FAQs
What is WRAS approval?
WRAS approval signifies that the product has been rigorously tested and meets the Water Regulations Advisory Scheme standards for use with public water supplies in the UK, ensuring it is safe for drinking water and does not waste water.
Can this valve be used for gas lines?
No, this valve is specifically designed and approved for potable water systems only. It is not suitable for gas or other types of fluid.
What tools are needed for installation?
For the push-fit connection, no special tools are strictly required beyond ensuring a clean and straight pipe end. A pipe cutter, deburring tool, and a release collar for removal are recommended for a professional installation.
How do I know if my pipe is compatible with the push-fit end?
The valve is designed for 15mm copper, MDPE, and PEX pipes. Ensure your pipe is exactly 15mm in outer diameter and is suitable for push-fit connections.
What is the thread size on the other end of the valve?
The valve features a 1/2" BSP thread for connecting to compatible fittings or appliances.
How much pressure can this valve handle?
This valve is designed for standard domestic water pressures. While specific maximum pressure ratings should be checked against manufacturer specifications, it is built to withstand typical household water system pressures.
Troubleshooting
Valve is leaking from the push-fit connection.
Ensure the pipe is fully inserted and has reached the internal stop. Check the pipe end for any damage, scratches, or debris. If the pipe is damaged, cut off the affected section and re-install. Ensure the correct pipe type and size is used.
Water flow is restricted even when the valve is fully open.
Check that the valve is installed correctly and that no internal debris is obstructing the flow path. Ensure the pipe inserted into the valve is not deformed or crimped.
Difficulty removing the pipe from the valve.
Use the appropriate release collar designed for this type of push-fit fitting. Push the collar firmly against the valve body to release the pipe grip.
Valve does not fully shut off water.
Inspect the valve seating for any debris or damage. Ensure the valve has been fully actuated. If the issue persists, the valve may need replacement.
