Why Storch Airless LP Paint Sprayer pump ventilates but has low pressure?
- NNicole PierceAug 11, 2025
If the Storch Paint Sprayer pump ventilates but builds up virtually no pressure, or insufficient pressure, consider these potential causes: * The pressure might be set too low, so try increasing it. * The filter could be clogged; clean the gun filter, inlet filter, or device filter, or replace them as necessary. * The outlet valve may be jammed or worn; maintain the outlet valve. * The ventilation/pressure relief valve could be bypassed; clean or replace it. * The packings and/or piston might be worn; tighten the gland nut, replace the packing, and if needed, the piston.
