In care homes and healthcare environments, water safety 💦 is a delicate balancing act.
To prevent Legionella bacteria from growing, hot water must be stored at 60°C or above and distributed at a minimum of 50°C (55°C in healthcare settings).
However, water at these temperatures can cause severe scalding in seconds to vulnerable residents. 🥵
That’s where Thermostatic Mixing Valves (TMVs) come in.
TMVs blend hot water with cold water right at the point of use (such as taps, showers, and baths) to deliver a safe, controlled outlet 🌡️ temperature—typically between 38°C and 43°C—without cooling down the main supply system.
Keeping Your TMVs Compliant & Safe:
✅ Regular Maintenance: TMVs contain moving parts and strainers that can scale up or fail over time, requiring regular servicing.
✅ Fail-Safe Testing: Valves must undergo an annual fail-safe test to guarantee that the hot water supply shuts off instantly if cold water supply fails.
✅ Audit-Ready Logging: All servicing, temperature checks, and fail-safe results must be documented in your water safety logbook.
Our qualified engineers provide comprehensive TMV servicing, testing, and water hygiene management for care facilities across South Wales to ensure complete safety and legal compliance.
