I ordered 4 rectangular butts which were to be Daisy-chained together and replace 4 Graf water butts 12 years old whose tie-bars had rusted away. The bulged a water overflowed in the wrong places. Delivery took slightly over a week and 3 packages were damaged. It turned out that 2 butt stands could not be used. I reported and these were replaced quickly 4 days later. When I started assembling it turned out that one butt had a crack which opened when filled with water. Another butt started cracking where i drilled hole for tap and lost all its water overnight, A third started two cracks around the butt connector hole. The old butts had no cracks after 12 years1 I think that material must be sub-standard. I have requested a refund for whole order and await a reply as only 1 butt is usable and for how long is unknown.
