Neutralize chlorine in water during testing or flushing without affecting flow test results or adding stress to hydrant nozzles. The Dechlor Demon uses ascorbic acid or other dechlorination agents to neutralize super-chlorinated water or regular potable water. What’s more, its short 6″ length adds no stress to hydrant nozzles. The Dechlor Demon can work within your existing testing/flowing regimen without the need for an entire new setup. It is available in NH or your thread spec.
