Valves & Stop Cocks

Valves and stop cocks are designed to regulate the flow of mains water or gas in domestic and commercial plumbing systems. Suitable for both internal and external fitting, most stop cocks are typically found under a sink, by the gas metre, or in a cellar. In case of an unexpected leak within the system, you can use the stop cock to switch off the flow of water or gas temporarily while you resolve the issue and then switch it back on. This way, stop cocks help prevent any dangerous accidents and serious structural damage to your plumbing system. 

At Plumbing Superstore, we’re proud to offer an extended range of different types of valves and stop cocks from market-leading brands like John Guest Speedfit and Hep2O. Made from durable materials like brass, plastic or stainless steel depending on the model, our premium products also come in a wide variety of sizes and configurations. So, you’re guaranteed to find the right one for your plumbing system. 

Designed to strict British and international standards, our reliable, robust valves and stop cocks are easy to install and maintain, making them a highly convenient solution for various applications.  

Don't forget these when installing valves and stop cocks for your latest project:
