If water is backing up or draining slowly at the Mini, work through these checks.
- Check for kinks in the drain line.
- Ensure proper slope (minimum 1/4" per foot).
- Verify the unit is properly seated and sealed.
- Check for clogs downstream from the unit.
- Use the maintenance flush port to clear any blockage at the unit.
- When clearing the line with air, check for a P-trap in the system. After the air flush, refill the P-trap with water to restore the water seal.
