Instead of using high-maintenance, snag-prone swing check valves in wastewater applications where modern trash is anticipated, consider using ball check valves. Ball check valves like the ones designed and manufactured by Flomatic are anti-roping and self-cleaning valves with no sharp edges or snag points, which prevents clogging from non-flushable wipes and other trash. They have been proven in wastewater lift stations for decades with a simple and reliable design with the only moving part being a vulcanized metal ball.
