What to do if my AIRLESSCO Paint Sprayer primes but has no pressure?
- DDerek CooperAug 13, 2025
If your AIRLESSCO Paint Sprayer primes but has poor or no pressure, try the following: * Ensure the pressure isn't set too low by turning it up. * Clean or replace the gun filter, inlet filter, and/or manifold filter if they are clogged. * Service the outlet valve if it's fouled or worn. * Clean or replace the prime/pressure relief valve (866428) if it's bypassing. * Tighten the packing nut or repack the unit if the packings and/or piston are worn.
