Frequently Asked Questions
Q. "What is the difference between a flushometer and flush valve?"
A. A flushometer is a metering valve for commercial toilets and urinals. Basically, a flushometer is a commercial flush valve. A flush valve is a component in a tank style toilet.
Q. "Is there anything to be aware of when using high volume flush valves on low consumption china?"
A. Yes, be careful when using high volume flush valves on low consumption china. The higher pressure and shear volume may vent thru the vacuum breaker assembly. If so, then use the V651 vacuum breaker repair kit instead of the V551 vacuum breaker repair kit. When using the shut-off valve screw as a throttle, you also upset the balance of the valve and its self-cleaning feature. The rubber bumper on the back-check stop will also wear much faster as it is spring loaded and you will be forcing it closer to the seat, then throttling the valve. Flush valves that are throttled require more conditioning and attention because they often foul more frequently. The opposite would also apply when using a 1.6 gpf on a 3.5 gallon flush toilet.
Q. "Do you sell the Sloan Flushmate tank/valve combination?"
A. We have never sold or recommended the Sloan Flushmate tank/valve combination nor do we sell parts for them.
Q. "How does a Sloan valve operate?"
A. A Sloan valve works by equalizing pressure in the chambers over and under the diaphragm. Basically, the water will run until the top chamber is filled. This is the 'flow timing;' you can adjust the timing with a 'flow-ring.' A flow-ring is the plastic ring directly under the diaphragm. Sloan and Zurn both make flow rings in 1.0, 1.6, 3.5 and 4.5 gallons per flush designations.
Q. "What is a 'dual flush' valve?"
A. Dual flush valves give the user the choice of flushing with the maximum amount of water allowed by law (1.6 gpf in the United States) or a flush that uses less water.
Q. "What is a squat toilet?"
A. A toilet that is used by squatting instead of sitting. They are widely used in China, Japan, and South East Asia.
