We have a large oak barrel which we use as a WaterButt had it for a couple of years now. To be honest it as Always had a slight leak/drip which as been a pain. But since the last dry period which lasted a couple of weeks the water within was used on various plants around the house.
Then when it started raining again over the recent weekend the water runs out of the gap between several panels quicker than the butt can fill from the guttering !! I was out there in the pouring rain trying to re seat the panels without any success & it is possible to see day light between a number of panels.It is not possible to follow item seen on websites that say fill and roll barrel because the top been removed to turn into a Butt
