Description
The MainGuard #78 Blow-Off installs underground in a standard meter box. Designed and engineered specifically for flushing, the #78 provides excellent flow rates for improving chlorine residual levels and flushing disinfection byproducts (DBPs) to keep water safe for consumers. Its unique valve design allows for a full clear-channel flow (see illustrations) that is superior to other blow-offs for moving water and passing debris easily. The #78 plunger is also designed to allow for throttling the flow of water while at the same time covering the drain hole to avoid unnecessary erosion. The MainGuard #78 is fully serviceable from above ground.
The MainGuard #78 comes standard with:
- All brass principle working parts
- Nozzle sizes up to 2 ½” NST
- Traffic break-away
- Self-draining
- Non-freezing
- 2” FIP vertical (straight) inlet
- Locking security cover
- Certified to NSF/ANSI 372
