The Thomas Dudley Part 2 Float Valve Replacement Arm is designed for DIY homeowners and plumbing professionals seeking a reliable, 8-inch replacement component for standard float valve systems. Its primary benefit is the restoration of proper water level control and flow, though it is specifically sized for standard Part 2 valves and may not fit unique or proprietary high-pressure cistern setups.

It is designed for standard Part 2 float valves. It is recommended to compare it with your current arm before installation.
No, this product is the replacement arm only; the float ball must be transferred from the old arm.
Measure the length of your current arm. This unit is specifically 8 inches in length.
Typically, only an adjustable wrench or pair of pliers is needed to tighten the arm onto the valve.
The material is chosen for its durability in water, though lime scale buildup should be cleaned periodically to prevent degradation.
Adjust the angle of the float arm downwards to shut off the valve earlier.
Ensure the arm is threaded fully into the valve and the lock nut is tightened firmly.
Check that the arm is not bent and is allowing the valve to open fully.
To install, first isolate the water supply to the cistern and flush to empty the tank. Unscrew the existing arm from the valve body and remove the float ball. Align the new 8-inch arm, ensuring it is securely fastened to the valve threads. Reattach the float ball, then adjust the arm angle if necessary to ensure the water level stops approximately 1 inch below the overflow pipe. For care, periodically check for lime scale buildup on the connection point, which can be cleaned with a mild descaler to ensure smooth movement.
