What bravo pump did you have? I bought mine due to being highly recommended from very many sources and am very pleased with it too. It just works and is built like a tank, has good warranty and I understand, even out of warranty, distributors are able to help. But its not going to be bomb proof if its abused, like using it on a beach and sucking sand into it - that's what the kite versions are for, but with smaller inflation tubes.
But I can see if the wrong version was used, then it may well be a struggle. I needed the HP version for my floor. BST 12 HP Batt.
Hopefully not famous last words.
