有什么正规的赌博软件部门负责追踪防回流装置. The program works to identify all backflow devices within our jurisdiction, and to make sure 
他们每年都要接受检查.
有关回流装置的详细信息, 获取测试单, 寻找回流测试人员/承包商, 注册为承建商, 或者付款. 请致电(513)-946-7830与我们的客户服务代表联系.
回流测试表
承包商 & 房主:需要一个回流测试表? Received a backflow test sheet in the mail and lost it or want to fill it out online? 使用我们简单的在线表格!
商业回流
检查员检查商业建筑(工厂), 医院和学校)可能的交叉连接. This could potentially cause contamination of the potable (drinking) water supply. 如果发现了问题, staff work with building owners to eliminate cross connections or ensure proper installation of a backflow prevention device.
住宅回流
The residential component of this program also tracks and ensures that testable backflow devices on residential lawn irrigation systems are tested yearly.
草坪灌溉
安装和测试A.S.S.E. (American Society of Sanitary Engineers) 1013 backflow device on your lawn irrigation system you need to consider that this backflow device is capable of discharging or “dumping” a large quantity of water through the relief port, 哪些会对你的家造成损害. This “dumping” may occur if a spring loaded check becomes fouled by debris or if a backflow event occurs.
We recommend that you locate this backflow device outside where no damage can occur. 它将需要“过冬”，而不是受到冰冻温度的影响. If your device is located inside your home we recommend you contact your plumber to properly pipe the discharge to a floor drain or laundry sink capable of handling this discharge, or have the device located outside to a place of safety where “dumping” of this device will not cause harm.
2003年，一位汉密尔顿县居民被罚20美元,000 worth of damage when his backflow device “dumped” into his finished basement. This damage could have been averted if the relief port of the backflow device had been piped to a floor drain or laundry sink.
If you have any questions concerning the installation or testing of this backflow device please contact the 管道 Division at 513-946-7854 or Lisa Humble at 513-946-7851 Monday through Friday between the hours of 7:30 AM and 4:00 PM.
回流许可和检测
When a backflow device is installed by a licensed plumber, a permit must be obtained. 此后的每一年，设备必须由认证的防回流测试仪进行测试. 什么时候每年对你的防回流装置进行检测, 你会收到一封来自卫生区的提醒信.
The 回流 Test Sheet must be completed by the tester and filed in our office. 年费是25美元.
草坪灌溉系统和回流测试
Lawn irrigation systems should be tested annually to ensure they are functioning properly. 例如, 如果草坪灌溉系统上的回流装置发生故障, 动物粪便, 农药, fertilizers and other harmful substances can be back-siphoned into a water supply. This contaminated water remains in water lines until drained from another source or fixture in the home. A serious health hazard can result when contaminated water is used for drinking, 做饭或洗澡. The Ohio Basic 管道 Code requires all testable lawn irrigation backflow protection devices be tested yearly. 如果草坪灌溉系统整个夏天都在为你的院子浇水, 联系有回流测试资格的水管工进行年度检查.
什么是回流?
回流 is the unintentional reversal of the normal direction of flow in a drinking water system that may result in pollution or contamination of the system by a liquid, 气体, 固体或混合物.
When backflow occurs, the water drawn back into your main water supply may be contaminated. This contaminated water remains in water lines until it is drained from another fixture in your home. A serious health hazard could result when this contaminated water is used for drinking, 做饭或洗澡.
什么是反虹吸回流?
回来siphonage backflow is the reversal of the normal direction of flow in the piping due to a drop in supply pressure, 供应管道中的真空或负压.
我为什么要担心这个?
回流和反虹吸的情况会对你的家人的健康造成危害. When backflow occurs, the water drawn back into your main water supply may be contaminated. This contaminated water remains in water lines until it is drained from another fixture in your home. A serious health hazard could result when this contaminated water is used for drinking, 做饭或洗澡.
如何防止回流或反虹吸?
Eliminate cross connections to the drinking water supply or install a backflow device and have it tested annually. A backflow device protects drinking water from coming into contact with a questionable contaminant. 安装正确，操作正常, 它将防止污染物进入饮用水供应系统, 即使是在低压或负压的情况下.
任何机械装置都容易发生故障，必须定期检查. 要求每年对防回流装置进行检测.
通过认证的回流测试器列在电话簿中, and most plumbing and lawn irrigation companies employ a certified backflow tester. Always remember to get bids from at least three contractors before you pay someone to test your backflow device.
为什么我要付25美元.每安装或测试一台设备，收费00美元?
The $25 fee covers the cost for the Health District to track all backflow devices for Hamilton County in a computer database and on hard copy files for water purveyors and the EPA. The cost also covers the expense of mailing yearly reminder letters to our customers to have their devices tested, 而且我们经常要发不止一封信才能得到回复.
