For easy pipe flushing of a pipiline section after removing the ARV from H-TEC Automatic Air and Vacuum Release Valve Sets or ARV with shut-off for manhole installations of the H-TEC Model #986.
No bending into the manhole shaft.
Dual use increases efficiency:
- ARV location that eliminates confined space entry
- Entry point for flushing and cleaning
