Valve Flush Accessories for Toilets

Replace a urinal flush valve to fix toilet flushing problems. Valve flush parts ensure that your toilet is able to flush. Toilets that constantly run, can't flush or flush very weakly likely need a flush valve replacement. Read our guide — Common Toilet Problems — to further diagnose the situation with your toilet.

Frequently Asked Questions

Q: What Are the Different Types of Toilet Flush Valves?

A: Residential flush valves are components inside toilet tanks. They are connected to a flat, rubbery instrument called the flapper. Commercial toilets don't have tanks — instead, they have a flushometer, which is a much larger flush valve. Flushometers are easier to repair with fewer parts involved compared to regular flush valves.

Q: How Does a Commercial Toilet Flush Valve Work?

A: When the handle is pressed down on a flushometer, a relief valve inside it moves the piston to allow water to transfer from the top chamber to the bottom one. Releasing the handle allows the piston to reset, and water from the supply line is stored in the top chamber to keep a balance between both chambers so the valve can close again until the next flush.

Q: Are All Toilet Flush Valves Universal?

A: Residential and commercial flush valves require parts within the appropriate type of toilet. Aside from that, use any flush valve that's designed for that toilet type. Look for flush valve repair kits to find all the parts needed to replace or repair a broken flush valve for a toilet tank. When it comes to flushometers, the part you'll most likely need to replace is the diaphragm, which is the disc or saucer-shaped part protected by the top cover.
