Common Concerns Answered
Some users report inconsistent float switch activation. How can this be addressed?
Ensure the float switch mechanism within the sump basin is free from debris and has adequate clearance to move through its full operational range. Regular cleaning of the sump basin can prevent such issues. If persistent, inspect the float switch wiring for secure connections.
Is the 3/4" outlet size sufficient for effective drainage?
The 3/4" I.D. outlet is designed for efficient greywater removal at 500 GPH. For applications requiring faster drainage or where existing plumbing utilizes larger diameters, an adapter may be necessary, though it could impact maximum flow rate.
The lid gasket can be difficult to seat properly. What is the recommended technique?
Ensure the gasket groove and the gasket itself are clean and free of any obstructions or lubricant residue before attempting to seat it. Apply gentle, even pressure around the perimeter of the lid to achieve a secure seal.
