Extended Product Information
FAQs
Can I use this fitting with copper pipe?
No, this fitting is designed for use with 15mm LLDPE (Linear Low-Density Polyethylene) or soft metal pipe/tubing only. It is not compatible with rigid copper pipe.
What is the maximum temperature this fitting can handle?
The fitting is suitable for intermittent hot water applications up to a maximum of 65°C.
How do I disconnect a pipe from the fitting?
To disconnect, you need to push the collet into the fitting while pulling the pipe out. It is recommended to use a John Guest push-fit demounting tool for a clean and easy release.
Can this fitting be used outdoors?
While the material is durable, it's best to protect it from direct UV exposure and freezing temperatures. Ensure proper insulation if used in areas prone to freezing.
What does 'two-way divider' mean?
It means the fitting takes one incoming pipe and splits the water flow into two separate outgoing pipes of equal size.
Is this fitting suitable for central heating systems?
This fitting is rated for potable water and intermittent hot water up to 65°C. For central heating systems which typically operate at higher temperatures and pressures, a different type of fitting designed for those specific conditions would be required.
Do I need any special tools to install this?
No, installation is tool-free. You simply push the pipe into the fitting. A demounting tool is recommended for disconnection.
Troubleshooting
Fitting is leaking
Ensure the pipe is cut square and inserted fully. Check for any debris in the fitting or on the pipe end. Verify the pipe is compatible and not deformed. Try a new fitting if the pipe or original fitting is damaged.
Pipe is difficult to insert
Ensure the pipe end is clean, square, and free from burrs. Lightly moisten the pipe end with water (not soap or lubricant) to aid insertion. Check if the pipe is the correct diameter and type for the fitting.
Fitting does not grip the pipe securely
The pipe may be too soft or deformed. Ensure you are using the correct type of compatible pipe (LLDPE or soft metal) and that it has not been previously used with other types of fittings that might have damaged it. Replace the pipe if it is suspect.
Water flow is reduced
Check that the pipe is fully inserted and not kinked. Ensure no debris is blocking the flow path within the fitting. The fitting itself is designed for superior flow, so the restriction is likely elsewhere in the system or with the pipework.
