Add a serviceable one-way valve to a compatible return line. The clear body makes the swing mechanism easier to inspect, while union ends allow the valve to be removed for cleaning. Select the nominal slip PVC size that matches your pipe.
- Available in 3/4 in and 1 in slip-union sizes.
- Install in the indicated flow direction and follow the valve's orientation requirements.
- Check valves require periodic inspection and cleaning. Keep adequate sump capacity for backflow if power fails; do not rely on a check valve as the only flood safeguard.
