No. This check valve is designed for specific Craftsman air compressor models that use the matching thread size and discharge tube configuration. Always verify compatibility using the compressor model number and original part reference before installation.

Why is my compressor still leaking air after replacing the check valve?

If air leakage continues, inspect the pressure switch unloader valve, discharge tube fittings, and tank connections for additional leaks. Improper thread sealing or debris inside the valve port can also prevent proper sealing.

Can I replace the compressor check valve myself?

Many users can replace this check valve with standard hand tools. The repair usually involves depressurizing the tank, removing the discharge tube, unscrewing the old valve, and installing the replacement using proper thread sealant.

What does the Craftsman A19715 compressor check valve do?

The check valve allows compressed air to enter the tank while preventing air from flowing back into the compressor pump. This helps maintain tank pressure and allows the motor to restart more easily during normal compressor cycling.

Troubleshooting

The Craftsman A19715 Compressor Check Valve is an essential air compressor component that helps maintain tank pressure by allowing compressed air to flow in one direction only. It prevents backflow from the tank into the pump system and supports proper compressor restart operation.

Common Issues This Part Helps Resolve:

Air leaking continuously from the pressure switch area.
Compressor struggles to restart under pressure.
Tank pressure drops after shutdown.
Hissing sound near the check valve fitting.
Backflow of compressed air into the pump tube.

Continuous Air Leak After Shutdown.

Quick Check: Listen for hissing near the tank check valve connection after the compressor stops.

Fix Suggestion: Replace the A19715 compressor check valve if the internal seal no longer closes properly.

Prevention Tip: Drain tank moisture regularly to reduce internal corrosion and valve contamination.

Compressor Has Difficulty in Restarting.

Quick Check: Check whether compressed air is trapped in the discharge tube during startup.

Fix Suggestion: Install a new check valve if back pressure is preventing the motor from restarting normally.

Prevention Tip: Avoid running the compressor with excessive tank pressure beyond recommended limits.

Tank Loses Pressure at Overnight.

Quick Check: Monitor tank PSI while the compressor remains powered off.

Fix Suggestion: Inspect the check valve for worn internal components or debris preventing a tight seal.

Prevention Tip: Perform periodic inspections on air fittings and valve assemblies during maintenance.

Backflow into the Pump Discharge Tube.

Quick Check: Disconnect the discharge tube carefully and inspect for reverse airflow after shutdown.

Fix Suggestion: Replace the faulty A19715 valve if compressed air is flowing backward toward the pump head.

Prevention Tip: Keep the compressor tank clean and moisture-free to extend valve lifespan.

Clicking or Air Pulsing Near Valve Area.

Quick Check: Observe whether airflow pulses occur during compressor cycling.

Fix Suggestion: Inspect the internal valve spring and sealing mechanism for wear or sticking.

Prevention Tip: Replace aging check valves before excessive wear affects compressor performance.

Customer Experiences: Many users report that replacing the Craftsman A19715 check valve quickly resolved slow pressure build-up and eliminated air leaking back into the pump after shutdown.
