If you’ve never heard of backflow before, it’s when the water coming from your faucet begins flowing in reverse. Backflow can compromise your water quality, but fortunately, backflow preventers typically stop this from happening. Nonetheless, it is important to get your backflow preventers checked annually to preserve the safety of your drinking water. At Manchester Emergency Plumbing, we can help customers arrange backflow testing, drain cleaning, and other routine services at any time.
