The Dudley Tetra Side Entry Inlet Valve is designed for homeowners and professional plumbers seeking a dependable, long-lasting solution for toilet cistern maintenance. Its primary benefit is the self-compensating mechanism that maintains consistent performance across fluctuating water pressures, ensuring a quiet and fast shut-off. While it is built for durability and ease of installation, users should verify their existing arm configuration, as this unit is specifically engineered to be compatible with 210 and 231 arms.

No, the Dudley Tetra is specifically designed as a side-entry inlet valve.
No, this valve is specifically compatible with 210 and 231 arms.
Yes, its smooth shut-off mechanism is designed to reduce the risk of water hammer associated with sudden valve closures.
If properly installed, the valve is built for longevity and should only be replaced if you experience persistent leaks or mechanical failure.
Typically, an adjustable spanner or a pair of water pump pliers is sufficient to secure the mounting nut.
Check the float level adjustment or ensure the arm is not obstructed by the side of the cistern.
Inspect the inlet nozzle for mineral deposits or debris and clean if necessary.
Verify that the inlet pipe is secure and the water pressure is not excessively high, which may require a pressure reduction valve.
To install, ensure the water supply is isolated before removing the existing valve. Align the unit with your existing 210 or 231 arm, ensuring the connection is secure and leak-proof. Do not overtighten the plastic threads, as this may cause cracking. Regular maintenance involves checking the diaphragm for debris if water flow slows down significantly over time. Ensure the float arm is positioned so it does not rub against the sides of the cistern wall, as this can prevent the valve from closing properly.
