The One2Flush Anti-Siphoning Fill Valve refills the tank and bowl with a minimal amount of water necessary. The key feature is the water-restricting fill valve. This red valve at the end of the fill-tube that attaches to the overflow tube regulates the amount of water that continues to rinse the bowl while the tank fills. Simply cutting back on the quart of water or more that unnecessarily rinses the bowl with each flush can save thousands of gallons of water a year.
The One2Flush water-saving fill valve fits any standard toilet on the market. It easily adjusts in height from less than 8" to fit low-profile, designer toilets of 1.6 gallons up to 12" for 3.5 gallon and larger toilets.
Each fill valve has two simple and unique features. An adjustable micro-fill valve and the removable Valve-Guard Filter that keeps debris from entering the tank or clogging the diaphragm in the fill valve. The filter is perfect for those areas of the USA that have significant amounts of calcium or other sediments that can get past water pump filters. This thimble size filter is easy to clean and rests inside the fill tube but outside the toilet tank.
