Part 700-1025 is a syphon and bypass assembly used on select cart-mounted airless paint sprayers. This assembly manages material pickup from the paint container while allowing controlled fluid bypass during priming, pressure relief, and shutdown.

The 700-1025 Syphon and Bypass Assembly is a fluid-handling component responsible for drawing coating material into the pump while providing a controlled bypass path for priming, pressure relief, and recirculation.
Proper operation of the syphon and bypass system is critical for fast priming, stable pressure control, and safe shutdown. Worn tubing, leaking fittings, or a malfunctioning bypass path can result in poor prime, pressure fluctuation, or material leaks.
| Material pickup | Draws coating material from the container into the pump |
|---|---|
| Bypass flow | Allows controlled return flow during priming and pressure relief |
| System protection | Helps prevent over-pressurization during startup and shutdown |
| Poor priming | Difficulty drawing material into the pump |
|---|---|
| Leaks | Material leaking from hoses, fittings, or joints |
| Restricted bypass | Return flow blocked or inconsistent |
| Hose wear | Cracked, hardened, or collapsed tubing |
Part 700-1025 is compatible with the following airless sprayer models. Always confirm fitment using the correct parts diagram for your exact unit.
| Sprayer Model | Component |
|---|---|
| Airless Sprayer 440 XC | Syphon and Bypass Assembly (700-1025) |
| Airless Sprayer 550 XC | Syphon and Bypass Assembly (700-1025) |
| Airless Sprayer 690 GXC | Syphon and Bypass Assembly (700-1025) |
Clogged strainers restrict flow and affect priming.
Worn valves can cause pressure instability.
Air leaks at the inlet often mimic siphon issues.
