TBH-Z's vent hole exists because a standard ball valve traps sodium hypochlorite in its cavity, where it off-gasses and crystallizes — a documented ball-valve failure mode in wastewater chlorine-feed service, per Hayward's own design rationale.
Municipal wastewater lines carry both raw sludge duty (where AVCO's economy 316SS 100 Series is a defensible low-cost shutoff) and chlorine-feed duty (where a standard ball valve's un-vented cavity is a crystallization failure waiting to happen) — treating both service points as 'just a ball valve' is how the wrong one ends up on the wrong line.
