Extended Product Information

FAQs

What size is the thread on this float?

This float features a standard 5/16-inch thread.

Is this float suitable for saltwater?

The float is designed for general water applications; however, long-term exposure to harsh chemicals or extreme saline conditions is not recommended.

Can I use this with a 1-inch valve?

No, this float is specifically designed for 1/2-inch and 3/4-inch BSP float valves.

Does the color serve a purpose?

The red color helps with high visibility, making it easier to locate the float inside opaque tanks or murky pond water.

What should I do if the float gets punctured?

If the float is punctured, it will fill with water and lose buoyancy. It should be replaced immediately to ensure the valve continues to function correctly.

Troubleshooting

Float is not shutting off the valve

Check if the float has taken on water through a crack or puncture and adjust the valve arm height if necessary.

Float sits too low in the water

Verify there is no excessive algae or debris accumulation on the surface of the float that is weighing it down.

Float is loose or wobbling

Check that the 5/16-inch thread is fully engaged and the plastic lug is not stripped.

Pros and Cons

Pros

  • Cost-effective solution for water level control
  • Lightweight design reduces stress on valve arms
  • Easy to install without specialized tools
  • Compatible with common plumbing valve sizes
  • Resistant to corrosion and water damage

Cons

  • Plastic material may be susceptible to heavy impact damage
  • Not suitable for high-pressure industrial chemical applications
  • Limited to specific 5/16-inch threaded connections

Setup, Compatibility & Care

To install, ensure your valve arm has a 5/16-inch thread to match the float. Simply screw the float onto the end of the valve arm until it is hand-tight. Do not overtighten, as this may strip the plastic threads.

Compatibility: This unit is specifically compatible with valves accepting 5/16-inch threads and is intended for use with 1/2-inch and 3/4-inch BSP systems.

Care: Regularly inspect the float for surface debris, algae growth, or calcium build-up, which can add unnecessary weight and cause the valve to stick. Clean periodically with a soft cloth and mild soap. Ensure the float is free from punctures or cracks, as water ingress will cause the float to lose buoyancy.
