Valves & Stop Cocks

Valves and stop cocks are designed to regulate the flow of mains water or gas in domestic and commercial plumbing systems. If a leak occurs, 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 prevent any dangerous accidents and serious structural damage to your plumbing system. 

Suitable for both internal and external fitting, most stop cocks are found under the sink, by the gas meter or in a cellar. They’re made from durable materials like brass, plastic or stainless steel, depending on the model, and come in various sizes and configurations. They’re also designed to strict British and international standards to ensure they’re reliable and robust, with a user-friendly design for convenient installation in various applications. 

We offer an extended range of valves and stop cocks here at Plumbing Superstore from leading brands like John Guest Speedfit and Hep2O. If you’re unsure which type you need, contact our excellent customer service team for advice via our helpline or live chat.
