FAQs 

1.When should I replace the GPX 80 fluid section?

You may need to replace the fluid section when you notice loss of pressure, paint leaking past the packings, or difficulty priming. These symptoms indicate worn internal packings or valves that require rebuilding or full replacement.

2. Why is my GPX 80 not priming properly?

Priming issues often come from a clogged inlet filter, a worn prime/spray valve, or air leaks in the siphon set. Cleaning the screen and inspecting the hose connections usually resolves the problem, but worn valves may need replacement.

3. What causes pressure fluctuation while spraying?

Pressure fluctuation typically occurs when packings are worn, the piston is scratched, or the filter assembly is partially blocked. Replacing the filter and inspecting the pump packings will restore smooth pressure.

4. How do I know if the prime/spray valve needs replacement?

If the sprayer struggles to switch between prime and spray modes or leaks from the valve housing, the internal seals or ball may be worn. Replacing the valve assembly restores proper operation.

5. How often should I change the pump’s filter assembly?

Filters should be cleaned after every job and replaced when the mesh becomes damaged or clogged. Frequent filter maintenance helps protect the piston pump and prevents costly failures.
