Fluidmaster® is the #1 toilet parts brand in the world, selling more than 100 million toilet products annually and selling more toilet-tank replacement parts than any other manufacturer in the world.

All our products are backed by an industry-leading warranty and come with an assurance of excellence from the world’s leading toilet parts company. In the U.S., 90% of the new toilets sold have a Fluidmaster fill valve installed in it. Toilet manufacturers like Kohler, American Standard, Glacier Bay and Mansfield install Fluidmaster fill valves in their new toilets.

Fluidmaster’s success began with the desire and drive of our founder Adolf Schoepe. Convinced that the existing toilet technology was inefficient and unreliable, he wanted to create a more advanced fill valve that worked with, rather than against, water pressure. In 1957, Mr. Schoepe’s vision became a reality when he revolutionized the toilet parts industry by launching Fluidmaster’s innovative pilot fill valve technology.

Today, Fluidmaster has become the most trusted name in toilet parts both by the DIY customer and plumbers. Our Technical Support team helps thousands of customers every year fix their toilet problems who give us high praise for our customer service. We are dedicated to providing the best support to our customers.
