Airless Spray Gun Blocking

Possible blocking causes commonly encountered when using airless spray guns

Blocked Airless Spray Gun

If your airless spray pump primes and pressurises but nothing happens when the trigger is pulled, and it is not the airless spray tip that is blocked, the actual spray gun hand piece could be where the problem is located.

The first thing that needs to be done is relieve all pressure from the airless spray system by opening the prime spray or bypass valve and turn the machine off.
