Can I send my LPG Freeze Valve AT-1000 to RSC for repair and/or calibration?

The AT-1000 LPG Freeze Valve can be repaired and/or calibrated per the manufacturer’s specifications. Once your valve is received it will be analyzed and an evaluation form will be sent to you. This form will provide the repair cost and a replacement cost of a new unit for comparison. Please note: If you do not choose to repair or replace a unit, and decide to have the unit scrapped or returned as is, you are still responsible for a $350 analysis charge.
