What to do if my Graco Paint Sprayer pump fails to operate?
- V
  Vicki BrownAug 21, 2025
  If the Graco Paint Sprayer pump fails to operate, first check for any restrictions in the line, ensure an adequate air supply, and verify that all valves are open. If those are not the cause, inspect the fluid hose and gun for obstructions, and make sure the fluid hose ID is appropriately sized. Another potential cause could be fluid dried on the displacement rod (119). If so, clean it and keep the packing nut wet-cup filled with Graco throat seal liquid (TSL).

What to do if my Graco Paint Sprayer pump operates but does not prime?

  Kelly PalmerAug 23, 2025
  If your Graco Paint Sprayer pump operates but does not prime, it might be due to held open or worn ball check valves or piston packings. Try to clear the valve and replace the packings. Also, check the suction hose o-ring (38); if it's worn, replace it.

How to prevent icing inside the motor of my Graco 24F150 Paint Sprayer?
- K
  kimberlyfriedmanAug 25, 2025
  If you're experiencing icing inside the motor of your Graco Paint Sprayer, it's likely because the air motor is operating at high pressure or a high cycle rate. To resolve this, reduce the pressure, cycle rate, or duty cycle of the motor. Also, reduce the dew point of compressed air in the moisture coalescing filter.

Why is the output low on both strokes of my Graco 24F150 Paint Sprayer?
- M
  Michael AndersonAug 27, 2025
  If your Graco Paint Sprayer pump operates but the output is low on both strokes, start by checking for any restrictions in the line, ensuring an adequate air supply, and verifying that the valves are open and not clogged. Additionally, inspect the fluid hose and gun for any obstructions, and make sure the fluid hose ID is not too small; clear any obstructions or use a hose with a larger ID. Finally, worn packings in the displacement pump can also cause low output; in this case, replace the packings.

- J
  jmillerAug 28, 2025
  If your Graco Paint Sprayer pump operates, but the output is low on the downstroke, it could be caused by ball check valves or piston packings being held open or worn. Clear the valve, and replace the packings.

Why is the output low on both strokes of my Graco 24F150 pump?
- D
  Dr. Matthew SimonAug 29, 2025
  If your Graco Paint Sprayer pump operates but the output is low on both strokes, the issue could stem from a restricted line, inadequate air supply, or closed/clogged valves. Ensure the line is clear, increase the air supply, and check that the valves are open. Another possibility is an obstructed fluid hose or gun, or a fluid hose with an ID that's too small. Make sure they are clear and consider using a hose with a larger ID. Finally, worn packings in the displacement pump can also cause this issue; if so, replace the packings.

Why is fluid being pumped visible in the packing nut wet-cup of my Graco 24F150?
- C
  Cynthia DonaldsonAug 31, 2025
  If you notice fluid being pumped is visible in the packing nut wet-cup of your Graco Paint Sprayer, this is likely due to worn throat packings. Try tightening the packing nut, and if that doesn't resolve the issue, replace the throat packings.

Why does my Graco Paint Sprayer have erratic pump speed?
- T
  Tina AlexanderSep 2, 2025
  If your Graco Paint Sprayer has an erratic or accelerated pump speed, it could be due to an exhausted fluid supply. Refill the fluid and prime the pump. Another cause could be held open or worn ball check valves or packings. In that case, clear the valve and replace the packings.
