Dump Valve Washer for SprayTech, PowrTwin & PowrLiner Sprayers

The Titan 0294501 Dump Valve Washer is a genuine OEM replacement sealing washer used in the dump valve assembly on compatible SprayTech, PowrTwin, and PowrLiner airless sprayers. This washer creates a seal between the dump valve stem and the valve body, preventing paint leakage when the valve is closed.

Over time, dump valve washers can become flattened, hardened, cracked, or eroded by paint and solvents. A failed washer allows paint to seep past the dump valve, causing drips from the valve outlet, loss of pressure, or difficulty building prime. Replacing the washer restores a tight seal and reliable valve operation.

Service Guidance: When replacing the dump valve washer, inspect the valve stem and seat for scratches or pitting. Clean the valve body thoroughly. If the dump valve continues to leak after replacing the washer, the entire dump valve assembly may need replacement.

Frequently Asked Questions

The dump valve washer creates a seal between the dump valve stem and the valve body. When the dump valve is closed (normal spraying position), the washer prevents paint from leaking out of the dump port, helping maintain system pressure.

Common signs include: paint dripping from the dump valve outlet when the valve is in the closed position, loss of pressure during spraying, difficulty priming, or visible damage to the washer during inspection.

If the valve stem and seat are in good condition, replacing only the washer is sufficient. However, if the stem is scratched or the seat is pitted, the entire dump valve assembly should be replaced to ensure a proper seal.
