that you won't do again?

Trusted that a contractor knew what he was doing. They built me a beautiful
waterfall, but they took the pump output hose _out_ the pond, then under
the waterfall and back through the liner. Two opportunities for leaks when
they could have kept the hose inside the liner all the way. It's not just
about ponds - always supervise contractors!
