705-106 Foot Valve Housing is a genuine OEM replacement component designed for Titan airless sprayers. The foot valve assembly sits inside the suction tube and prevents backflow of material when the sprayer is not running, ensuring prime is maintained and the pump stays loaded. A worn or damaged foot valve housing leads to loss of prime, erratic pressure, and difficulty starting.

The Titan 705-106 Foot Valve Housing is a critical component of the lower pump end. It houses the check valve that allows material to be drawn into the cylinder on the upstroke and seals the inlet on the downstroke. A functioning foot valve maintains prime, prevents backflow, and ensures consistent spray pressure.
Over time, debris, wear, or dried coating can cause the foot valve to stick or fail to seal, resulting in loss of prime, erratic pressure, or a sprayer that won't build pressure. Replacing the complete housing assembly (with new seals and valve) restores reliable pump performance.
| Holds prime | Prevents material from draining back into the container when pump stops |
|---|---|
| One‑way flow control | Allows material to enter the pump cylinder on upstroke, closes on downstroke |
| Sealing integrity | O‑rings and valve seat maintain hydraulic seal to build pressure |
| Loss of prime | Sprayer won't prime or loses prime immediately after stopping |
|---|---|
| Pressure fluctuation | Pressure surges or drops while spraying |
| Material leaking back | Material drains from suction tube when disconnected |
| Visible wear / debris | Damaged seat, worn o‑rings, or contamination inside housing |
Part 705-106 is an OEM replacement foot valve housing for Titan airless sprayers. Confirmed compatibility includes:
| Brand / Model | Component |
|---|---|
| Titan 740 IX | Foot valve housing assembly |
| Titan 740I | Foot valve housing assembly |
When replacing the foot valve housing, inspect these additional components to ensure a complete repair.
Cracks, dents, or corrosion can cause air leaks and loss of prime.
A clogged or damaged screen restricts material flow and can damage the new valve.
Worn packings can mimic foot valve symptoms; inspect if pressure issues persist.
