Adjust the flow rate of the water per the manufacturer’s instructions. If the flow is quicker than the drainage rate of the separator, water will accumulate in the tub and overflow once the tub is filled. Consult the owner’s manual for the separator’s recommended water flow rate.
Open the drain valve and drain the separator.
Inspect the drain valve and clear it of any obstructions.
Remove any visible dirt and debris. Clean the separator with soap and water. Clean the separator a minimum of every six months.
