Details

The Fluidmaster PRO45B offers the ultimate solution for noisy or slow-filling toilets. This PRO Series bottom entry valve features a heavy-duty 1/2″ brass shank for a secure, leak-free connection. It replaces old-fashioned ballcocks with a modern, height-adjustable design that fits almost any cistern. We use a unique pilot-flow mechanism to ensure the valve closes instantly without “water hammer” noise. For example, you can adjust the water level in seconds to optimise your flush volume. Consequently, you get a quieter bathroom and a more efficient plumbing system.

Standard plastic-shank inlet valves often cross-thread during installation, leading to persistent leaks. Furthermore, older ballcock systems are notoriously noisy and slow to refill, often keeping the whole house awake at night. As a result, homeowners frequently deal with “ghost flushing” or cisterns that never seem to stop trickling. This Fluidmaster PRO45B Valve solves these installation and performance issues. The solid brass shank provides a rock-solid connection that won’t strip or crack under torque. Its silent-fill technology makes it one of the quietest valves on the market today. Most importantly, the height-adjustable stem ensures it fits your specific toilet perfectly, saving you the hassle of measuring or buying the wrong part.
