FAQs
What is the primary use of the John Guest CI321214S fitting?
This fitting is primarily used to adapt a 1/2" Female BSP threaded connection to a 3/8" push-fit connection, commonly for drawing a 3/8" water supply from a 1/2" threaded outlet.
Is this fitting suitable for drinking water?
Yes, the fitting meets NSF standards and is WRAS Approved, making it safe and suitable for potable water applications.
What type of pipe does the 3/8" connection accept?
The 3/8" connection is designed for 3/8" Outer Diameter (OD) tubing, typically made of plastic or soft metal, that is compatible with John Guest push-fit systems.
Do I need any special tools to install this fitting?
For the push-fit side, no special tools are required, only a clean, square cut on the pipe. For the BSP connection, a wrench might be needed to tighten it onto the male thread, along with PTFE tape for sealing.
How do I ensure a leak-free connection on the push-fit side?
Ensure the pipe is cut cleanly and squarely, with no burrs. Push the pipe firmly into the fitting until it is fully seated. The internal collet will then grip the pipe securely.
What does WRAS Approved mean?
WRAS Approval (Water Regulations Advisory Scheme) signifies that the product has been rigorously tested and complies with the UK's Water Supply (Water Fittings) Regulations 1999, ensuring it is safe and suitable for use in contact with drinking water.
Troubleshooting
Fitting leaks from the BSP connection.
Ensure the BSP thread is clean and undamaged. Use appropriate thread sealant tape (PTFE tape) on the male BSP thread before connecting. Hand-tighten securely, but avoid over-tightening which can damage the fitting or thread.
Pipe pulls out of the push-fit connection.
Verify that the pipe is 3/8" OD and is pushed in fully until it reaches the internal stop. Ensure the pipe end is cut cleanly and squarely, and that the pipe material is suitable for push-fit connections. Check that the collet inside the fitting is gripping the pipe.
Water flow is restricted.
Check if the 3/8" pipe is kinked or if there is a blockage within the fitting or connected pipework. Ensure the pipe is fully inserted to avoid any internal obstruction.
