Collapsible Water Storage Tanks

Temporary Water Storage for Hot Tub Servicing

Hydrostar Onion TankCollapsible water storage tanks, such as the Hydrostar Onion Tank by GEI Works, are an industry favorite for temporary water storage when repairing, refurbishing, cleaning or servicing hot tubs. Durable and dependable, onion tanks require virtually no set-up, and rise as they fill. They empty just as easily, with a built in port at the base for convenient drainage. When not in use, onion tanks fold up tightly for storage and easy transportation.

Self-Rising Onion Tanks for Hot Tub Temporary Water Storage

Better, faster, and safer than inflatable water tanks for hot tub cleaning or servicing, Onion Tanks are self-rising and stable. Simply lay the tank out on a flat area. Place the end of the hose in the top opening of the onion tank, and power the pump to suction the water from the hot tub to the tank.

Unlike with inflatable water tanks that require additional set up time and effort, Hydrostar Onion Tanks are self-rising. As the water enters the tank, the walls of the tank rise on their own, safely containing the water from the hot tub. It fills within minutes with little to no intervention, allowing fast access to the hot tub for the job at hand. This saves time and effort, making it a perfect solution for hot tub cleaning services, repair and refurbishing operations.

A Collapsible Water Storage Tank for Use Again & Again

Storing the Onion TankAfter the hot tub cleaning services or repairs have been completed, there's no need to spend the time and money in treating new water again. Simply refill the hot tub with the water saved in the Hydrostar Onion Tank.

Refilling the tank couldn't be easier. Once the hot tub's servicing is done and it's time to empty the tank, simply hook the hose and pump in reverse to the port at the base of the collapsible water storage tank. Unlike inflatable water tanks that require extra time and effort in deflating the tank, the Hydrostar Onion tank collapses on its own as it empties. Once empty, simply fold the tank back up for easy storage, and use it again another day.
