You Can Keep Your Tanks Full After Installing Mixing or a Trihalomethane (THM) Removal System
Many systems rely on deep draw downs, low tank levels, and flushing to break temperature stratification and keep trihalomethanes from becoming more of a problem. This can prove useful for the short term but it isn’t a very reliable long term water quality solution. It can also leave your system seriously vulnerable in emergency situations such as fire protection and service disruptions ...
