What is a service valve?

A service valve is an essential device in any modern plumbing system. It is a valve that controls the water flow in a specific section of a pipe network. Unlike the main valve that shuts off the supply for the entire property, the service valve offers more precise and localized management. Its utility is crucial for upkeep and maintenance of hydraulic installations, as it allows isolation of a part of the network without affecting the rest of the system. This feature is particularly appreciated during repairs or equipment replacements, thus avoiding depriving an entire dwelling or building of water.

Types of service valves

There are several types of service valves, each adapted to specific needs:

• Ball valve: Very common for its reliability and ease of use
• Quarter-turn valve: Quick to manipulate, ideal for emergency interventions
• Gate valve: Allows progressive flow control, but slower to close
• Butterfly valve: Often used in industrial installations

The choice of service valve type depends on several factors, including network pressure, expected frequency of use, and available space for installation. Ball valves and quarter-turn valves are particularly appreciated in domestic installations for their simplicity of use and efficiency. In all cases, it is crucial to select a quality model to ensure optimal longevity and avoid potential leaks.

Installation and strategic placement

Installing a service valve requires consideration of its location to maximize its utility. Ideally, it should be placed at strategic points in the plumbing network, such as:

• Before each important sanitary fixture (toilets, sink, shower)
• At the entrance of different water rooms (kitchen, bathroom)
• On main pipes serving different floors or areas of a building

A judicious installation not only facilitates maintenance interventions but also limits damage in case of localized leaks. It is recommended to call a professional plumber for installation to ensure compliance with current standards and avoid any risk of leakage. The accessibility of the valve is also an important criterion to consider during installation. It must be easily reachable, even in confined spaces, to allow quick manipulation in case of emergency.

Maintenance and lifespan

Although robust, service valves require minimal maintenance to ensure their proper functioning over the long term. It is recommended to manipulate them regularly, at least once a year, to prevent them from seizing up. This simple action allows checking their proper functioning and preventing potential problems. In case of leakage or malfunction, it is preferable to replace the valve rather than attempt a repair, especially if it is old. The average lifespan of a quality service valve can reach several decades if properly maintained and used. Investing in superior quality models can prove economical in the long run, reducing the risks of leaks and the need for frequent replacements.
