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

A cold-water storage tank, sometimes called a header tank or cistern, is a container that stores water for later use. In most commercial and residential buildings, it provides a steady supply when the mains supply is interrupted, when pressure drops, or when large volumes are needed quickly. Facilities managers rely on these tanks to keep water available for daily use, safety systems, and to ensure compliance with hygiene regulations. How does a cold-water storage tank work i

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)

For facilities managers responsible for the upkeep of commercial or industrial buildings, water storage maintenance is a constant balancing act between cost, safety, and regulatory compliance. Over time, even the best-designed cold water storage systems begin to show signs of age - from internal corrosion to leaks and general wear and tear. When this happens, the question naturally arises: Should you reline the tank or replace it altogether ? In this guide, we’ll walk you th

As a facilities manager, you know how important water hygiene compliance is - not just for ticking boxes, but for protecting the health of your building users. If you’ve recently had a Legionella risk assessment, you may be looking at a list of recommended remedial works. The big question is: do you tackle just the high-risk items now, or sort the entire system in one go? This guide explores the pros and cons of both approaches to help you decide which is right for your site.

Pair of flexi hoses under a sink The Overlooked Risk Inside Flexi Hoses Flexible braided hoses, or flexi hoses, are a familiar sight in commercial plumbing. Whether they’re used to connect sinks, taps or appliances, their flexibility and ease of installation make them a popular choice. However, what many facilities managers don’t realise is that the very materials inside these hoses can create the perfect environment for Legionella bacteria to grow. Legionella pneumophila, t

Installing a cold water tank is a critical task that, if done incorrectly, can lead to significant operational issues, compliance failures, and costly repairs. Facilities managers must ensure that installations meet both functional requirements and regulatory standards. This article outlines nine common mistakes to avoid during water tank installation , helping you maintain system integrity and compliance. 1. Uneven Base Installation A level base is fundamental for the struc

COVID-19 has changed how commercial buildings are used. While full closures were a short-term disruption, the long-term shift toward hybrid and remote working has resulted in a quieter, less consistently used built environment. For facilities managers, this poses a subtle but serious problem: water systems that are underused or intermittently operated can become breeding grounds for Legionella bacteria . Understanding this ongoing risk and how to manage it is now more importa
