YOUR QUESTIONS ANSWERED
Does My DayTank Include a Mount?
No, the WaterPORT tanks do not come with a mount included. Mounts may be purchased separately on our site. The DayTank includes a back u-bracket.
How Should I Store My DayTank to Prevent Bacteria Buildup?
Your DayTank should be rinsed with soap and water. If the tank is not used for drinking, you may add 2-3 drops of bleach. Make sure the top cap of the tank is left off so the tank can properly dry out before use.
Can I Put Boiling Water in My DayTank?
You can definitely add hot water, but we don't recommend boiling. You don't want the steam to mess with the pressurization in the tank.
How Can I Prevent My DayTank from Getting Stolen?
The DayTanks mounting plate allows for a pad lock to be placed through the top hole.
