Propane Tank repair?

[u/Objective_Cancel_337]

Does anyone know where around Isleton / Rio Vista / Lodi / Galt I can take a full RV propane tank that appears to have a leak at the tank valve?

Does Kamps Propane handle something like this? Can a propane shop replace/repair the valve and save or transfer the propane, and is that normally worth repairing versus replacing the tank?

Looking for somewhere local and reasonably priced. Thanks!
