Find commissioning details and previous reports. Unstable temperatures, scale, low flow or failed checks may need corrective work as well as revised timing. Booking another visit sooner will not fix an unsuitable installation.
Read HSE's guidance on hot and cold water systems for how scald prevention and legionella control fit together, including particular concerns in healthcare and care settings.
Separate the activities on the schedule
Ask for monitoring, relevant performance tests and servicing to be described separately. Include the cleaning, inspection or component work required by the manufacturer. A pass box needs a test method and criteria behind it.
The mixed temperature at the tap and the upstream hot supply answer different questions. A comfortable tap reading does not prove the hot-water system meets its hygiene controls. Keep the valve work connected to the wider water-management plan.
HSE's technical guidance, HSG274 Part 2 explains the broader hot and cold water system context behind those arrangements.
Make each visit useful
Supply valve details, previous findings and instructions, and arrange access. Agree who approves repairs and any temporary restriction on use. Occupants may need another washing facility during the work.
Request the valve location, tasks, observations, results, repairs and remaining actions. If a valve cannot be reached, it is still unfinished work and needs an assigned follow-up rather than disappearing from the report.
Frequently asked questions
Does an annual service cover every requirement?
Not necessarily. The full programme may need several monitoring, testing and service activities. Follow the valve instructions and requirements of the premises, informed by assessment and results.
What happens if a valve fails a test?
Agree what happens to the outlet and what repair or replacement is needed. Keep the failed result with the corrective action. A later pass should show what changed beforehand.
Should a new owner continue the previous schedule?
Check the inherited information first: valve types, users, recent results and changes to the system. Continue effective arrangements while filling gaps; an ownership change does not close unfinished repairs.
