Plasson Stop Tap - 3/4" BSP

'FI x FI' stands for Female Iron x Female Iron. This means both ends of the stop tap have internal threads designed to screw onto external (male) threaded pipes or fittings.

While plastic construction offers corrosion resistance, the suitability for hot water depends on the specific plastic's temperature rating and the water temperature. For high-temperature applications, a metal tap might be more appropriate. Consult product specifications for exact temperature limits.

This stop tap is primarily designed for water applications. Using it with compressed air may be unsafe and void any warranty, as compressed air systems often have different pressure and material requirements.

BSP threads are common in the UK and many Commonwealth countries. 3/4" refers to the nominal size of the pipe. You can measure the outer diameter of the male thread (it will be slightly larger than 3/4 inch) or compare it to known BSP fittings.

With proper installation and standard water usage, the durable plastic construction offers excellent longevity and resistance to corrosion, typically outlasting metal taps in environments prone to rust.

Due to its corrosion resistance, it can withstand burial. However, ensure the connection points are protected and accessible for maintenance. It's recommended to check local plumbing codes regarding buried valves.

Ensure the 3/4" BSP threads on both the tap and the pipe/fitting are clean and undamaged. Tighten the connection further, but do not overtighten. Consider using PTFE tape or pipe sealant on the male threads if the leak persists.

Check for any debris or sediment within the tap mechanism. Operate the tap fully open and closed a few times. If the issue persists, the tap may need to be replaced.

Ensure there are no obstructions in the pipework leading to or from the tap. Check if the tap was fully opened. If the tap is new, inspect the internal mechanism for manufacturing defects.
