Claim 1:
2. The flange leveling system of claim 1, further comprising:
a second leveling unit comprising a U-shaped spring-loaded wire having a first leg with a distal end and a proximal end and a second leg with a distal end and a proximal end, and a spring connecting the proximal end of the first leg to the proximal end of the second leg and the spring acting to bias the first leg and the second leg of the second leveling unit such that the distal end of the first leg and the distal end of the second leg are biased toward each other, and a stainless steel spherical ball bearing attached to the distal end of the first leg and to the distal end of the second leg, the ball bearing of the first leg and the ball bearing of the second leg being axially co-linear relative to each other and being sized to be seated in the second plurality of angularly spaced-apart bolt holes defined in the second side of the pipe flange to mount the second leveling unit on the second side of the pipe flange.
