Product Information
Full details
This JG Speedfit Brass Manifold is for plumbers and DIY enthusiasts needing to efficiently split a main water supply into multiple outlets. Its key benefit is a significantly faster, tool-free installation compared to traditional methods, ideal for confined spaces. A primary caveat is its unsuitability for central heating systems. The manifold allows for secure, push-fit connections for 15mm pipe and 3/4" outlets, centralizing water distribution and simplifying plumbing layouts.

FAQs
What types of pipe can I use with this manifold?
This manifold is compatible with 15mm copper pipe, JG Speedfit PEX pipe, and JG Speedfit polybutylene pipe. For plastic pipes (PEX and polybutylene), you must use the appropriate JG Speedfit pipe support inserts.
Can this manifold be used for central heating?
No, this manifold is *not* suitable for central heating systems. It is designed for hot and cold water services only.
How do I connect pipes to the manifold?
Simply push the pipe (prepared with an insert if plastic) firmly and squarely into the 15mm push-fit socket until it reaches the internal stop. The connection is instant and secure.
How do I remove a pipe from the manifold?
To demount, push the blue collet towards the body of the fitting and simultaneously pull the pipe out. No tools are required.
Does this manifold come with adapters for the 3/4" outlets?
The manifold itself has 3/4" BSP threaded outlets. You will need to purchase appropriate 3/4" BSP fittings or adaptors separately depending on what you are connecting to the outlets (e.g., hose connectors, threaded pipe).
Is this manifold suitable for use in confined spaces?
Yes, the push-fit system eliminates the need for tools and hot works, making it an excellent choice for installations in tight or hard-to-reach areas.
What is the maximum number of outlets?
This is a 4-port manifold, meaning it allows you to split the main supply into up to four separate outlet feeds.
Troubleshooting
Manifold leaks after installation
Ensure the pipe was pushed fully into the fitting until it stopped. Check that the pipe end is clean, square, and free from damage. For plastic pipes, verify the correct Speedfit insert was used and fully inserted. Demount and re-install the pipe connection.
Pipe is difficult to insert
Check that the pipe end is not deformed or damaged. Ensure the correct size pipe and fittings are being used. Slightly moisten the pipe end with water (not lubricant) to ease insertion if necessary, then push firmly and squarely.
Pipe will not release from the fitting
Ensure the blue release collet is being pushed firmly and squarely towards the body of the fitting. Make sure there is no debris or damage preventing the collet from retracting. Try gently twisting the pipe while pushing the collet.
Water flow seems reduced
Check that the manifold is fully open and that all connected pipes are not kinked or obstructed. Ensure there are no blockages within the manifold itself, though this is rare with clean water systems.

Setup, Compatibility & Care
Setup:
- Ensure the pipe ends (copper, PEX, or polybutylene with inserts) are clean, free from burrs, and cut square.
- For plastic pipes, insert the appropriate Speedfit pipe support insert fully into the pipe end.
- Push the pipe firmly and squarely into the manifold's push-fit socket until it reaches the internal stop. You should feel a positive engagement.
- To demount, push the blue collet towards the body of the fitting and simultaneously pull the pipe out.
Compatibility:
- Pipe Types: Compatible with 15mm copper pipe, JG Speedfit PEX pipe, and JG Speedfit polybutylene pipe (when used with appropriate Speedfit inserts).

Care:
The brass manifold requires minimal care. Periodically check connections for any signs of leakage. If cleaning is necessary, use a soft, damp cloth. Avoid abrasive cleaners or solvents, which could damage the nickel plating or internal seals.
