MDPE Stop Taps for Underground Water Mains
MDPE stop taps are commonly used to isolate water supplies in polyethylene pipe networks. They provide a convenient connection to compatible metric MDPE pipe and are widely installed on incoming water mains, agricultural water systems and underground distribution networks.
Compression stop taps allow connections to be made without solvent welding or heat fusion, making them suitable for new installations, repairs and alterations to existing water pipework.
When selecting an MDPE stop tap, ensure the fitting matches the outside diameter of your polyethylene pipe and is suitable for the required operating pressure.
Brass & Gunmetal Water Stopcocks
Our range of brass and gunmetal stop taps provides traditional water isolation solutions for domestic, commercial and industrial pipework.
Brass stopcocks are widely used in plumbing and water distribution systems, while gunmetal stop valves provide a durable alternative for applications requiring robust metal-bodied fittings.
Available with different connection arrangements, these valves are suitable for controlling water flow and isolating sections of pipework for maintenance.
WRAS Approved Stop Taps
For drinking water installations, selecting suitable water fittings is essential. Our collection includes WRAS approved stop taps designed for use in potable water supply systems.
WRAS approval provides independent evidence that an approved product meets relevant requirements for water fittings. Always check the individual product listing to confirm its current approval status, permitted applications and installation requirements.
Typical Applications

Choosing the Correct Mains Stop Tap
When selecting a water mains stop tap, consider the pipe material, outside diameter, connection type, operating pressure and installation location.
For MDPE water pipes, compression stop taps provide a convenient mechanical connection. Push-fit stop taps offer an alternative for compatible pipe systems, while brass and gunmetal stopcocks are commonly selected for installations requiring metal-bodied valves.
For underground installations, ensure the valve is suitable for below-ground use and installed in accordance with the manufacturer's recommendations.
