The FloPlast Plastic Stopcock 25mm MDPE is an essential plumbing component designed for professional contractors and DIY enthusiasts who need to control water flow in cold water service lines. Its primary benefit lies in its high-impact, durable co-polymer polypropylene construction that ensures a secure, leak-free shut-off for both above and below ground applications. While it offers excellent durability for cold water systems, users should note it is strictly intended for cold water use and is not suitable for hot water or high-pressure heating systems.

No, this product is specifically engineered for cold water service lines only.
Yes, the co-polymer polypropylene construction is designed to withstand the stresses of both above and below ground installations.
The stopcock is tested to a maximum pressure rating of 16 bar.
Yes, the unit includes the integrated nut and grip mechanism required for a 25mm MDPE connection.
No, this component is designed specifically for MDPE (Medium Density Polyethylene) pipe.
It operates effectively within the temperature range of -10°C to +45°C.
Check that the pipe is inserted fully past the O-ring and that the nut is tightened securely. Ensure the pipe end is not scratched or damaged.
Check for mineral deposits around the valve stem. Gently flush with clean water or use a food-safe silicone lubricant if necessary.
Verify that the threads are aligned correctly. Never force the nut if resistance is felt, as this may indicate cross-threading.
To install, ensure the 25mm MDPE pipe is cut cleanly with a plastic pipe cutter. Slide the nut and grip ring onto the pipe before inserting it fully into the stopcock body. Tighten the nut firmly by hand, followed by a light turn with a wrench if necessary, taking care not to overtighten and crack the plastic components. The unit is compatible with all standard blue or black 25mm MDPE piping. For maintenance, periodically turn the handle to prevent lime scale buildup in hard water areas. No lubrication is required, but ensure the area around the stopcock remains free of debris for easy access during emergencies.
