Commercial Skimmer Minimum Fill Line Details

The skimmer on the tub has an engraved minimum water line. 

It is important to keep the water level a half an inch to an inch above the minimum water line. If it falls below the minimum water line, air can enter the system and if left unattended can lead to damage and void your warranty.

The Plunge will arrive with the ball valve to the skimmer closed and the skimmer suction off. We recommend not turning it on until you fully understand the water displacement for your tub and bather load.
If you find you can easily keep the water above the minimum line, then please read the following directions on how to turn the skimmer suction on. 

1. Open the vent on the side with the main tub drain. 
2. You should see the side of the electrical box and if you look past it you’ll notice a colored ball valve. It should be perpendicular to the piping indicating it’s closed. 
3. Turn the valve parallel to the piping and the skimmer suction will turn back on. 

Please do not turn the suction on if you cannot keep the water level above the minimum line consistently.

We recommend you check the water level throughout the day and make sure to refill the tub before closing in the evening.
