FAQs
What does 'Part 2' mean for this float valve?
'Part 2' typically refers to a specific design standard or type of float valve, often indicating its mechanism or how it's intended to be installed within a system. This specific valve is designed for high pressure and quick response.
How do I confirm if I need the 3/4 Inch or 1/2 Inch valve?
Measure the outer diameter of your existing male thread. A 3/4 Inch BSP thread measures approximately 1 inch (around 25mm) in diameter. If your thread measures roughly 3/4 inch (around 19mm) in diameter, you need the 1/2 Inch version.
What is the maximum pressure this valve can handle?
This high-pressure float valve is rated for a maximum of 16 bar.
Can this valve be used in potable water systems?
Yes, the product is described as anti-corrosion and suitable for use with recycled water, implying suitability for potable water systems as well, provided local regulations are met.
Does the valve come with any installation instructions?
While specific instructions are not provided here, standard installation involves connecting it to the water supply inlet of a tank or cistern. It's recommended to consult a professional plumber if you are unsure.
What is the temperature range for this valve?
The valve is suitable for use under high temperatures, though a specific maximum temperature is not detailed in the product information.
Is this valve suitable for a standard home water system?
Yes, if your home water system operates at high pressure and requires reliable water level control, this valve is suitable. Always confirm your thread size.
Troubleshooting
Valve is leaking after installation
Ensure the valve is tightened correctly. Check the sealing tape on the threads for proper application and consider re-applying if necessary. Verify the thread size compatibility.
Water level does not shut off completely
The valve may be obstructed by debris. Turn off the water supply, remove the valve, and clean the internal mechanism. Ensure the float arm is correctly positioned and not binding.
Excessive noise or hammering persists
While the valve helps reduce water hammer, other system issues might contribute. Ensure the valve is functioning correctly and consider checking water pressure in the system. Ensure the float arm is not set too high, causing premature shut-off.
Valve fails to open or close
Check for blockages within the valve or the water supply line. Verify that the float arm is moving freely and is correctly adjusted. If the problem persists, the valve may need replacement.

Setup, Compatibility & Care
Installation:
- Identify Thread Size: Confirm your existing thread diameter. Remember, a 3/4 Inch BSP thread measures approximately 1 inch (around 25mm) in outer diameter. If your measurement is closer to 3/4 inch (around 19mm), you need the 1/2 Inch version.
- Turn off Water Supply: Ensure the main water supply to the installation point is completely shut off.
- Remove Old Valve: Unscrew the existing float valve.
- Install New Valve: Screw the Primaflow valve into place, ensuring a secure fit. Use appropriate sealing tape (like PTFE tape) if required for your specific plumbing setup.
- Turn on Water Supply: Slowly turn the main water supply back on and check for leaks.
Compatibility:
- Designed for high-pressure water systems (up to 16 bar).
- Compatible with systems operating at high temperatures.
- Suitable for use with recycled water.
- Requires a 3/4 Inch BSP thread connection (which measures approx. 1 inch in diameter).
Care:
- Periodically check the valve for any signs of wear or debris.
- If performance degrades, gently clean the valve mechanism without harsh chemicals.
- Ensure the water supply is turned off before attempting any maintenance.
