Part 107-015A is a foot valve housing used in the fluid intake system of compatible PowrLiner and PowrTwin sprayers. It houses the foot valve assembly, which prevents backflow and maintains prime in the pump. This replacement housing restores proper sealing and fluid flow when the original is cracked, warped, or worn.

The Titan 107-015A Foot Valve Housing is a critical fluid intake component that houses the foot valve assembly (ball, seat, and spring). It attaches to the bottom of the pump cylinder and ensures that fluid flows in only one direction – into the pump – while preventing backflow into the supply container when the sprayer is off.
A cracked, warped, or corroded foot valve housing can cause loss of prime, erratic spraying, or complete pump failure. Replacing the housing restores proper sealing, maintains consistent fluid supply to the piston pump, and helps eliminate nuisance re-priming issues.
| Houses foot valve | Contains ball, seat, and spring that act as a one-way check valve |
|---|---|
| Maintains prime | Prevents fluid from draining back into the supply container when pump stops |
| Seals intake path | Provides a leak‑tight connection between supply hose and pump cylinder |
| Cracks or splits | Visible cracks that allow air ingestion or fluid leaks |
|---|---|
| Warped sealing face | Housing bottom no longer flat, causing foot valve to seat improperly |
| Corrosion / pitting | Internal corrosion that damages the valve seat surface |
| Stripped threads | Threads that connect to pump cylinder are damaged |

When replacing the foot valve housing, inspect these associated components to ensure complete repair.
The internal check valve components wear over time. Replace them together with the housing for reliable sealing.
Cracks or loose fittings in the supply hose can introduce air and mimic foot valve failure.
Check threads and sealing surface on the pump where the foot valve housing screws in.
