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

Extend your water tank’s life with 7 expert tips. Discover proven strategies for cleaning, inspections, corrosion control, and compliance.

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

Water Tank Relined With Polyurethane When it comes to relining water tanks , selecting the appropriate coating is crucial for ensuring longevity, safety, and compliance. Two commonly used materials are polyurethane and epoxy coatings. Each has distinct properties that make them suitable for different applications. This article aims to provide facilities managers with a comprehensive comparison to aid in informed decision-making. Understanding Polyurethane and Epoxy Coatings P

What Is a Legionella Risk Assessment? A Legionella risk assessment is a comprehensive evaluation of water systems within a building to identify and manage the risk from the proliferation of the Legionella bacteria . Legionella bacteria can cause Legionnaires' disease , a severe form of pneumonia contracted by inhaling contaminated water droplets. The assessment aims to pinpoint potential sources of Legionella growth and implement control measures to mitigate associated risks
