Boiler blowdown controls and alarms do, however, require testing and inspection.
General guidance is given in Health and Safety Executive Guidance Notes BG01 and INDG436.
8.3 General weekly maintenance:
- Take a sample of the boiler water through a sample cooler, measure its conductivity
(calculate the TDS).
- Check the conductivity controller calibration with the boiler at normal operating pressure.
- Check that the blowdown valve shuts when the power is removed.
- Operate any stop valves to ensure that they shut off, and move freely.
8.4 General six months maintenance:
- Isolate the system (or with the boiler empty), remove the conductivity probe.
- Clean the tip with fine abrasive paper/pad and wipe the insulation with a cloth.
- Examine the control / solenoid / stop valves and other fittings.
- Clean and refit or replace any parts necessary.
