 Warm Tips

1. Don’t over tighten the faucet adapter since it is made of plastic.
2. Turn off the valve on the gravel tube before turn on the faucet.
3. Empty water out of gravel tube before storing it, or it may get mildewed.
4. If you want to vacuum with acceptable suction, you need to fully open the faucet. To save water, you can turn off faucet once you have a stable vacuum. However, gravel cleaning requires the faucet fully open.
5. If the faucet has a sprayer or filter head, you need to unscrew that before screwing the connector onto the faucet.
6. When you are draining the water from the tank, the water flow assembly valve should be open. Please close the vacuum tube valve at first. After you open the faucet, you can open the vacuum valve.
7. The sink you are using should be level with or lower than the tank.
