Broken Cooler

[Gardenboy]

Hi everyone! I have a water cooler. The tank beneath is cracked and is leaking water. It is made up of plastic type of stuff. Any good product recommendations or ideas to seal the plastic?

I need some durable ideas as it holds a lot of water. Any temporary fixes might not hold up for long due to the weight of the water.

Thank you in advance!

Do you have any pictures? What brand is it? Water coolers are built in many different ways so it probably matters how it is configured.
