The 0005311 Piston Spring is a practical replacement for contractors who need reliable pump performance and consistent spray quality. A weak, broken, or corroded spring prevents the pump from completing its full cycle, leading to erratic output, pressure loss, or complete pump failure . When rebuilding the fluid section or troubleshooting poor pump performance, inspect the piston spring for signs of fatigue, distortion, or breakage . Replace it if any doubt exists, as a weak spring can cause inconsistent operation even if not visibly broken . Always replace the spring during any fluid section rebuild to ensure proper pump function .
