation. OxMaint flags corroded sections for repair before failure
Legionella Risk Programme
Monthly temperature checks, quarterly flushing of infrequently used outlets, bi-annual risk assessment review, and annual cold water tank inspection — all required under HSE ACOP L8 (UK) or ASHRAE 188 (US). OxMaint auto-generates every task on the correct schedule
The Complete Plumbing PM Schedule
School plumbing PM runs across five frequencies — daily restroom checks through annual system inspections and certifications. Each frequency catches a different class of problem. Missing any one creates a gap that predictably leads to either water damage or a compliance violation. OxMaint generates every task automatically from the plumbing asset register.
PLUMBING PM SCHEDULE — FREQUENCY BY TASK CATEGORY
Daily
5 min
Restroom Operational Check
All WCs and urinals flushing — no running or blocked fixtures

Monthly
1–2 hrs
Legionella Controls and Temperature Logging
Hot water storage temperature — 60°C / 140°F minimum at calorifier and water heaters
Cold water storage temperature — below 20°C / 68°F at all cold water tanks
Hot water delivery temperature — 50°C / 122°F within 1 minute at sentinel outlets
Flush all infrequently used outlets — any outlet unused for 7+ days must be flushed for 2 minutes
Quarterly
Half day
Drainage and Fixture Inspection
Kitchen and sports facility drains — high-pressure jet clean, flow rate confirmed
Restroom fixture condition audit — cisterns, flushvalves, and waste fittings inspected per block
Expansion vessel pressure check — all potable water expansion vessels
Accessible pipework visual — corrosion, joint weeping, and insulation condition
Annual
Full day
Certification and System Service
Backflow prevention device test — RPZ and DCV assemblies tested by certified tester, certificate filed
Water heater/calorifier service — anode inspection, thermostat calibration, pressure relief valve test
Cold water storage tank inspection — clean, condition, and lid integrity
Legionella risk assessment review — update scheme and control measures for any system changes
Drain CCTV survey — selected high-risk sewer lines; root ingress, collapse, or offset joints
"The water authority sent us a notice in March — our backflow preventer on the science lab supply had not been tested in 26 months. They gave us 14 days to test or face disconnection. We'd had no system to track it. Since OxMaint, the backflow test due date is tracked against each device, a 6-week reminder fires automatically, and the contractor books before the window closes. We have never missed a test date since."

Plumbing Compliance Readiness: Without vs With OxMaint
School plumbing compliance is not a single certificate — it is a continuous programme of documented checks. A water authority, health department, or insurer can request any test record at any time. OxMaint stores every record against the individual asset and makes the complete history retrievable in under 2 minutes.

Frequently Asked Questions
Legionella pneumophila proliferates in water systems held between 20°C and 45°C — particularly in stagnant water in infrequently used outlets. In UK schools, HSE Approved Code of Practice L8 requires a written Legionella risk assessment, a documented control scheme, and monthly temperature checks of hot and cold water at sentinel outlets. In the US, ASHRAE Guideline 12 and the CDC recommend a Water Management Programme for all school buildings. OxMaint generates monthly temperature check work orders per calorifier and per sentinel outlet, and triggers flushing work orders for any outlet unused for 7 or more days.
Annual testing is required in virtually all US jurisdictions and under Water Regulations in the UK. The test must be carried out by a certified backflow prevention tester and the certificate filed with the water authority within the specified period after test. Failure to test can result in water supply disconnection — in the case above, the school received a 14-day notice. OxMaint tracks each RPZ and DCV assembly as an individual asset with its own test due date, generates a 6-week advance reminder, and stores the certificate against the asset once testing is complete.
Hot water must be stored at a minimum of 60°C (140°F) at the calorifier or water heater to prevent Legionella proliferation. It must be delivered at a minimum of 50°C (122°F) within one minute at sentinel outlets (the first and last outlets on each circulation loop). Cold water must be maintained below 20°C (68°F). OxMaint logs these temperatures monthly per unit — a reading below 60°C in storage generates an immediate alert and an urgent work order to the maintenance team before the system is used the following day.
Three actions prevent the majority of break-period water damage: full building walkthrough before closure (identifying any dripping fixtures, running water sounds, or damp areas), isolation of non-essential water supplies to unused areas in extended breaks, and temperature monitoring if the building is not heated during winter breaks. OxMaint generates a pre-break closure checklist from the plumbing asset register, and the re-opening commissioning check list on return. Buildings that operate OxMaint's shutdown protocols have not reported a break-period burst pipe claim since deployment.
Yes — every backflow preventer, calorifier, and drain is an individual asset in OxMaint with its own inspection schedule, test record, and maintenance history. The district dashboard shows plumbing compliance status across all buildings: which backflow devices are due for test, which calorifiers have not been temperature-checked this month, and which drains are overdue for jet cleaning. One export covers the complete plumbing compliance record for any building, any system, any date range. Start your free trial to register your plumbing assets today.
