The PowrTwin 459-019A foot valve housing, packaged (PKGD), is a complete replacement assembly that houses the foot valve mechanism on PowrTwin 12000 Plus DI and 6900 airless sprayers. It is installed at the bottom of the suction tube or directly on the pump intake, containing the check valve that prevents paint from flowing back into the container when the sprayer is not operating.
A cracked or warped housing can allow air to enter the suction line, causing loss of prime, erratic pressure, and reduced pump efficiency. This packaged assembly includes the housing and any necessary internal components for a complete, ready‑to‑install replacement, restoring reliable fluid intake and maintaining consistent spray performance.
