The MainGuard Model 77 is a leading choice for waterline flushing applications, engineered for exceptional performance, durability, and ease of service. Designed specifically to improve chlorine residual levels and remove disinfection by-products, it ensures water safety and system efficiency. Its full clear-channel valve design provides superior flow and debris passage compared to standard blow-offs, while the plunger allows for controlled throttling without causing erosion.
The unique valve design allows for a full clear-channel flow that is superior to other blow-offs for moving water and passing debris easily.
