Frequently Asked Valve Questions

If would like to know more, please get in touch and we’ll be happy to answer your questions.

The water industry uses a broad range of valve types. Gate, butterfly, check, and ball valves are most common. Each has unique features suited for specific functions like regulating flow, preventing backflow, or isolating sections of the system.

Consider water flow rate, pressure, size, and material compatibility with the fluid. Factors like the system’s operational environment and maintenance requirements also play a crucial role.

Regular inspection, cleaning, and lubrication are key. Frequency depends on the valve type and system conditions. Following the manufacturer’s guidelines is essential for optimal performance and longevity. Valves can be swapped out in regular maintenance programs.

Common issues include leaks, blockages, or wear. Regular checks for unusual noises, leaks, or operational inefficiencies can help identify problems early. If you are unsure, please contact us for advice.

Yes, certain water valves are designed for high-pressure environments. These usually have robust construction and special sealing mechanisms to handle the increased stress. Each valve is tested to the toughest criteria.

Many valve types can be repaired, depending on the extent of damage. However, severely damaged or outdated valves may require replacement. John valves have been repairing valves for the industry for decades and have the skills and knowledge. 


Choose water valves that minimise leakage and are made from sustainable, corrosion-resistant materials. Also, consider valves that facilitate energy-efficient operation.


Look for certifications like ISO, or water industry standards relevant to water and wastewater applications, ensuring safety, quality, and compliance.

Correct sizing is crucial for effective water flow control and system efficiency. Oversized or undersized valves can lead to issues like cavitation, flow turbulence, or increased wear.
