Usually a water system can maintain adequate pressure to keep the water clean and flowing in the right direction. Sometimes, in the case of main breaks or burst pipes or other situations that create a large drop in pressure within the system, contaminated or dirty water can reverse direction and flow back into the system. That’s why a backflow prevention program is vital, from single family residence to pumping station, and we stock and supply a variety of preventative solutions to keep your water clean and flowing forward. We stock up to 2” double check and reduced pressure zone devices by Wilkins, as well as dual checks and pressure regulators. We can also get any larger device to go in your meter vault installation or fire suppression line. Just call and ask.
