Frequently Asked Questions

It serves as a check valve to control fluid entering the pump while preventing reverse flow, ensuring stable and efficient suction.

Replace it whenever pump priming becomes difficult, fluid flow is inconsistent, or during a scheduled pump re‑build. A worn or damaged valve can lead to poor suction and performance issues.

While aftermarket valves may work, using the genuine Graco 15B874 ensures compatibility, proper material resistance, and reliable performance under high‑pressure cycles.
