So I have very good customer for whom I've done the pond maintenance for several years. Another contractor build this pond, his first!, and while artistically it is not too bad. But construction wise, sucks big time. Short story: there is a big stream that goes into a pondless basin. All is good until the pump needs replacing. It took 2 of us 1 1/2 hours just to get the 10,000 gph pump out, not replaced. Just out! The _____ put all the connections in the very bottom of a 6 ft deep basin. He made everything as difficult and challenging as possible. Too bad I couldn't get him to replace it on his time, he might learn a lesson.
