Flexi Tank Collapsible Fold Up Compact Hydroponics Grow Water Butt Storage (100 Litre)

Does the lid lift off so i can pour water inside?

Can this product be erected and collapsed multile times and with ease ? So for example to use it , collapse it, transport it elsewhere erect it again

Does the tap connect to a hose/pressure washer?

how does it collect the water? does it have to be attached to down pipe? i am looking for a stand alone water barrel collecting rain water as it falls
