Thats not a fault, it's an undocumented feature......
Actually that's very common here in NZ, possible to fix with 2 large people and a smaller person armed with packing materials, a large pinch bar may also be required.
Our current house is built on a swamp ( a long story ) and in winter the water table in the back garden is 2 inches above ground level and as the place settles the sinkbench tends to alter it's angle. ( and that's after repiling the place )
Mind you, we had a new rental house built and it took us 3 attempts to get the contractors to get the sinkbench draining in a direction that didn't include the floor.
Seem's that there are a large number of faulty spirit levels out there......
