what is backflow testing
Itâs also a good idea for residential homes to periodically have backflow testing conducted. This is especially true of older homes which often do not have an adequate backflow prevention device installed. In many cases, the Water and Sewer Department will contact you and require you to have your backflow tested. This isnât cause for alarm. Backflow testing is a routine procedure which is designed to make sure that no contaminated water is entering your water supply from outside sources.
