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.
