Most testers in Longwood can repair the device on site and re-test it the same day. Your water authority may require the passing report within a set deadline.
Cross-connection control prevents contaminated water from flowing backwards into the clean water supply. Backflow prevention devices are installed at cross-connection points to protect public health.
