Thermostatic mixing valves play a quiet but critical role in building safety. When they are working properly, no one notices them. When they are not, the risks escalate quickly. For facilities managers, understanding how to service a TMV properly is not just a technical exercise, it is part of protecting users, maintaining compliance, and avoiding preventable incidents. This guide explains how TMV servicing should be approached in real buildings, not just in theory. It covers

When it comes to water safety and compliance, not all valves serve the same purpose. Two of the most commonly specified devices in plumbing and mechanical services are TMVs (Thermostatic Mixing Valves)  and RPZ valves (Reduced Pressure Zone valves) . While both are critical for protecting end users, they work in very different ways and address very different risks. At Titan Water , we’re often asked: what’s the difference between a TMV and an RPZ valve?  In this article, we’l

If you manage a building with hot water systems, you’ve almost certainly come across the term TMV . It stands for Thermostatic Mixing Valve , a small but crucial device that protects users from scalding and supports water safety compliance. Whether you look after a care home, a school , or a commercial office, understanding TMVs – and keeping them properly maintained – is an essential part of facilities management. In this guide, we’ll explain what TMVs do, the difference bet

TMV Valve Thermostatic Mixing Valves , commonly known as TMVs , are critical safety components in plumbing and water systems. Designed to blend hot and cold water to a safe, controlled temperature, TMVs are widely used in commercial, healthcare, educational, and residential settings. Their primary purpose is to prevent scalding injuries  while ensuring that water systems remain legionella-compliant . In this article, we’ll explain what TMV valves do, how they work, where they

When managing water systems in commercial or industrial facilities, specifying the right backflow prevention is essential. A Reduced Pressure Zone (RPZ) valve plays a crucial role in safeguarding potable water against back‑pressure and back‑siphonage contamination. This guide explains which systems require an RPZ valve, referencing UK compliance standards and practical considerations for facilities managers. What is an RPZ valve? An RPZ valve (Reduced Pressure Zone valve)

Ensuring reliable hot water for your building isn’t just a convenience—it’s essential for safety, hygiene and operational continuity. That’s why more facilities managers are choosing unvented water heaters for their buildings. These systems deliver hot water at mains pressure, without the need for a bulky cold water storage tank , offering improved performance and cleaner installs. In this guide, we’ll walk you through what you need to know to plan, install, and maintain  an

As a facilities manager, you're responsible for ensuring that every system in your building runs safely and efficiently - and that includes your hot water systems. One of the most critical components in managing water temperature safely is the thermostatic mixing valve  (TMV). But when it comes to TMV2 vs TMV3 , what’s the real difference — and which one should you be using? Let’s break it down clearly so you can make the right call for your site. What Are Thermostatic Mixing

Many people ask us about Anti-Legionella Valves , often drawn in by their eye-catching name. But do they truly prevent Legionella bacteria from growing in water systems? Let’s break it down. What Do Anti-Legionella Valves Actually Do? These valves help reduce the risk  of Legionella by promoting continuous water movement with expansion vessels , which helps to prevent stagnation—a key factor in bacterial growth. However, for some, their name implies that the valves go furthe
