Nicholson Lab Inc.

Nicholson Lab, Inc. has been serving the backflow industry since 1990, providing factory recalibrations and replacement parts for a wide array of test equipment.  Specifically, Nicholson Lab is the factory-authorized recalibration center for the widely popular Watts line of backflow preventer test kits.  This would include the 9A, 99E, TK-DP, TK-DL, and TK-99D.  In addition to these testers, Nicholson Lab is also capable of repairing and recalibrating many other backflow devices.  All of our recalibrations are performed on GE Druck instruments.

We also can provide factory original replacement parts, any necessary literature, or testing accessories that you may require.  We also coordinate the buying selling and trading of new, used, and rebuilt backflow gauges.  For more information, please call Nicholson at (513) 251-8378.
