If the Launcher makes a resonant sound when fired see CsvHonks.

If the launcher fails to reach the usual height and seems underpowered, it is usually due to inadequate trigger airflow. See CsvHonks.

The main valve may leak if bits of PVC get into the main valve seat. This generally happens when bits of PVC left over from the tapping operation on the pressure chamber find their way into the valve. See CsvValveCleaning. If it occurs repeatedly see CsvTankCleaning.

The Pressure Safety Valve can leak if bits of PVC get into the valve seat. See PsvCleaning.

The Pressure Safety Valves come preset at 100 psi from the vendor. They can be readily adjusted slightly if needed. See PsvAdjustment.

Dropping the Launcher on a hard surface can cause the PVC to fracture, especially at low temperature. In many cases this can be repaired. See CsvRepairs.
