Product Information
Full details
The Redring Cold Water Control Pack (REDR/783101) is designed for users with medium-capacity stored water heaters, providing essential water control and pressure regulation. Its key benefit is ensuring consistent and safe operation of your stored water system by managing incoming water pressure. A potential consideration is its specific application for stored water heaters, not direct-feed systems. This pack integrates a pressure reducing valve, strainer, non-return valve, and an expansion vessel into a single, durable unit.

FAQs
What is the primary function of the Redring Cold Water Control Pack?
Its primary function is to regulate and reduce incoming mains water pressure to a safe and consistent level (3.5 bar) for medium-capacity stored water heaters, while also incorporating safety features like a non-return valve and protection against water expansion.
Is this pack suitable for all types of water heaters?
No, this pack is specifically designed for medium-capacity stored water heaters. It is not intended for direct-feed systems or instantaneous water heaters.
How often should I check the strainer?
It is recommended to check the integral strainer periodically, perhaps every 6-12 months, or sooner if you notice a drop in water pressure or flow. The frequency may depend on the quality of your incoming water supply.
What does the expansion vessel do?
The expansion vessel accommodates the increase in water volume that occurs when water is heated. This prevents dangerous pressure build-up within the stored water system.
Can I adjust the pressure reducing valve setting?
The pressure reducing valve is factory-set at 3.5 bar and is not designed to be user-adjustable. If a different pressure setting is required, a different product or additional components may be necessary.
What is included in the pack?
The pack includes the Cold Water Control unit (pressure reducing valve, strainer, non-return valve), a 2L expansion vessel, and an installation guide.
What tools are needed for installation?
Basic plumbing tools will be required, such as pipe wrenches, cutters, and potentially a pipe threading tool, depending on your existing pipework. Refer to the installation guide for specifics.
Troubleshooting
Low hot water pressure
Check if the integral strainer is blocked. Ensure the non-return valve is functioning correctly and not stuck. Verify that the incoming mains pressure is adequate.
Water hammer or banging noise from pipes
This could indicate the expansion vessel is waterlogged or incorrectly charged. Check the vessel's charge pressure (with water supply isolated) and adjust if necessary. Ensure the CWP is correctly installed according to the guide.
Leaking connections
Turn off the water supply immediately. Check that all connections are tightened appropriately and that appropriate sealing materials (e.g., PTFE tape) have been used correctly. If leaks persist, a connection may be damaged.
Water heater not filling
Ensure the main water supply is on. Check for blockages in the incoming pipe or the strainer within the CWP. Confirm the non-return valve is not obstructed.
Pros and Cons
Pros
- Simplifies installation by combining multiple components into one unit.
- Protects stored water heaters from high mains pressure.
- Enhances system safety with integrated non-return and expansion valves.
- Durable construction for long-term reliability.
- Includes comprehensive installation guidance.
Cons
- Specific to medium-capacity stored water heaters; not universally compatible.
- Requires basic plumbing knowledge for installation.
- The 3.5 bar pressure setting may not be suitable for all specific system requirements without further adaptation.
Setup, Compatibility & Care
Setup:
- Isolate Water Supply: Turn off the main water supply to the property or the specific area where the installation will occur.
- Drain Existing System: Safely drain any water from the existing pipework connected to the water heater.
- Install the Pack: Following the provided installation guide, connect the Cold Water Control Pack to the incoming mains water supply and the inlet of the stored water heater. Ensure all connections are secure and watertight.
- Connect Expansion Vessel: Verify the expansion vessel is correctly connected and pre-charged as per the manual.
- Restore Water Supply: Gradually turn the main water supply back on and check thoroughly for any leaks.
- Test System: Operate the hot water system to ensure it functions correctly and the control pack is regulating pressure as expected.
Compatibility:
- Primarily designed for use with medium-capacity stored water heaters.
- Ensure your incoming mains water pressure does not exceed the maximum rated pressure that the CWP is designed to handle before reduction.
Care:
- Periodically check the integral strainer for blockages. Access may require shutting off the water supply and partially dismantling the relevant section of the pack. Clean the strainer as needed.
- Inspect connections for any signs of leaks.
- The unit is designed for low maintenance; no regular lubrication or complex servicing is typically required beyond occasional checks.
